Jersey City is the second-most populous city in the U.S. state of New Jersey, after Newark. It is the county seat of Hudson County, and is the county's most populous city and its largest (by area). As of the 2020 United States census, the city's population was 292,449, an increase of 44,852 (+18.1%) from the 2010 census count of 247,597, in turn an increase of 7,542 (+3.1%) from the 240,055 enumerated at the 2000 census. The Population Estimates Program calculated a population of 291,657 for 2023, making it the 72nd-most populous municipality in the nation.

Constituting part of the New York metropolitan area, Jersey City is bounded on the east by the Hudson River and Upper New York Bay and on the west by the Hackensack River and Newark Bay. A port of entry, with 30.7 miles (49.4 km) of waterfront and extensive rail infrastructure and connectivity, the city is an important transportation terminus and distribution and manufacturing center for the Port of New York and New Jersey. The Holland Tunnel, PATH mass transit system, and NY Waterway ferry service connect across the Hudson River with Manhattan. Redevelopment of the Jersey City waterfront has made the city one of the largest centers of banking and finance in the United States and has led to the district and city being nicknamed Wall Street West. Jersey City's proximity to Manhattan and its own financially based economy have propelled apartment rents in the city to some of the highest in the United States.

The land that is now Jersey City was inhabited by the Lenape, a collection of Native American tribes (later called Delaware Indian). In 1609, Henry Hudson, seeking an alternate route to East Asia, anchored his small vessel Halve Maen (English: Half Moon) at Sandy Hook, Harsimus Cove and Weehawken Cove, and elsewhere along what was later named the North River. After spending nine days surveying the area and meeting its inhabitants, he sailed as far north as Albany. The contemporary flag of the city is a variation on the Prince's Flag from the Netherlands. The stripes are blue, white and yellow, with the center of the flag showing the city seal, depicting Hudson's ship, the Half Moon, and other modern vessels.

By 1621, the Dutch West India Company was organized to manage this new territory and in June 1623, New Netherland became a Dutch province, with headquarters in New Amsterdam. Michael Reyniersz Pauw received a land grant as patroon on the condition that he would establish a settlement of not fewer than fifty persons within four years. He chose the west bank of the Hudson River and purchased the land from the Lenape. This grant is dated November 22, 1630, and is the earliest known conveyance for what are now Hoboken and Jersey City. Pauw, however, was an absentee landlord who neglected to populate the area and was obliged to sell his holdings back to the Company in 1633. That year, a house was built at Communipaw for Jan Evertsen Bout, superintendent of the colony, which had been named Pavonia (the Latinized form of Pauw's name, which means "peacock"). Shortly after, another house was built at Harsimus Cove and became the home of Cornelius Van Vorst, who had succeeded Bout as superintendent, and whose family would become influential in the development of the city. Relations with the Lenape deteriorated, in part because of the colonialist's mismanagement and misunderstanding of the indigenous people, and led to series of raids and reprisals and the virtual destruction of the settlement on the west bank. During Kieft's War, approximately eighty Lenapes were killed by the Dutch in a massacre at Pavonia on the night of February 25, 1643.

Scattered communities of farmsteads characterized the Dutch settlements at Pavonia: Communipaw, Harsimus, Paulus Hook, Hoebuck, Awiehaken, Pamrapo, and other lands "behind Kill van Kull". The village of Bergen (located inside a palisaded garrison) was established on what is now Bergen Square in 1660 and officially chartered on September 5, 1661, as the state's first local civil government. As a result, it is regarded as the first permanent settlement and oldest municipality in what would become the state of New Jersey. In addition, the oldest surviving houses in Jersey City are of Dutch origin including the Newkirk House (1690), the Van Vorst Farmhouse (1740), and the Van Wagenen House (1740).

In 1804, Alexander Hamilton, now a private citizen, was focused on increasing manufacturing in the greater New York City area. To that end, he helped to create the Associates of the Jersey Company which would lay the groundwork for modern Jersey City through private development. The consortium behind the company were predominantly Federalists who, like Hamilton, had been swept out of power in the election of 1800 by Thomas Jefferson and other Democratic-Republicans. Large tracts of land in Paulus Hook were purchased by the company with the titles owned by Anthony Dey, who was from a prominent old Dutch family, and his two cousins, Colonel Richard Varick, the former mayor of New York City (1789–1801), and Jacob Radcliff, a Justice of the New York Supreme Court who would later become mayor of New York City (twice) from 1810 to 1811 and again from 1815 to 1818. They laid out the city squares and streets that still characterize the neighborhood, giving them names also seen in Lower Manhattan or after war heroes (Grove, Varick, Mercer, Wayne, Monmouth and Montgomery among them).

