New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At 7,354 square miles (19,050 km2), New Jersey is the fifth-smallest state in land area. But with close to 9.3 million residents, the state ranks 11th in population and first in population density. New Jersey's state capital is Trenton. Its most populous city is Newark. With the sole exception of Warren County, all 21 counties in the state lie within the combined statistical areas of New York City or Philadelphia. The state's largest metropolitan area falls within the New York metropolitan area.

New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and Swedish colonists founded the first European settlements in the state. The British later seized control of the region and established the Province of New Jersey, named after the largest of the Channel Islands, Jersey. The colony's fertile lands and relative religious tolerance drew a large and diverse population. New Jersey was among the Thirteen Colonies that opposed Great Britain, hosting numerous pivotal battles and military commands in the American Revolutionary War. The state remained in the Union during the American Civil War, and thereafter became a major center of manufacturing and immigration; it helped drive the nation's Industrial Revolution, and became the site of numerous technological and commercial innovations into the mid 20th century.

New Jersey's central location in the Northeast megalopolis helped fuel its rapid growth and suburbanization in the second half of the 20th century. At the turn of the 21st century, its economy increasingly diversified with major sectors including biotechnology, pharmaceuticals, specialized agriculture, and informational technology. New Jersey remains a major destination for immigrants with one of the most multicultural populations in the U.S. Echoing historical trends, the state has increasingly re-urbanized, with growth in the cities outpacing the suburbs since 2008. New Jersey is one of the wealthiest states in the U.S. with the third highest median household income as of 2019. Almost one-tenth of all households, or over 323,000 of 3.3 million, are millionaires, the highest per capita rate of millionaires of any state in the country. New Jersey's public school system consistently ranks at or among the top of all U.S. states.

Around 180 million years ago, during the Jurassic Period, New Jersey bordered North Africa. The pressure of the collision between North America and Africa gave rise to the Appalachian Mountains. Around 18,000 years ago, the Ice Age resulted in glaciers that reached New Jersey. As the glaciers retreated, they left behind Lake Passaic, as well as rivers, grasslands, swamps, and gorges.

New Jersey was originally settled by Native Americans with the Lenni-Lenape being dominant at the time of contact. Scheyichbi is the Lenape name for the land that is now New Jersey. The Lenape were several autonomous groups that practiced maize agriculture in order to supplement their hunting and gathering in the region surrounding the Delaware River, the lower Hudson River, and western Long Island Sound. The Lenape society was divided into matrilinear clans that were based upon common female ancestors. These clans were organized into three distinct phratries identified by their animal sign: Turtle, Turkey, and Wolf. They first encountered the Dutch in the early 17th century, and their primary relationship with the Europeans was through fur trade.

The Dutch were the first Europeans to lay claim to lands in New Jersey. The Dutch colony of New Netherland consisted of parts of modern Mid-Atlantic states. Although the European principle of land ownership was not recognized by the Lenape, Dutch West India Company policy required its colonists to purchase the land that they settled. The first to do so was Michiel Pauw who established a patronship called Pavonia in 1630 along the North River which eventually became the Bergen. Peter Minuit's purchase of lands along the Delaware River established the colony of New Sweden. The entire region became a territory of England on June 24, 1664, after an English fleet under the command of Colonel Richard Nicolls sailed into what is now New York Harbor and took control of Fort Amsterdam, annexing the entire province.

During the English Civil War, the Channel Island of Jersey remained loyal to the British Crown and gave sanctuary to the King. It was from the Royal Square in St Helier that Charles II of England was proclaimed King in 1649, following the execution of his father, Charles I. The North American lands were divided by Charles II, who gave his brother, the Duke of York (later King James II), the region between New England and Maryland as a proprietary colony (as opposed to a royal colony). James then granted the land between the Hudson River and the Delaware River (the land that would become New Jersey) to two friends who had remained loyal through the English Civil War: Sir George Carteret and Lord Berkeley of Stratton. The area was named the Province of New Jersey.

Since the state's inception, New Jersey has been characterized by ethnic and religious diversity. New England Congregationalists settled alongside Scots Presbyterians and Dutch Reformed migrants. While the majority of residents lived in towns with individual landholdings of 100 acres (40 ha), a few rich proprietors owned vast estates. English Quakers and Anglicans owned large landholdings. Unlike Plymouth Colony, Jamestown and other colonies, New Jersey was populated by a secondary wave of immigrants who came from other colonies instead of those who migrated directly from Europe. New Jersey remained agrarian and rural throughout the colonial era, and commercial farming developed sporadically. Some townships, such as Burlington on the Delaware River and Perth Amboy, emerged as important ports for shipping to New York City and Philadelphia. The colony's fertile lands and tolerant religious policy drew more settlers, and New Jersey's population had increased to 120,000 by 1775.

Settlement for the first 10 years of English rule took place along Hackensack River and Arthur Kill. Settlers came primarily from New York and New England. On March 18, 1673, Berkeley sold his half of the colony to Quakers in England, who settled the Delaware Valley region as a Quaker colony. (William Penn acted as trustee for the lands for a time.) New Jersey was governed very briefly as two distinct provinces, East and West Jersey, for 28 years between 1674 and 1702, at times part of the Province of New York or Dominion of New England.

In 1702, the two provinces were reunited under a royal governor, rather than a proprietary one. Edward Hyde, Lord Cornbury, became the first governor of the colony as a royal colony. Britain believed that he was an ineffective and corrupt ruler, taking bribes and speculating on land. In 1708, he was recalled to England. New Jersey was then ruled by the governors of New York, but this infuriated the settlers of New Jersey, who accused those governors of favoritism to New York. Judge Lewis Morris led the case for a separate governor, and was appointed governor by King George II in 1738.

New Jersey was one of the Thirteen Colonies that revolted against British rule in the American Revolution. The New Jersey Constitution of 1776 was passed July 2, 1776, just two days before the Second Continental Congress declared American Independence from Great Britain. It was an act of the Provincial Congress, which made itself into the State Legislature. To reassure neutrals, it provided that it would become void if New Jersey reached reconciliation with Great Britain. New Jersey representatives Richard Stockton, John Witherspoon, Francis Hopkinson, John Hart, and Abraham Clark were among those who signed the United States Declaration of Independence on July 4, 1776.

During the American Revolutionary War, British and American armies crossed New Jersey numerous times, and several pivotal battles took place in the state. Because of this, New Jersey today is often referred to as "The Crossroads of the American Revolution". The winter quarters of the Continental Army were established there twice by General George Washington in Morristown, which has been called "The Military Capital of the American Revolution.“

On the night of December 25–26, 1776, the Continental Army under George Washington crossed the Delaware River. After the crossing, they surprised and defeated the Hessian troops in the Battle of Trenton. Slightly more than a week after victory at Trenton, Continental Army forces gained an important victory by stopping General Cornwallis's charges at the Second Battle of Trenton. By evading Cornwallis's army, the Continental Army was able to make a surprise attack on Princeton and successfully defeated the British forces there on January 3, 1777. Emanuel Leutze's painting of Washington Crossing the Delaware became an icon of the Revolution.

Cotinental Army forces under Washington's command met British forces under General Henry Clinton at the Battle of Monmouth in an indecisive engagement in June 1778. Washington's forces attempted to take the British column by surprise. When the British army attempted to flank the Americans, the Continetal Army retreated in disorder. Their ranks were later reorganized and withstood the British charges.

