Government of New York City in the context of "Unicameralism"

Manhattan is the most densely populated and geographically smallest of the five boroughs of New York City. Coextensive with New York County, Manhattan is the smallest county by area in the U.S. state of New York. Located almost entirely on Manhattan Island near the southern tip of the state, Manhattan is centrally located in the Northeast megalopolis and the urban core of the New York metropolitan area. Manhattan serves as New York City's economic and administrative center and has been described as the cultural, financial, media, and entertainment capital of the world.

Present-day Manhattan was originally part of Lenape territory. European settlement began with the establishment of a trading post by Dutch colonists in 1624 on Manhattan Island; the post was named New Amsterdam in 1626. The territory came under English control in 1664 and was renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York, based in present-day Lower Manhattan, served as the capital of the United States from 1785 until 1790. The Statue of Liberty in New York Harbor greeted millions of arriving immigrants in the late 19th century and is a world symbol of the United States and its ideals. Manhattan became a borough during the consolidation of New York City in 1898, and houses New York City Hall, the seat of the city's government. Harlem in Upper Manhattan became the center of what is now known as the cultural Harlem Renaissance in the 1920s. The Stonewall Inn in Greenwich Village, part of the Stonewall National Monument, is considered the birthplace in 1969 of the modern gay-rights movement, cementing Manhattan's central role in LGBTQ culture. Manhattan was the site of the original World Trade Center, which was destroyed during the September 11 terrorist attacks in 2001.

The New York City Subway is a rapid transit system in New York City, serving four of the city's five boroughs: Manhattan, Brooklyn, Queens, and the Bronx. It is owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the state-run Metropolitan Transportation Authority (MTA). Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the second-most stations after the Beijing Subway, with 472 stations in operation (423, if stations connected by transfers are counted as single stations).

The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the ninth-busiest rapid transit rail system in the world. The subway carried 2,040,132,000 unlinked, non-unique riders in 2024. Daily ridership has been calculated since 1985; the record, over 6.2 million, was set on October 29, 2015.

Central Park is an urban park between the Upper West Side and Upper East Side neighborhoods of Manhattan in New York City, and the first landscaped park in the United States. It is the sixth-largest park in the city, containing 843 acres (341 ha), and the most visited urban park in the United States, with an estimated 42 million visitors annually as of 2016. Central Park is owned by the New York City Department of Parks and Recreation but has been managed by the Central Park Conservancy since 1998 under a contract with the government of New York City in a public–private partnership. The conservancy, a non-profit organization, sets Central Park's annual operating budget and is responsible for care of the park.

The creation of a large park in Manhattan was first proposed in the 1840s, and a 778-acre (315 ha) park approved in 1853. In 1858, landscape architects Frederick Law Olmsted and Calvert Vaux won a design competition for the park with their "Greensward Plan". Construction began in 1857; existing structures, including a majority-Black settlement named Seneca Village, were seized through eminent domain and razed. The park's first areas were opened to the public in late 1858. Additional land at the northern end of Central Park was purchased in 1859, and the park was completed in 1876. After a period of decline in the early 20th century, New York City parks commissioner Robert Moses started a program to clean up Central Park in the 1930s. The Central Park Conservancy, created in 1980 to combat further deterioration in the late 20th century, refurbished many parts of the park starting in the 1980s.

Staten Island (/ˈstætən/ STAT-ən) is the southernmost of the five boroughs of New York City, coextensive with Richmond County and situated at the southernmost point of New York. The borough is separated from the adjacent state of New Jersey by the Arthur Kill and the Kill Van Kull and from the rest of New York by New York Bay. With a population of 495,747 in the 2020 Census, Staten Island is the least populated New York City borough but the third largest in land area at 58.5 sq mi (152 km); it is also the least densely populated and most suburban borough in the city.

A home to the Lenape Native Americans, the island was settled by Dutch colonists in the 17th century. It was one of the 12 original counties of New York state. Staten Island was consolidated with New York City in 1898. It was formerly known as the Borough of Richmond until 1975, when its name was changed to Borough of Staten Island. Staten Island has sometimes been called "the forgotten borough" by inhabitants who feel neglected by the city government and the media. It has also been referred to as the "borough of parks" due to its 12,300 acres of protected parkland and over 170 parks.