Despite Hamilton's untimely death in August 1804, the Association carried on, though the enterprise was mired in a legal dispute between New York City and the state of New Jersey over who owned the waterfront. The unresolved dispute would continue until the Treaty of 1834 where New York City formally ceded control of Jersey City to New Jersey. Over that time though, the Jersey Company applied to the New Jersey Legislature to incorporate the Town of Jersey. The legislature enacted "An Act to incorporate the City of Jersey, in the County of Bergen" on January 28, 1820. Under the provision, five freeholders (including Varick, Dey, and Radcliff) were to be chosen as "the Board of Selectmen of Jersey City", thereby establishing the first governing body of the emerging municipality. The city was reincorporated on January 23, 1829, and again on February 22, 1838, at which time it became completely independent of North Bergen and was given its present name. On February 22, 1840, it became part of the newly created Hudson County.

During the 19th century, former slaves reached Jersey City on one of the four routes of the Underground Railroad that led to the city.

Soon after the Civil War, the idea arose of uniting all of the towns of Hudson County east of the Hackensack River into one municipality. A bill was approved by the state legislature on April 2, 1869, with a special election to be held on October 5, 1869. An element of the bill provide that only contiguous towns could be consolidated. While a majority of the voters across the county approved the merger, the only municipalities that had approved the consolidation plan and that adjoined Jersey City were Hudson City and Bergen City. The consolidation began on March 17, 1870, taking effect on May 3, 1870. Three years later the present outline of Jersey City was completed when Greenville agreed to merge into the Greater Jersey City.

In the late 1880s, three passenger railroad terminals opened in Jersey City next to the Hudson River (Pavonia Terminal, Exchange Place and Communipaw). Tens of millions of immigrants passed through these stations as they made their way westward from Ellis Island into the United States. The railroads transformed the geography of the city by building the Erie Cut as well as several large freight rail yards.

Jersey City was a dock and manufacturing town for much of the 19th and 20th centuries. Much like New York City, Jersey City has always been a destination for new immigrants to the United States. In its heyday before World War II, German, Irish, and Italian immigrants found work at Colgate, Chloro or Dixon Ticonderoga. In 1908, the first permanent disinfection system for drinking water in the U.S. was installed on the water supply for the city by John L. Leal. The Hudson Tubes opened in 1911, allowing passengers to take the train to Manhattan as an alternative to the extensive ferry system. The Black Tom explosion occurred on July 30, 1916, as an act of sabotage on American ammunition supplies by German agents to prevent the materials from being used by the Allies in World War I.

From 1917 to 1947, Jersey City was governed by Mayor Frank Hague. Originally elected as a candidate supporting reform in governance, the Jersey City History website says his name is "synonymous with the early twentieth century urban American blend of political favoritism and social welfare known as bossism". Hague ran the city with an iron fist while, at the same time, molding governors, United States senators, and judges to his whims. Boss Hague was known to be loud and vulgar, but dressed in a stylish manner, earning him the nickname "King Hanky-Panky". In his later years in office, Hague would often dismiss his enemies as "reds" or "commies". Hague lived like a millionaire, despite having an annual salary that never exceeded $8,500. He was able to maintain a fourteen-room duplex apartment in Jersey City, a suite at the Plaza Hotel in Manhattan, and a palatial summer home in the seaside community of Deal, and travel to Europe yearly in the royal suites of the best ocean liners.

After Hague's retirement from politics, a series of mayors including John V. Kenny, Thomas J. Whelan and Thomas F. X. Smith attempted to take control of Hague's organization, usually under the mantle of political reform. None were able to duplicate the level of power held by Hague, but the city and the county remained notorious for political corruption for years. By the 1970s the city experienced a period of urban decline that saw many of its wealthy residents leave for the suburbs, due to rising crime, civil unrest, political corruption, and economic hardship. From 1950 to 1980, Jersey City lost 75,000 residents, and from 1975 to 1982, it lost 5,000 jobs, or 9% of its workforce.

Beginning in the 1980s, development of the waterfront in an area previously occupied by rail yards and factories helped to stir the beginnings of a renaissance for Jersey City. The rapid construction of numerous high-rise buildings increased the population and led to the development of the Exchange Place financial district, also known as "Wall Street West", one of the largest financial centers in the United States. Large financial institutions such as UBS, Goldman Sachs, Chase Bank, Citibank, and Merrill Lynch occupy prominent buildings on the Jersey City waterfront, some of which are among the tallest buildings in New Jersey. Simultaneous to this building boom, the light-rail network was developed. With 18,000,000 square feet (1,700,000 m) of office space as of 2011, it has the nation's 12th-largest downtown.