In the summer of 1783, the Continental Congress met in Nassau Hall at Princeton University, making Princeton the nation's capital for four months. It was there that the Continental Congress learned of the signing of the Treaty of Paris, which ended the war.

On December 18, 1787, New Jersey became the third state to ratify the United States Constitution, which was overwhelmingly popular in New Jersey since it prevented New York and Pennsylvania from charging tariffs on goods imported from Europe. On November 20, 1789, New Jersey became the first in the newly-formed Union to ratify the Bill of Rights.

The 1776 New Jersey State Constitution gave the vote to "all inhabitants" who had a certain level of wealth. This included women and Black people, but not married women because they were not legally permitted to own property separately from their husbands. Both sides, in several elections, claimed that the other side had had unqualified women vote and mocked them for use of "petticoat electors", whether entitled to vote or not; on the other hand, both parties passed Voting Rights Acts. In 1807, the legislature passed a bill interpreting the constitution to mean universal white male suffrage, excluding paupers; the constitution was itself an act of the legislature and not enshrined as the modern constitution.

On February 15, 1804, New Jersey became the last northern state to abolish new slavery and enacted legislation that slowly phased out existing slavery. This led to a gradual decrease of the slave population. By the close of the American Civil War, about a dozen African Americans in New Jersey were still held in bondage. New Jersey voters eventually ratified the constitutional amendments banning slavery and granting rights to the United States' black population.

Industrialization accelerated in the northern part of the state following completion of the Morris Canal in 1831. The canal allowed for coal to be brought from eastern Pennsylvania's Lehigh Valley to northern New Jersey's growing industries in Paterson, Newark, and Jersey City.

In 1844, the second state constitution was ratified and brought into effect. Counties thereby became districts for the state senate, and some realignment of boundaries (including the creation of Mercer County) immediately followed. This provision was retained in the 1947 Constitution, but was overturned by the Supreme Court of the United States in 1962 by the decision Baker v. Carr. While the Governorship was stronger than under the 1776 constitution, the constitution of 1844 created many offices that were not responsible to him, or to the people, and it gave him a three-year term, but he could not succeed himself.

New Jersey was one of the few Union states (the others being Delaware and Kentucky) to select a candidate other than Abraham Lincoln twice in national elections, and sided with Stephen Douglas (1860) and George B. McClellan (1864) during their campaigns. McClellan, a native Philadelphian, had New Jersey ties and formally resided in New Jersey at the time; he later became Governor of New Jersey (1878–81). (In New Jersey, the factions of the Democratic party managed an effective coalition in 1860.) During the American Civil War, the state was led first by Republican governor Charles Smith Olden, then by Democrat Joel Parker. During the course of the war, between 65,000 and 80,000 soldiers from the state enlisted in the Union army; unlike many states, including some Northern ones, no battle was fought there.

In the Industrial Revolution, cities like Paterson grew and prospered. Previously, the economy had been largely agrarian, which was problematically subject to crop failures and poor soil. This caused a shift to a more industrialized economy, one based on manufactured commodities such as textiles and silk. Inventor Thomas Edison also became an important figure of the Industrial Revolution, having been granted 1,093 patents, many of which for inventions he developed while working in New Jersey. Edison's facilities, first at Menlo Park and then in West Orange, are considered perhaps the first research centers in the United States. Christie Street in Menlo Park was the first thoroughfare in the world to have electric lighting. Transportation was greatly improved as locomotion and steamboats were introduced to New Jersey.

Iron mining was also a leading industry during the middle to late 19th century. Bog iron pits in the southern New Jersey Pinelands were among the first sources of iron for the new nation. Mines such as Mt. Hope, Mine Hill and the Rockaway Valley Mines created a thriving industry. Mining generated the impetus for new towns and was one of the driving forces behind the need for the Morris Canal. Zinc mines were also a major industry, especially the Sterling Hill Mine.

New Jersey prospered through the Roaring Twenties. The first Miss America Pageant was held in 1921 in Atlantic City; the Holland Tunnel connecting Jersey City to Manhattan opened in 1927; and the first drive-in movie was shown in 1933 in Camden. During the Great Depression of the 1930s, the state offered begging licenses to unemployed residents, the zeppelin airship Hindenburg crashed in flames over Lakehurst, and the SS Morro Castle beached itself near Asbury Park after going up in flames while at sea.

Through both World Wars, New Jersey was a center for war production, especially naval construction. The Federal Shipbuilding and Drydock Company yards in Kearny and Newark and the New York Shipbuilding Corporation yard in Camden produced aircraft carriers, battleships, cruisers, and destroyers. New Jersey manufactured 6.8 percent of total United States military armaments produced during World War II, ranking fifth among the 48 states. In addition, Fort Dix (1917) (originally called "Camp Dix"),Camp Merritt (1917) and Camp Kilmer (1941) were all constructed to house and train American soldiers through both World Wars. New Jersey also became a principal location for defense in the Cold War. Fourteen Nike missile stations were constructed for the defense of the New York City and Philadelphia areas. PT-109, a motor torpedo boat commanded by Lt. (j.g.) John F. Kennedy in World War II, was built at the Elco Boatworks in Bayonne. The aircraft carrier USS Enterprise (CV-6) was briefly docked at the Military Ocean Terminal in Bayonne in the 1950s before she was sent to Kearney to be scrapped. In 1962, the world's first nuclear-powered cargo ship, the NS Savannah, was launched at Camden.

In 1951, the New Jersey Turnpike opened, facilitating efficient travel by car and truck between North Jersey and metropolitan New York and South Jersey and metropolitan Philadelphia. 1959, Air Defense Command deployed the CIM-10 Bomarc surface-to-air missile to McGuire Air Force Base. On June 7, 1960, an explosion in a CIM-10 Bomarc missile fuel tank caused the accident and subsequent plutonium contamination.

In the 1960s, race riots erupted in many of the industrial cities of North Jersey. The first race riots in New Jersey occurred in Jersey City on August 2, 1964. Several others ensued in 1967, in Newark and Plainfield. Other riots followed the assassination of Martin Luther King Jr. in April 1968, just as in the rest of the country. A riot occurred in Camden in 1971. As a result of an order from the New Jersey Supreme Court to fund schools equitably, the New Jersey legislature passed an income tax bill in 1976. Prior to this bill, the state had no income tax.

In the early part of the 2000s, two light rail systems were opened: the Hudson–Bergen Light Rail in Hudson County and the River Line between Camden and Trenton. The intent of these projects was to encourage transit-oriented development in North Jersey and South Jersey, respectively. The HBLR in particular was credited with a revitalization of Hudson County and Jersey City in particular. Urban revitalization has continued in North Jersey in the 21st century. In 2014, Jersey City's Census-estimated population was 262,146, with the largest population increase of any municipality in New Jersey since 2010, representing an increase of 5.9% from the 2010 U.S. census, when the city's population was enumerated at 247,597. Between 2000 and 2010 Newark experienced its first population increase since the 1950s, and by 2020 had rebounded to 311,549.

The state of New Jersey is bordered on the north and northeast by New York (parts of which are across the Hudson River, Upper New York Bay, the Kill Van Kull, Newark Bay, and the Arthur Kill); on the east by the Atlantic Ocean; on the southwest by Delaware across Delaware Bay; and on the west by Pennsylvania across the Delaware River. This is New Jersey's only straight border.

New Jersey is broadly divided into three geographic regions: North Jersey, Central Jersey, and South Jersey. Some New Jersey residents do not consider Central Jersey a region in its own right, but others believe it is a separate geographic and cultural area distinct from the North and South.

Within those regions are five distinct areas divided by natural geography and population concentration. Northeastern New Jersey, often referred to as the Gateway Region, lies closest to Manhattan in New York City, and up to a million residents commute daily into the city for work, many via public transportation. Northwestern New Jersey, often referred to as the Skylands Region, is more wooded, rural, and mountainous. The chief tree of the northern forests is the oak. The Jersey Shore, along the Atlantic Coast in Central and South Jersey, has its own unique natural, residential, and cultural characteristics owing to its location by the ocean. The Delaware Valley includes the southwestern counties of the state, which reside within the Delaware Valley surrounding Philadelphia. The Pine Barrens region is in the southern interior of New Jersey; covered rather extensively by mixed pine and oak forest. The Pine Barrens has a lower population density than most of the rest of the state. Forests cover 45%, or approximately 2.1 million acres, of New Jersey's land area.

The federal Office of Management and Budget divides New Jersey's counties into seven metropolitan statistical areas with 16 counties included in either the New York City or Philadelphia metro areas. Four counties have independent metro areas, and Warren County is part of the Pennsylvania-based Lehigh Valley metro area. New Jersey is located at the center of the Northeast megalopolis, the nation's second most populated region.

High Point in Montague Township, Sussex County is the state's highest elevation at 1,803 feet (550 m) above sea level. The state's highest prominence is Kitty Ann Mountain in Morris County, rising 892 feet (272 m). The Palisades are a line of steep cliffs on the west side of the Hudson River in Bergen and Hudson Counties. Major New Jersey rivers include the Hudson, Delaware, Raritan, Passaic, Hackensack, Rahway, Musconetcong, Mullica, Rancocas, Manasquan, Maurice, and Toms rivers. Due to New Jersey's peninsular geography, both sunrise and sunset are visible over water from different points on the Jersey Shore.

There are two climatic conditions in the state. The south, central, and northeast parts of the state have a humid subtropical climate, while the northwest has a humid continental climate (microthermal), with much cooler temperatures due to higher elevation. New Jersey receives between 2,400 and 2,800 hours of sunshine annually.

Climate change is affecting New Jersey faster than much of the rest of the United States. As of 2019, New Jersey was one of the fastest-warming states in the nation. Since 1895, average temperatures have climbed by almost 3.6 Â°F (2.0 Â°C), double the average for the other Lower 48 states.

Summers are typically hot and humid, with statewide average high temperatures of 82–87 Â°F (28–31 Â°C) and lows of 60–69 Â°F (16–21 Â°C); however, temperatures exceed 90 Â°F (32 Â°C) on average 25 days each summer, exceeding 100 Â°F (38 Â°C) in some years. Winters are usually cold, with average high temperatures of 34–43 Â°F (1–6 Â°C) and lows of 16 to 28 Â°F (−9 to −2 Â°C) for most of the state, but temperatures can, for brief periods, fall below 10 Â°F (−12 Â°C) and sometimes rise above 50 Â°F (10 Â°C). Northwestern parts of the state have significantly colder winters with sub-0 Â°F (−18 Â°C) being an almost annual occurrence. Spring and autumn may feature wide temperature variations, with lower humidity than summer. The USDA Plant Hardiness Zone classification ranges from 6 in the northwest of the state, to 7B near Cape May. All-time temperature extremes recorded in New Jersey include 110 Â°F (43 Â°C) on July 10, 1936, in Runyon, Middlesex County and −34 Â°F (−37 Â°C) on January 5, 1904, in River Vale, Bergen County.

Average annual precipitation ranges from 43 to 51 inches (1,100 to 1,300 mm), uniformly spread throughout the year. Average snowfall per winter season ranges from 10–15 inches (25–38 cm) in the south and near the seacoast, 15–30 inches (38–76 cm) in the northeast and central part of the state, to about 40–50 inches (1.0–1.3 m) in the northwestern highlands, but this often varies considerably from year to year. Precipitation falls on an average of 120 days a year, with 25 to 30 thunderstorms, most of which occur during the summer.

During winter and early spring, New Jersey can experience "nor'easters", which are capable of causing blizzards or flooding throughout the northeastern United States. Hurricanes and tropical storms (such as Tropical Storm Floyd in 1999), tornadoes, and earthquakes are rare, although New Jersey was impacted by a hurricane in 1903, and Hurricane Sandy on October 29, 2012, with the storm making landfall in the state with top winds of 90 mph (145 km/h).

For its overall population and nation-leading population density, New Jersey has a relative paucity of classic large cities. This paradox is most pronounced in Bergen County, New Jersey's most populous county, whose 955,732 residents enumerated at the 2020 U.S. Census inhabited 70 municipalities, the most populous being Hackensack, with 44,522 residents estimated in 2018. Many urban areas extend far beyond the limits of a single large city, as New Jersey cities (and indeed municipalities in general) tend to be geographically small; three of the four largest cities in New Jersey by population have under 20 square miles (52 km2) of land area, and eight of the top ten, including all of the top five have a land area under 30 square miles (78 km2). As of the 2010 United States census[update], only four municipalities had populations in excess of 100,000, although Edison and Woodbridge came very close.

Residents of New Jersey are most commonly referred to as New Jerseyans or, less commonly, as New Jerseyites. According to the 2020 United States census, New Jersey had a population of 9,288,994, a 5.7% increase since the 2010 U.S. census, which counted 8,791,894 residents. It ranked as the eleventh-most populous state in the country, and the most densely populated, at 1,185 residents per square mile (458 per km2); New Jersey was the state where every country was deemed "urban" as defined by the Census Bureau's Combined Statistical Area. Most of the population resides in the counties surrounding New York City and Philadelphia, and along the eastern Jersey Shore; the extreme southern and northwestern counties are relatively less dense overall. New Jersey's center of population is the borough of Milltown in Middlesex County, just east of the New Jersey Turnpike, which is part of the New York metropolitan area and located in the middle of the Northeast megalopolis, with over 50 million residents.

As of 2019, New Jersey was the third wealthiest U.S. state by median household income, behind Maryland and Massachusetts; the state's median household income was over $85,000 compared to the national average of roughly $65,000. Conversely, New Jersey's poverty rate of 9.4% was slightly lower than the national average of 11.4%, and the sixth lowest of the fifty states, Washington, D.C., and Puerto Rico. This is attributed partly to the fact that most of New Jersey consists of suburbs of New York City and Philadelphia, which are major economic and financial centers. Other factors include the state having the highest number of millionaires both per capita and per square mile in the U.S., and hosting more scientists and engineers per square mile than anywhere else in the world.

New Jersey is one of the most ethnically and religiously diverse states in the United States. Nearly one-fourth of New Jerseyans (22.7%) were foreign born, compared to the national average of 13.5%. As of 2011, 56.4% of New Jersey's children under the age of one belonged to racial or ethnic minority groups, meaning that they had at least one parent who was not non-Hispanic white. The 2019 Vintage Year Census estimated that the state's ethnic makeup was as follows: 71.9% White alone, 15.1% Black or African American alone, 10.0% Asian alone, 0.6% American Indian and Alaska Native alone, 0.1% Native Hawaiian and Other Pacific Islander alone, and 2.3% Two or more races. Hispanic or Latino accounted for 20.9%, while White alone (non-Hispanic or Latino) accounted for 54.6% of the population.