City Ordinance 13.097, passed in October 2013, requires employers with ten or more employees to offer up to five paid sick days a year. The bill impacts all businesses employing workers who work at least 80 hours a calendar year in Jersey City.

Jersey City is the seat of Hudson County and the second-most-populous city in New Jersey. According to the United States Census Bureau, the city had a total area of 21.13 square miles (54.74 km), including 14.74 square miles (38.19 km) of land and 6.39 square miles (16.55 km) of water (30.24%). As of the 1990 census, it had the smallest land area of the 100 most populous cities in the United States.

Jersey City is bordered to the east by the Hudson River, to the north by Secaucus, North Bergen, Union City and Hoboken, to the west, across the Hackensack River, by Kearny and Newark, and to the south by Bayonne.

Jersey City includes most of Ellis Island (the parts awarded to New Jersey by the 1998 U.S. Supreme Court in the case of New Jersey v. New York). Liberty Island is surrounded by Jersey City waters in the Upper New York Bay. Given its proximity and various rapid transit connections to Manhattan, Jersey City (along with Hudson County as a whole) is sometimes referred to as New York City's sixth borough.

Jersey City (and most of Hudson County) is located on the peninsula known as Bergen Neck, with a waterfront on the east at the Hudson River and New York Bay and on the west at the Hackensack River and Newark Bay. Its north–south axis corresponds with the ridge of Bergen Hill, the emergence of the Hudson Palisades. The city is the site of some of the earliest European settlements in North America, which grew into each other rather than expanding from a central point. This growth and the topography greatly influenced the development of the sections of the city and its various neighborhoods.

The city is divided into six wards.

Bergen-Lafayette, formerly Bergen City, New Jersey, lies between Greenville to the south and McGinley Square to the north, while bordering Liberty State Park and Downtown to the east and the West Side neighborhood to the west. Communipaw Avenue, Bergen Avenue, Martin Luther King Drive, and Ocean Avenue are main thoroughfares. The former Jersey City Medical Center complex, a cluster of Art Deco buildings on a rise in the center of the city, has been converted into residential complexes called The Beacon. Completed in 2016 at a cost of $38 million, (~$47.3 million in 2023) Berry Lane Park is located along Garfield Avenue in the northern section of Bergen-Lafayette; covering 17.5 acres (7.1 ha), it is the largest municipal park in Jersey City.

Downtown Jersey City is the area from the Hudson River westward to the Newark Bay Extension of the New Jersey Turnpike (Interstate 78) and the New Jersey Palisades; it is also bounded by Hoboken to the north and Liberty State Park to the south.

Historic Downtown is an area of mostly low-rise buildings to the west of the waterfront that is highly desirable due to its proximity to local amenities and Manhattan. It includes the neighborhoods of Van Vorst Park and Hamilton Park, which are both square parks surrounded by brownstones. This historic downtown also includes Paulus Hook, the Village and Harsimus Cove neighborhoods. Newark Avenue & Grove Street, are the main thoroughfares in Downtown Jersey City, both have seen a lot of development and the surrounding neighborhoods have many stores and restaurants. The Grove Street PATH station is in the process of being renovated and a number of new residential buildings are being built around the stop, including a proposed 50-story building at 90 Columbus. Historic Downtown is home to many cultural attractions including the Jersey City Museum, the Hudson and Manhattan Railroad Powerhouse (planned to become a museum and artist housing) and the Harsimus Stem Embankment along Sixth Street, which a citizens' movement is working to turn into public parkland that would be modeled after the High Line in Manhattan.

Newport and Exchange Place are redeveloped waterfront areas consisting mostly of residential towers, hotels and office buildings that are among the tallest buildings in the city. Newport is a planned mixed-use community, built on the old Erie Lackawanna Railway yards, made up of residential rental towers, condominiums, office buildings, a marina, schools, restaurants, hotels, Newport Centre Mall, a waterfront walkway, transportation facilities, and on-site parking for more than 15,000 vehicles. Newport had a hand in the renaissance of Jersey City although, before ground was broken, much of the downtown area had already begun a steady climb (much like Hoboken).

The Heights or Jersey City Heights is a district in the north end of Jersey City atop the New Jersey Palisades overlooking Hoboken to the east and Croxton in the Meadowlands to the west. Previously the city of Hudson City, The Heights was incorporated into Jersey City in 1869. The southern border of The Heights is generally considered to be north of Bergen Arches and the Depressed Highway, while Paterson Plank Road in Washington Park is its main northern boundary. Transfer Station is just over the city line. Its postal area ZIP Code is 07307. The Heights mostly contains two- and three-family houses and low rise apartment buildings, and is similar to North Hudson architectural style and neighborhood character.