New Jersey has the second-largest Jewish population by percentage (after New York); the largest Muslim population by percentage; the largest population of Peruvians in the U.S.; the largest population of Cubans outside Florida; the third-highest Asian population by percentage; and the second highest Italian population, according to the 2000 Census. African Americans, Hispanics (Puerto Ricans and Dominicans), West Indians, Arabs, and Brazilian and Portuguese Americans are also high in number. Overall, New Jersey has the third-largest Korean population, with Bergen County home to the highest Korean concentration per capita of any U.S. county (6.9% in 2011). New Jersey also has the fourth-largest Filipino population, and fourth-largest Chinese population, per the 2010 U.S. Census.

New Jersey has the-third highest Indian population of any state by absolute numbers and the highest by percentage, with India Square in Jersey City, Hudson County, hosting the highest concentration of Asian Indians in the Western Hemisphere. A study by the Pew Research Center found that in 2013, New Jersey was the only U.S. state in which immigrants born in India constituted the largest foreign-born nationality, representing roughly 10% of all foreign-born residents in the state.Central New Jersey, particularly Edison and surrounding Middlesex County, has the highest concentration of Indians, at nearly 20% in 2020; Little India is the largest and most diverse South Asian cultural hub in the United States.[100][101] The area includes a sprawling Chinatown and Koreatown running along New Jersey Route 27.[102]Monroe Township in Middlesex County has experienced a particularly rapid growth rate in its Indian American population with an estimated 5,943 (13.6%) as of 2017,[103] which was 23 times the 256 (0.9%) counted at the 2000 Census; Diwali is celebrated by the township as a Hindu holiday. In Middlesex County, election ballots are printed in English, Spanish, Gujarati, Hindi, and Punjabi.[104]Robbinsville, in neighboring Mercer County, hosts the world's largest Hindu temple outside India.[105]Carteret's Punjabi Sikh community, variously estimated at upwards of 3,000, is the largest concentration of Sikhs in the state.[106]Bergen County is home to America's largest Malayali community.[107]

In 2010, unauthorized immigrants numbered roughly 550,000,[117] or an estimated 6.2% of the population, the fifth-highest percentage of any state in the U.S.[118] The municipalities of Camden, Jersey City, and Newark are considered sanctuary cities for illegal immigrants.[119]

For further information on various ethnoracial groups and neighborhoods prominently featured within New Jersey, see the following articles:

As of 2011, 56.4% of New Jersey's population younger than age 1 were minorities (meaning that they had at least one parent who was not non-Hispanic white).[120]

Note: Births in table do not add up, because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number.

As of 2010, 71.31% (5,830,812) of New Jersey residents age 5 and older spoke English at home as a primary language, while 14.59% (1,193,261) spoke Spanish, 1.23% (100,217) Chinese (which includes Cantonese and Mandarin), 1.06% (86,849) Italian, 1.06% (86,486) Portuguese, 0.96% (78,627) Tagalog, and Korean was spoken as a main language by 0.89% (73,057) of the population over the age of five. In total, 28.69% (2,345,644) of New Jersey's population age 5 and older spoke a mother language other than English.[128]

A diverse collection of languages has since evolved amongst the state's population, given that New Jersey has become cosmopolitan and is home to ethnic enclaves of non-English-speaking communities:[129][130][131][132]

By number of adherents, the largest denominations in New Jersey, according to the Association of Religion Data Archives in 2010, were the Roman Catholic Church with 3,235,290; Islam with 160,666; and the United Methodist Church with 138,052.[140] In September 2021, the State of New Jersey aligned with the World Hindu Council to declare October as Hindu Heritage Month. The world's largest Hindu temple was inaugurated in Robbinsville, Mercer County, in central New Jersey during 2014, a BAPS temple.[141] In January 2018, Gurbir Grewal became the first Sikh American state attorney general in the United States.[142] In January 2019, Sadaf Jaffer became the first female Muslim American mayor, first female South Asian mayor, and first female Pakistani-American mayor in the United States, of Montgomery in Somerset County.[143]

Islamic Center of Passaic County, Paterson, Passaic County, was founded in 1990. New Jersey is home to the highest Muslim population concentration in the U.S. (3%), and Paterson, which houses the Islamic Center of Passaic County, is the epicenter of New Jersey's Muslim community, leading South Paterson to be nicknamed Little Istanbul and Little Ramallah.[145]

The U.S. Bureau of Economic Analysis estimates that New Jersey's gross state product in the fourth quarter of 2018 was $639.8 billion.[146] New Jersey's estimated taxpayer burden in 2015 was $59,400 per taxpayer.[147] New Jersey is nearly $239 billion in debt.[148]

New Jersey's per capita gross state product routinely ranks one of the highest in the United States. In 2020, New Jersey had the highest number of millionaires both per capita and per square mile in the United States, approximately 9.76% of households. The state is ranked second in the nation by the number of places with per capita incomes above national average with 76.4%. Nine of New Jersey's counties are among the 100 wealthiest U.S. counties.

New Jersey has seven tax brackets that determine state income tax rates, which range from 1.4% (for income below $20,000) to 8.97% (for income above $500,000).[149]

The standard sales tax rate as of January 1, 2018, is 6.625%, applicable to all retail sales unless specifically exempt by law. This rate, which is comparably lower than that of New York City, often attracts numerous shoppers from New York City, often to suburban Paramus, New Jersey, which has five malls, one of which (the Garden State Plaza) has over 2 million square feet (200,000 m2) of retail space. Tax exemptions include most food items for at-home preparation, medications, most clothing, footwear and disposable paper products for use in the home.[150] There are 27 Urban Enterprise Zone statewide, including sections of Paterson, Elizabeth, and Jersey City. In addition to other benefits to encourage employment within the zone, shoppers can take advantage of a reduced 3.3125% sales tax rate (half the rate charged statewide) at eligible merchants.[151][152][153]

New Jersey has the highest cumulative tax rate of all 50 states with residents paying a total of $68 billion in state and local taxes annually with a per capita burden of $7,816 at a rate of 12.9% of income.[154] All real property located in the state is subject to property tax unless specifically exempted by statute. New Jersey does not assess an intangible personal property tax or an estate tax, but it does impose an inheritance tax (which is levied only on heirs who are not direct descendants).[155]

New Jersey consistently ranks as having one of the highest proportional levels of disparity of any state in the United States, based upon what it receives from the federal government relative to what it gives. In 2015, WalletHub ranked New Jersey the state least dependent upon federal government aid overall and having the fourth lowest return on taxpayer investment from the federal government, at 48 cents per dollar.[156]

New Jersey has one of the highest tax burdens in the nation.[157] Factors for this include the large federal tax liability which is not adjusted for New Jersey's higher cost of living and Medicaid funding formulas.

New Jersey's economy is multifaceted, featuring the pharmaceutical industry, biotechnology, information technology, the financial industry, chemical development, telecommunications, food processing, electric equipment, printing, publishing, and tourism. New Jersey's agricultural outputs are nursery stock, horses, vegetables, fruits and nuts, seafood, and dairy products.[158] New Jersey ranks second among states in blueberry production, third in cranberries and spinach, and fourth in bell peppers, peaches, and head lettuce.[159] The state harvests the fourth-largest number of acres planted with asparagus.[160]

New Jersey has a strong scientific economy and is home to major pharmaceutical and telecommunications firms, drawing on the state's large and well-educated labor pool. There is also a strong service economy in retail sales, education, and real estate, serving residents who work in New York City or Philadelphia. Thomas Edison invented the first electric light bulb at his home in Menlo Park, Edison in 1879. New Jersey is also a key participant in the renewable wind industry. New Jersey has more scientists and engineers per square mile than anywhere in the world,[161] and is a global leader in pharmaceuticals, biotechnology, life sciences, and technology.[162][163]

Shipping is a key industry in New Jersey because of the state's strategic geographic location, the Port of New York and New Jersey being the busiest port on the East Coast. The Port Newark-Elizabeth Marine Terminal was the world's first container port and today is one of the world's largest.

New Jersey hosts numerous business headquarters, including twenty-four Fortune 500 companies.[164]Paramus in Bergen County has become the top retail ZIP code (07652) in the United States, with the municipality generating over US$6 billion in annual retail sales.[165] Several New Jersey counties, including Somerset (7), Morris (10), Hunterdon (13), Bergen (21), and Monmouth (42), have been ranked among the highest-income counties in the United States.

New Jersey's location at the center of the Northeast megalopolis and its extensive transportation system have put over one-third of all United States residents and many Canadian residents within overnight distance by land. This accessibility to consumer revenue has enabled seaside resorts such as Atlantic City and the remainder of the Jersey Shore, as well as the state's other natural and cultural attractions, to contribute significantly to the record 111 million tourist visits to New Jersey in 2018, providing US$44.7 billion in tourism revenue, directly supporting 333,860 jobs, sustaining more than 531,000 jobs overall including peripheral impacts, and generating US$5 billion in state and local tax revenue.[166]

In 1976, a referendum by Jersey voters approved casino gambling in Atlantic City, where the first legalized casino opened in 1978.[167] At that time, Las Vegas was the only other casino resort in the country.[168] Today, several casinos lie along the Atlantic City Boardwalk, the first and longest boardwalk in the world being 5.5 miles long.[169] Atlantic City experienced a dramatic contraction in its stature as a gambling destination after 2010, including the closure of multiple casinos since 2014, spurred by competition from the advent of legalized gambling in other northeastern U.S. states.[170][171] On February 26, 2013, Governor Chris Christie signed online gambling into law.[172]Sports betting has become a growing source of gambling revenue in New Jersey since being legalized across the nation by the U.S. Supreme Court on May 14, 2018.[173]

Some mining activity of zinc, iron, and manganese still takes place in the area in and around the Franklin Furnace.

Although New Jersey is home to many energy-intensive industries, its energy consumption is only 2.7% of the U.S. total, and its carbon dioxide emissions are 0.8% of the U.S. total. New Jersey's electricity comes primarily from natural gas and nuclear power.[174] New Jersey is seventh in the nation in solar power installations,[175] enabled by one of the country's most favorable net metering policies and renewable portfolio standard. The state has more than 140,000 solar installations.[176]

As of the 2020-2021 school year, there were 686 operating districts in the state. Of these, 599 were traditional public school districts and 87 were charter school districts.[178][179] The NJDOE reported a total district enrollment of 1,362,400 students, the lowest total enrollment since the early 2000s, though these figures don't consider homeschooled students or those attending out-of-state schools.[180]

Secretary of Education Rick Rosenberg, appointed by Governor Jon Corzine, created the Education Advancement Initiative (EAI) to increase college admission rates by 10% for New Jersey's high school students, decrease dropout rates by 15%, and increase the amount of money devoted to schools by 10%. Rosenberg retracted this plan when criticized for taking the money out of healthcare to fund this initiative.

New Jersey is known for the quality of its education. In 2015, the state spent more per each public school student than any other U.S. state except New York, Alaska, and Connecticut, amounting to $18,235 spent per pupil; over 50% of the expenditure was allocated to student instruction.[181]

According to 2011 Newsweek statistics, students of High Technology High School in Lincroft, Monmouth County and Bergen County Academies in Hackensack, Bergen County registered average SAT scores of 2145 and 2100, respectively,[182] representing the second- and third-highest scores, respectively, of all listed U.S. high schools.[182]

Princeton University in Princeton, Mercer County, one of the world's most prominent research universities, is often featured at or near the top of various national and global university rankings, topping the 2023 list, alongside those of several previous consecutive years, from U.S. News & World Report.[183] In 2013, Rutgers University, headquartered in New Brunswick, Middlesex County as the flagship institution of higher education in New Jersey, regained medical and dental schools,[184] augmenting its profile as a national research university as well.[185]

In 2014, New Jersey's school systems were ranked at the top of all fifty U.S. states by financial website Wallethub.com.[186] In 2018, New Jersey's overall educational system was ranked second among all states to Massachusetts by U.S. News & World Report. In both 2019 and 2020, Education Week also ranked New Jersey public schools the best of all U.S. states.

Nine New Jersey high schools were ranked among the top 25 in the U.S. on the Newsweek "America's Top High Schools 2016" list, more than from any other state.[187] A 2017 UCLA Civil Rights project found that New Jersey has the sixth-most segregated classrooms in the United States.[188]

New Jersey has continued to play a prominent role as a U.S. cultural nexus. Like every state, New Jersey has its own cuisine, religious communities, museums, and halls of fame.

New Jersey is the birthplace of modern inventions such as: FM radio, the motion picture camera, the lithium battery, the light bulb, transistors, and the electric train. Other New Jersey creations include: the drive-in movie, the cultivated blueberry, cranberry sauce, the postcard, the boardwalk, the zipper, the phonograph, saltwater taffy, the dirigible, the seedless watermelon,[189] the first use of a submarine in warfare, and the ice cream cone.[190]

Diners are iconic to New Jersey. The state is home to many diner manufacturers and has over 600 diners, more than any other place in the world.[191]

New Jersey is the only state without a state song. I'm From New Jersey is incorrectly listed on many websites as being the New Jersey state song, but it was not even a contender when in 1996 the New Jersey Arts Council submitted their suggestions to the New Jersey Legislature.[192]

New Jersey is frequently the target of jokes in American culture,[193] especially from New York City-based television shows, such as Saturday Night Live. Academic Michael Aaron Rockland attributes this to New Yorkers' view that New Jersey is the beginning of Middle America. The New Jersey Turnpike, which runs between two major East Coast cities, New York City and Philadelphia, is also cited as a reason, as people who traverse through the state may only see its industrial zones.[194] Reality television shows like Jersey Shore and The Real Housewives of New Jersey have reinforced stereotypical views of New Jersey culture,[195] but Rockland cited The Sopranos and the music of Bruce Springsteen as exporting a more positive image.[194]

New Jersey is known for several foods developed within the region, including Taylor Ham (also known as pork roll), sloppy joe sandwiches, tomato pies, salt water taffy, and Texas wieners. New York City cuisine has an influence on North Jersey's cuisine, and in Philadelphia cuisine influences South Jersey.