Journal Square is a mixed-use district. The square was created in 1923, creating a broad intersection with Hudson Boulevard which itself had been widened in 1908. McGinley Square is located in close proximity to Journal Square, and has been described as an extension of it.

Greenville is on the south end of Jersey City. In the 2010s, the neighborhood underwent a revitalization. Considered an affordable neighborhood in the New York City area, a number of Ultra-Orthodox Jews and young families purchased homes and built a substantial community there, attracted by housing that costs less than half of comparable homes in New York City. In a December 2019 shooting incident, three bystanders were killed in a kosher market in Greenville. The two assailants, who had earlier killed a police detective, were also shot and killed.

The West Side borders Greenville to the south and the Hackensack River to the west; it is also bounded to the east and north by Bergen-Lafayette and the broader Journal Square area, including McGinley Square. It consists of various diverse areas on both sides of West Side Avenue, one of Jersey City's leading shopping streets.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters. According to the Köppen climate classification system, Jersey City has a humid subtropical climate similar to its parallel cities like Newark and New York City.

As of the 2020 census, Jersey City had a population of 292,449, and a population density of 19,835.1 inhabitants per square mile (7,658.4/km) an increase of 44,852 residents (18.1%) from its 2010 census population of 247,597. Since it was believed the earlier population was under-counted, the 2010 census was anticipated with the possibility that Jersey City might become the state's most populated city, surpassing Newark. The city hired an outside firm to contest the results, citing the fact that development in the city between 2000 and 2010 substantially increased the number of housing units and that new populations may have been under-counted by as many as 30,000 residents based on the city's calculations. Preliminary findings indicated that 19,000 housing units went uncounted.

Per the American Community Survey's 2014–2018 estimates, Jersey City's age distribution was 7.7% of the population under 5, 13.2% between 6–18, 69% – from 19 to 64, and 10.1% who were 65 years of age or older. The median age 34.2 years. Females made up 50.8% of the population and there were 100.1 males per 100 females. 86.5% of the population graduated high school, while 44.9% of the population had a bachelor's degree or higher. 7.1% of residents under 65 were disabled, while 15.9% of residents live without health insurance.

There were 110,801 housing units and 102,353 households in 2018. The average household size was 2.57. The average per capita income was $36,453, and the median household income was $62,739. 18.7% of residents lived below the poverty line. 67.9% of residents 16+ were within the civilian labor force. The mean travel time to work for residents was 36.8 minutes. 28.6% of housing units are owner-occupied, with the median value of the homes being $344,200. The median gross rent in the city was $1,271.

Jersey City has been called "one of the most diverse cities in the world". The city is a major port of entry for immigration to the United States and a major employment center at the approximate core of the New York City metropolitan area; and given its proximity to Manhattan, Jersey City has evolved a globally cosmopolitan ambiance of its own, demonstrating a robust and growing demographic and cultural diversity concerning metrics including "nationality, religion, race, and domiciliary partnership."

Jersey City, New Jersey – Racial and ethnic composition
Note: the US Census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category. Hispanics/Latinos may be of any race.

The U.S. Census accounts for race by two methodologies. "Race alone" and "Race alone less Hispanics" where Hispanics are delineated separately as if a separate race.

According to the 2020 U.S. Census, the racial makeup (including Hispanics in the racial counts) was 27.32% (79,905) White alone, 19.87% (58,103) Black alone, 0.66% (1,916) Native American alone, 28.01% (81,903) Asian alone, 0.06% (178) Pacific Islander alone, 14.35% (41,970) Other Race alone, and 9.74% (28,474) Multiracial or Mixed Race.

According to the 2020 U.S. Census, the racial and ethnic makeup (where Hispanics are excluded from the racial counts and placed in their own category) was 23.81% (69,624) White alone (non-Hispanic), 18.53% (54,199) Black alone (non-Hispanic), 0.22% (638) Native American alone (non-Hispanic), 27.84% (81,425) Asian alone (non-Hispanic), 0.03% (101) Pacific Islander alone (non-Hispanic), 1.44% (4,204) Other Race alone (non-Hispanic), 3.24% (9,481) Multiracial or Mixed Race (non-Hispanic), and 24.89% (72,777) Hispanic or Latino.

There were an estimated 55,493 non-Hispanic whites in Jersey City, according to the 2013–2017 American Community Survey, representing a 4.2% increase from 53,236 non-Hispanic whites enumerated in the 2010 United States census.