New Jersey third-largest industry is food and agriculture just behind pharmaceuticals and tourism. New Jersey is one of the top 10 producers of blueberries, cranberries, peaches, tomatoes, bell peppers, eggplant, cucumbers, apples, spinach, squash, and asparagus in the United States. Many restaurants in the state get locally grown ingredients because of this.[196]

Campbell's Soup Company has been headquartered in Camden since 1869.[197]Goya Foods, the largest Hispanic-owned food company in the United States, operates a corporate headquarters in Jersey City.[198]

Several states with substantial Italian American populations take credit for the development of submarine sandwiches, including New Jersey.[199]

New Jersey has long been an important origin for both rock and rap music. Prominent musicians from or with significant connections to New Jersey include:

New Jersey currently has six teams from major professional sports leagues playing in the state, although one Major League Soccer team and two National Football League teams identify themselves as being from the New York metropolitan area.

The National Hockey League's New Jersey Devils, based in Newark at the Prudential Center, is the only major league sports franchise to bear the state's name. Founded in 1974 in Kansas City, Missouri, as the Kansas City Scouts, the team played in Denver, Colorado, as the Colorado Rockies from 1976 until the spring of 1982 when naval architect, businessman, and Jersey City native John J. McMullen purchased, renamed, and moved the franchise to Brendan Byrne Arena in East Rutherford's Meadowlands Sports Complex. While the team had mostly losing records in Kansas City, Denver, and its first years in New Jersey, the Devils began to improve in the late 1980s and early 1990s under Hall of Fame president and general manager Lou Lamoriello. The team made the playoffs for the Stanley Cup in 2001 and 2012, and won it in 1995, 2000, and 2003. The organization is the youngest of the nine major league teams in the New York metropolitan area. The Devils have established a following throughout the northern and central portions of the state, carving a place in a media market once dominated by the New York Rangers and Islanders.

In 2018, the Philadelphia Flyers renovated and expanded their training facility, the Virtua Center Flyers Skate Zone, in Voorhees Township in the southern portion of the state.[207]

The New York Metropolitan Area's two National Football League teams, the New York Giants and the New York Jets, play at MetLife Stadium in East Rutherford's Meadowlands Sports Complex.[208] Built for about $1.6 billion,[209] the venue is the most expensive stadium ever built.[206] On February 2, 2014, MetLife Stadium hosted Super Bowl XLVIII.

The New York Red Bulls of Major League Soccer play in Red Bull Arena, a soccer-specific stadium in Harrison across the Passaic River from downtown Newark. On July 27, 2011, Red Bull Arena hosted the 2011 MLS All-Star Game.[210]

From 1977 to 2012, New Jersey had a National Basketball Association team, the New Jersey Nets. WNBA's New York Liberty played in New Jersey from 2011 to 2013 while their primary home arena, Madison Square Garden was undergoing renovations.[211] In 2016, the Philadelphia 76ers of the NBA opened their new headquarters and training facility, the Philadelphia 76ers Training Complex, in Camden.[212]

The Meadowlands Sports Complex is home to the Meadowlands Racetrack, one of three major harness racing tracks in the state. The Meadowlands Racetrack and Freehold Raceway in Freehold are two of the major harness racing tracks in North America. Monmouth Park Racetrack in Oceanport is a popular spot for thoroughbred racing in New Jersey and the northeast. It hosted the Breeders' Cup in 2007, and its turf course was renovated in preparation.

New Jerseyans' collegiate allegiances are predominantly split among the three major NCAA Division I programs in the state: the Rutgers University (New Jersey's flagship state university) Scarlet Knights, members of the Big Ten Conference; the Seton Hall University (the state's largest Catholic university) Pirates, members of the Big East Conference; and the Princeton University (the state's Ivy League university) Tigers.

The intense rivalry between Rutgers and Princeton athletics began with the first intercollegiate football game in 1869. The schools have not met on the football field since 1980, but they continue to play each other annually in all other sports offered by the two universities.

Rutgers, which fields 24 teams in various sports, is nationally known for its football program, with a 6–4 all-time bowl record; and its women's basketball programs, which appeared in a National Final in 2007. In 2008 and 2009, Rutgers expanded their football home, Rutgers Stadium, now called SHI Stadium, on the Busch Campus. The basketball teams play at the Rutgers Athletic Center on Livingston Campus. Both venues and campuses are in Piscataway, across the Raritan River from New Brunswick. The university also fields men's basketball and baseball programs. Rutgers' fans live mostly in the western parts of the state and Middlesex County; its alumni base is the largest in the state.

Rutgers' satellite campuses in Camden and Newark each field their own athletic programs—the Rutgers–Camden Scarlet Raptors and the Rutgers–Newark Scarlet Raiders—which both compete in NCAA Division III.

Seton Hall fields no football team, but its men's basketball team is one of the Big East's storied programs. No New Jersey team has won more games in the NCAA Division I men's basketball tournament, and it is the state's only men's basketball program to reach a modern National Final. The Pirates play their home games at Prudential Center in downtown Newark, about 4 miles (6 km) from the university's South Orange campus. Their fans hail largely from the predominantly Roman Catholic areas of the northern part of the state and the Jersey Shore. The annual inter-conference rivalry game between Seton Hall and Rutgers, whose venue alternates between Newark and Piscataway, the Garden State Hardwood Classic, is planned through 2026.[213]

The state's other Division I schools include the Monmouth University Hawks (West Long Branch), the New Jersey Institute of Technology (NJIT) Highlanders (Newark), the Rider University Broncs (Lawrenceville), and the Saint Peter's University Peacocks and Peahens (Jersey City).

Fairleigh Dickinson University competes in both Division I and Division III. It has two campuses, each with its own sports teams. The teams at the Metropolitan Campus are known as the FDU Knights, and compete in the Northeast Conference and NCAA Division I. The college at Florham (FDU-Florham) teams are known as the FDU-Florham Devils and compete in the Middle Atlantic Conferences' Freedom Conference and NCAA Division III.

Among the various Division III schools in the state, the Stevens Institute of Technology Ducks have fielded the longest continuously running collegiate men's lacrosse program in the country. 2009 marked the 125th season.

New Jersey high schools are divided into divisions under the New Jersey State Interscholastic Athletic Association (NJSIAA).[214]'[215]

Motion picture technology was developed by Thomas Edison, with much of his early work done at his West Orange laboratory. Edison's Black Maria was the first motion picture studio. America's first motion picture industry started in 1907 in Fort Lee and the first studio was constructed there in 1909.[219]DuMont Laboratories in Passaic developed early sets and made the first broadcast to the private home.

A number of television shows and films have been filmed in New Jersey. Since 1978, the state has maintained a Motion Picture and Television Commission to encourage filming in-state.[220] New Jersey has long offered tax credits to television producers. Governor Chris Christie suspended the credits in 2010, but the New Jersey State Legislature in 2011 approved the restoration and expansion of the tax credit program. Under bills passed by both the state Senate and Assembly, the program offers 20 percent tax credits (22% in urban enterprise zones) to television and film productions that shoot in the state and meet set standards for hiring and local spending.[221] When Governor Phil Murphy took office, he instated the New Jersey Film & Digital Media Tax Credit Program in 2018 and expanded it in 2020. The benefits include a 30% tax credit on film projects and a 40% subsidy for studio developments.[222]

The New Jersey Turnpike is one of the most prominent and heavily trafficked roadways in the United States. This toll road, which overlaps with Interstate 95 for much of its length, carries traffic between Delaware and New York, and up and down the East Coast in general. Commonly referred to as simply "the Turnpike", it is known for its numerous rest areas named after prominent New Jerseyans.

The Garden State Parkway, or simply "the Parkway", carries relatively more in-state traffic than interstate traffic and runs from New Jersey's northern border to its southernmost tip at Cape May. It is the main route that connects the New York metropolitan area to the Jersey Shore. With a total of fifteen travel and six shoulder lanes, the Driscoll Bridge on the Parkway, spanning the Raritan River in Middlesex County, is the widest motor vehicle bridge in the world by number of lanes as well as one of the busiest.[225]

New Jersey is connected to New York City via various key bridges and tunnels. The double-decked George Washington Bridge carries the heaviest load of motor vehicle traffic of any bridge in the world, at 102 million vehicles per year, across fourteen lanes.[223][224] It connects Fort Lee, New Jersey to the Washington Heights neighborhood of Upper Manhattan, and carries Interstate 95 and U.S. Route 1/9 across the Hudson River. The Lincoln Tunnel connects to Midtown Manhattan carrying New Jersey Route 495, and the Holland Tunnel connects to Lower Manhattan carrying Interstate 78. New Jersey is also connected to Staten Island by three bridges—from north to south, the Bayonne Bridge, the Goethals Bridge, and the Outerbridge Crossing.

New Jersey has interstate compacts with all three of its neighboring states. The Port Authority of New York and New Jersey, the Delaware River Port Authority (with Pennsylvania), the Delaware River Joint Toll Bridge Commission (with Pennsylvania), and the Delaware River and Bay Authority (with Delaware) operate most of the major transportation routes in and out of the state. Bridge tolls are collected only from traffic exiting the state, with the exception of the private Dingman's Ferry Bridge over the Delaware River, which charges a toll in both directions.

It is unlawful for a customer to serve themselves gasoline in New Jersey. It became the last remaining U.S. state where all gas stations are required to sell full-service gasoline to customers at all times in 2016, after Oregon's introduction of restricted self-service gasoline availability took effect.[226]

Newark Liberty International Airport (EWR) is one of the busiest airports in the United States. Operated by the Port Authority of New York and New Jersey, it is one of the three main airports serving the New York metropolitan area, along with John F. Kennedy International Airport and LaGuardia Airport, which are both in Queens, New York. United Airlines is the airport's largest tenant, operating an entire terminal (Terminal C) there, which it uses as one of its primary hubs. FedEx Express operates a large cargo terminal at EWR as well. The adjacent Newark Airport railroad station provides access to Amtrak and NJ Transit trains along the Northeast Corridor Line.

Two smaller commercial airports, Atlantic City International Airport and rapidly growing Trenton-Mercer Airport, also operate in other parts of the state. Teterboro Airport in Bergen County and Millville Municipal Airport in Cumberland County are general aviation airports popular with private and corporate aircraft due to their proximity to New York City and the Jersey Shore, respectively.

NJ Transit operates extensive rail and bus service throughout the state. A state-run corporation, it began with the consolidation of several private bus companies in North Jersey in 1979. In the early 1980s, it acquired Conrail's commuter train operations that connected suburban towns to New York City. Today, NJ Transit has eleven commuter rail lines that run through different parts of the state. Most of the lines end at either Penn Station in New York City or Hoboken Terminal in Hoboken, although some lines serve service to both terminal stations. One line provides service between Atlantic City and Philadelphia.

NJ Transit also operates three light rail systems in the state. The Hudson-Bergen Light Rail connects Bayonne to North Bergen, through Hoboken and Jersey City. The Newark Light Rail is partially underground, and connects downtown Newark with other parts of the city and its suburbs, Belleville and Bloomfield. The River Line connects Trenton, and Camden.

The PATH is a rapid transit system consisting of four lines operated by the Port Authority of New York and New Jersey. It links Hoboken, Jersey City, Harrison, and Newark with New York City. The PATCO Speedline is a rapid transit system that links Camden County to Philadelphia. Both the PATCO and the PATH are two of only five rapid transit systems in the United States to operate 24 hours a day.

Amtrak operates numerous long-distance passenger trains in New Jersey, both to and from neighboring states and around the country. In addition to the Newark Airport connection, other major Amtrak railway stations include Trenton Transit Center, Metropark, and the historic Newark Penn Station.

The Southeastern Pennsylvania Transportation Authority, or SEPTA, has two commuter rail lines that operate into New Jersey. The Trenton Line terminates at the Trenton Transit Center, and the West Trenton Line terminates at the West Trenton Rail Station in Ewing.

AirTrain Newark is a monorail connecting the Amtrak/NJ Transit station on the Northeast Corridor to the airport's terminals and parking lots.

Some private bus carriers still remain in New Jersey. Most of these carriers operate with state funding to offset losses and state owned buses are provided to these carriers, of which Coach USA companies make up the bulk. Other carriers include private charter and tour bus operators that take gamblers from other parts of New Jersey, New York City, Philadelphia, and Delaware to the casino resorts of Atlantic City.

New York Waterway has ferry terminals at Belford, Jersey City, Hoboken, Weehawken, and Edgewater, with service to different parts of Manhattan. Liberty Water Taxi in Jersey City has ferries from Paulus Hook and Liberty State Park to Battery Park City in Manhattan. Statue Cruises offers service from Liberty State Park to the Statue of Liberty National Monument, including Ellis Island. SeaStreak offers services from the Raritan Bayshore to Manhattan, Martha's Vineyard, and Nantucket.

The Delaware River and Bay Authority operates the Cape May–Lewes Ferry on Delaware Bay, carrying both passengers and vehicles between New Jersey and Delaware. The agency also operates the Forts Ferry Crossing for passengers across the Delaware River. The Delaware River Port Authority operates the RiverLink Ferry between the Camden waterfront and Penn's Landing in Philadelphia.

The position of Governor of New Jersey is one of the most powerful in the nation. The governor is elected on a ticket with their lieutenant governor as the only statewide elected executive officials in the state; the governor appoints the entire executive cabinet and judges of the Supreme and Superior Courts. Phil Murphy (D) is the governor. The governor's mansion is Drumthwacket, located in Princeton.

Before 2010, New Jersey was one of the few states without a lieutenant governor. Republican Kim Guadagno was elected the first lieutenant governor of New Jersey on the Republican ticket with Governor Chris Christie and took office on January 19, 2010. The position was created as the result of a Constitutional amendment to the New Jersey State Constitution passed by the voters in 2005. Previously a gubernatorial vacancy would be filled by the president of the New Jersey State Senate as acting governor, thus directing half of the legislative and all of the executive process.

The current version of the New Jersey State Constitution was adopted in 1947. It provides for a bicameral New Jersey Legislature, consisting of an upper house Senate of 40 members and a lower house General Assembly of 80 members. Each of the 40 legislative districts elects one state senator and two Assembly members. Assembly members are elected for a two-year term in all odd-numbered years; state senators are elected in years ending in 1, 3, and 7 and thus serve either four- or two-year terms.

New Jersey is one of only five states that elects its state officials in odd-numbered years (the others are Kentucky, Louisiana, Mississippi, and Virginia). New Jersey holds elections for these offices every four years, in the year following each federal Presidential election year.

The New Jersey Supreme Court[227] consists of a chief justice and six associate justices. All are appointed by the governor with the advice and consent of a majority of the membership of the state senate. Justices serve an initial seven-year term, after which they can be reappointed to serve until age 70.

Most of the day-to-day work in the New Jersey courts is carried out in the Municipal Court, where simple traffic tickets, minor criminal offenses, and small civil matters are heard.