An estimated 63,788 African Americans resided in Jersey City, or 24.0% of the city's population in 2017, representing a slight decrease from 64,002 African Americans enumerated in the 2010 United States census. This is in contrast with Hudson County overall, where there were an estimated 84,114 African Americans, according to the 2013–2017 American Community Survey, representing a 2.3% increase from 83,925 African Americans enumerated in the county in the 2010 United States census. However, modest growth in the African immigrant population, most notably the growing Nigerian American and Kenyan American populations in Jersey City, is partially offsetting the decline in the city's American-born black population, which as a whole has been experiencing an exodus from northern New Jersey to the Southern United States. Approximately 76,637 Latino and Hispanic Americans lived in Jersey City, composing 28.8% of the population in 2017, representing a 12.3% increase from 68,256 Latino or Hispanic Americans enumerated in the 2010 United States census. Stateside Puerto Ricans, making up a third of the city's Latin American or Hispanic population, constituted the largest Hispanic group in Jersey City. While Cuban Americans are not as highly concentrated in Jersey City as they are in northern Hudson County, Jersey City has hosted the annual Cuban Parade and Festival of New Jersey at Exchange Place on its downtown waterfront since it was established in 2001.

An estimated 67,526 Asian Americans live in Jersey City, constituting 25.4% of the city's population, representing a 15.2% increase from 58,595 Asian Americans enumerated in the 2010 United States census.

India Square, also known as "Little India" or "Little Bombay", home to the highest concentration of Asian Indians in the Western Hemisphere, is a rapidly growing Indian American ethnic enclave in Jersey City. Indian Americans constituted 10.9% of the overall population of Jersey City in 2010, the highest proportion of any major U.S. city. India Square has been home to the largest outdoor Navratri festivities in New Jersey as well as several Hindu temples; while an annual, color-filled spring Holi festival has taken place in Jersey City since 1992, centered upon India Square and attracting significant participation and international media attention. In 2017 there were an estimated 31,578 Indian Americans in Jersey City, representing a 16.5% increase from 27,111 Indian Americans enumerated in the 2010 United States census.

Filipino Americans, numbering 16,610 residents, made up 6.2% of Jersey City's population in 2017. The Five Corners district serves as a prominent Little Manila of Jersey City, being home to a thriving Filipino community that forms the second-largest Asian-American subgroup in the city. A variety of Filipino restaurants, shippers and freighters, doctors' offices, bakeries, stores, and even an office of The Filipino Channel have made Newark Avenue their home in recent decades. The largest Filipino-owned grocery store on the East Coast, Phil-Am Food, has been established on the avenue since 1973. An array of Filipino-owned businesses can also be found in the West Side section of the city, where many residents are of Filipino descent. In 2006, Red Ribbon Bakeshop, one of the Philippines' most famous food chains, opened its first branch on the East Coast: a new pastry outlet in Jersey City. Manila Avenue in Downtown Jersey City was named for the Philippine capital city because of the many Filipinos who built their homes on the street during the 1970s. A memorial dedicated to the Filipino-American veterans of the Vietnam War was built in a small square on Manila Avenue. A park and statue dedicated to Jose P. Rizal, a national hero of the Philippines, are also located in Downtown Jersey City. Furthermore, Jersey City hosts the annual Philippine–American Friendship Day Parade, an event that occurs yearly on the last Sunday in June. The City Hall of Jersey City raises the Philippine flag in correlation with this event and as a tribute to the contributions of the local Filipino community. The city's annual Santacruzan procession has taken place since 1977 along Manila Avenue.

Behind English and Spanish, Tagalog is the third-most-common language spoken in Jersey City.

Jersey City was home to an estimated 9,379 Chinese Americans in 2017, representing a notably rapid growth of 66.2% from the 5,643 Chinese Americans enumerated in the 2010 United States census. Chinese nationals have also been obtaining EB-5 immigrant visas by investing US$500,000 apiece in new Downtown Jersey City residential skyscrapers.

New Jersey's largest Vietnamese American population resides in Jersey City. There were an estimated 1,813 Vietnamese Americans in Jersey City, according to the 2013–2017 American Community Survey, representing a 12.8% increase from 1,607 Vietnamese Americans enumerated in the 2010 United States census.

Arab Americans numbered an estimated 18,628 individuals in Hudson County per the 2013–2017 American Community Survey, representing 2.8% of the county's total population. Arab Americans are the second- highest percentage in New Jersey after Passaic County. Arab Americans are most concentrated in Jersey City, led by Egyptian Americans, including the largest population of Coptic Christians in the United States.