More serious criminal and civil cases are handled by the Superior Court for each county. All Superior Court judges are appointed by the governor with the advice and consent of a majority of the membership of the state senate. Each judge serves an initial seven-year term and can be reappointed to serve until age 70. New Jersey's judiciary is unusual in that it still has separate courts of law and equity, like its neighbor Delaware but unlike most other U.S. states. The New Jersey Superior Court is divided into Law and Chancery Divisions at the trial level; the Law Division hears both criminal cases and civil lawsuits where the plaintiff's primary remedy is damages, while the Chancery Division hears family cases, civil suits where the plaintiff's primary remedy is equitable relief, and probate trials.

The Superior Court also has an Appellate Division, which functions as the state's intermediate appellate court. Superior Court judges are assigned to the Appellate Division by the Chief Justice.

There is also a Tax Court, which is a court of limited jurisdiction. Tax Court judges hear appeals of tax decisions made by County Boards of Taxation. They also hear appeals on decisions made by the director of the Division of Taxation on such matters as state income, sales and business taxes, and homestead rebates. Appeals from Tax Court decisions are heard in the Appellate Division of Superior Court. Tax Court judges are appointed by the governor for initial terms of seven years, and upon reappointment are granted tenure until they reach the mandatory retirement age of 70. There are 12 Tax Court judgeships.

New Jersey is divided into 21 counties; 13 date from the colonial era. New Jersey was completely divided into counties by 1692; the present counties were created by dividing the existing ones; most recently Union County in 1857.[228] New Jersey was formerly the only state in the nation where elected county officials were called "freeholders". Elected county officials are now called county commissioners as of bill S855 signed by Governor Murphy on August 8, 2020. The county commissioners govern each county as part of its own Board of Chosen County Commissioners[229] The number of county commissioners in each county is determined by referendum, and must consist of three, five, seven or nine members.

Depending on the county, the executive and legislative functions may be performed by the Board of County Commissioners or split into separate branches of government. In 16 counties, the County Commissioners perform both legislative and executive functions on a commission basis, with each commissioner assigned responsibility for a department or group of departments. In the other five counties (Atlantic, Bergen, Essex, Hudson and Mercer), there is a directly elected County Executive who performs the executive functions while the commissioners retain a legislative and oversight role. In counties without an Executive, a County Administrator (or County Manager) may be hired to perform day-to-day administration of county functions.[230]

New Jersey currently has 564 municipalities; the most recent dissolution of a municipality was when Pine Valley merged into Pine Hill on January 1, 2022. Unlike other states, all New Jersey land is part of a municipality. In 2008, Governor Jon Corzine proposed cutting state aid to all towns under 10,000 people, to encourage mergers to reduce administrative costs.[231] In May 2009, the Local Unit Alignment Reorganization and Consolidation Commission began a study of about 40 small communities in South Jersey to decide which ones might be good candidates for consolidation.[232]

Starting in the 20th century, largely driven by reform-minded goals, a series of six modern forms of government was implemented. This began with the Walsh Act, enacted in 1911 by the New Jersey Legislature, which provided for a three- or five-member commission elected on a non-partisan basis. This was followed by the 1923 Municipal Manager Law, which offered a non-partisan council, provided for a weak mayor elected by and from the members of the council, and introduced a Council-manager government structure with an appointed manager responsible for the day-to-day administration of municipal affairs.

The Faulkner Act, originally enacted in 1950 and substantially amended in 1981, offers four basic plans: Mayor-Council, Council-Manager, Small Municipality, and Mayor-Council-Administrator. The act provides many choices for communities with a preference for a strong executive and professional management of municipal affairs and offers great flexibility in allowing municipalities to select the characteristics of its government: the number of seats on the council; seats selected at-large, by wards, or through a combination of both; staggered or concurrent terms of office; and a mayor chosen by the council or elected directly by voters. Most large municipalities and a majority of New Jersey's residents are governed by municipalities with Faulkner Act charters. Municipalities can also formulate their own unique form of government and operate under a Special Charter with the approval of the New Jersey Legislature.[233]

While municipalities retain their names derived from types of government, they may have changed to one of the modern forms of government, or further in the past to one of the other traditional forms, leading to municipalities with formal names quite baffling to the general public. For example, though there are four municipalities that are officially of the village type, Loch Arbour is the only one remaining with the village form of government. The other three villages—Ridgefield Park (now with a Walsh Act form), Ridgewood (now with a Faulkner Act Council-Manager charter) and South Orange (now operates under a Special Charter)—have all migrated to other non-village forms.[234]

Socially, New Jersey is considered one of the more liberal states in the nation. Polls indicate that 60% of the population are self-described as pro-choice, although a majority are opposed to late trimester and intact dilation and extraction and public funding of abortion.[235][236] In a 2009 Quinnipiac University Polling Institute poll, a plurality supported same-sex marriage 49% to 43% opposed.[237] On October 18, 2013, the New Jersey Supreme Court rendered a provisional, unanimous (7–0) order authorizing same-sex marriage in the state, pending a legal appeal by Governor Chris Christie,[238] who then withdrew this appeal hours after the inaugural same-sex marriages took place on October 21, 2013.[239]

New Jersey also has some of the most stringent gun control laws in the U.S. These include bans on assault firearms, hollow-nose bullets and slingshots. No gun offense in New Jersey is graded less than a felony. BB guns and black-powder guns are all treated as modern firearms. New Jersey does not recognize out-of-state gun licenses and aggressively enforces its own gun laws.[240]

New Jersey is a Democratic stronghold. New Jersey Democrats have majority control of both houses of the New Jersey Legislature (Senate, 24–16, and Assembly, 46-34), a 10–2 split of the state's twelve seats in the U.S. House of Representatives, and both U.S. Senate seats. There have been recent Republican governors, however: Christine Todd Whitman won election in 1993 and 1997 and Chris Christie in 2009 and 2013.

In federal elections, the state leans heavily towards the Democratic Party, having last voted for a Republican for president in 1988. New Jersey was a crucial swing state in the elections of 1960, 1968, and 1992. The last elected Republican to hold a Senate seat from New Jersey was Clifford P. Case in 1979. Newark Mayor Cory Booker was elected in October 2013 to join Robert Menendez to make New Jersey the first state with concurrently serving black and Latino U.S. senators.[241]

The state's Democratic strongholds include Camden County, Essex County (the state's most Democratic county—it includes Newark, the state's largest city), Hudson County (the second-strongest Democratic county, including Jersey City, the state's second-largest city); Mercer County (especially around Trenton and Princeton), Middlesex County, and Union County (including Elizabeth, the state's fourth-largest city).[242] Other suburban counties, especially Bergen County and Burlington County, had the majority of votes go to the Democratic Party.

The northwestern and southeastern counties of the state are reliably Republican: Republicans have support along the coast in Ocean County and in the mountainous northwestern part of the state, especially Hunterdon County, Sussex County, and Warren County.

To be eligible to vote in a U.S. election, all New Jerseyans are required to start their residency in the state 30 days prior to an election and register 21 days prior to election day.[243]

On December 17, 2007, Governor Jon Corzine signed into law a bill that would eliminate the death penalty in New Jersey. New Jersey was the first state to pass such legislation since Iowa and West Virginia eliminated executions in 1965.[244] Corzine also signed a bill that would downgrade the Death Row prisoners' sentences from "Death" to "Life in Prison with No Parole".[245]