Lower Manhattan, also known as Downtown Manhattan, is the southernmost part of the New York City borough of Manhattan. The area is the historical birthplace of New York City and in the 17th and 18th centuries composed the entirety of the city. Lower Manhattan serves as the seat of government of both Manhattan and the entire City of New York because there are no municipally defined boundaries for the area. A precise population cannot be quoted, but several sources have suggested that it was one of the fastest-growing locations in New York City between 2010 and 2020, related to the influx of young adults and significant development of new housing units.

Despite various definitions of Lower Manhattan, they generally include all of Manhattan Island south of 14th Street, with the Bowling Green and the Battery near the southern end. Anchored by Wall Street and the Financial District in Lower Manhattan, New York City is the leading global center for finance and fintech. The Financial District houses the New York Stock Exchange, the Federal Reserve Bank of New York, and other major financial institutions. A center of culture and tourism, Lower Manhattan is home to many of New York City's most iconic structures, including New York City Hall, the Woolworth Building, the Stonewall Inn, the Bull of Wall Street, and One World Trade Center, the tallest skyscraper in the Western Hemisphere.

New York City Hall is the seat of New York City government, located at the center of City Hall Park in the Civic Center area of Lower Manhattan, between Broadway, Park Row, and Chambers Street. Constructed from 1803 to 1812, the building is the oldest city hall in the United States that still houses its original governmental functions. The building houses the office of the Mayor of New York City and the chambers of the New York City Council. While the Mayor's Office is in the building, the staff of thirteen municipal agencies under mayoral control are located in the nearby Manhattan Municipal Building, one of the largest government buildings in the world, with many others housed in various buildings in the immediate vicinity.

New York City Hall is a National Historic Landmark and is listed on the National Register of Historic Places. The New York City Landmarks Preservation Commission designated both City Hall's exterior and interior as official city landmarks in 1966 and 1976, respectively.

This is a list of the 100 most populous of the 3,144 counties in the United States based on the national decennial US census conducted on April 1, 2020, and vintage Census population estimates for July 1, 2024.

Many of the counties on the list include major cities or metropolitan areas in all parts of the United States. Seven of the listed counties have consolidated city and county government, namely the City and County of Honolulu, Metropolitan Government of Nashville and Davidson County, Tennessee, City and County of Philadelphia, City and County of San Francisco, City of Jacksonville and Duval County, Indianapolis and Marion County, and City and County of Denver. Kings County, Queens County, New York County, Bronx County, and Richmond County are coterminous with the respective boroughs of New York City; they fall under the jurisdiction of the combined Government of New York City. Independent cities are not counted.

The New York City Department of Parks and Recreation, also called the Parks Department or NYC Parks, is the department of the government of New York City responsible for maintaining the city's parks system, preserving and maintaining the ecological diversity of the city's natural areas, and furnishing recreational opportunities for city's residents and visitors.

NYC Parks maintains more than 1,700 public spaces, including parks, playgrounds and recreational facilities, across the city's five boroughs. It is responsible for over 1,000 playgrounds, 800 playing fields, 550 tennis courts, 35 major recreation centers, 66 pools, 14 miles (23 km) of beaches, and 13 golf courses, as well as 7 nature centers, 6 ice skating rinks, over 2,000 greenstreets, and 4 major stadiums. NYC Parks also cares for park flora and fauna, community gardens, 23 historic houses, over 1,200 statues and monuments, and more than 2.5 million trees. The total area of the properties maintained by the department is over 30,000 acres (120 km). The largest single component of parkland maintained by the department is the 2,765-acre (1,119 ha) Pelham Bay Park in the Bronx. Other large parks administered by NYC Parks include Central Park in Manhattan, Prospect Park in Brooklyn, Van Cortlandt Park in the Bronx, Flushing Meadows–Corona Park in Queens, and the Staten Island Greenbelt.

The Central Park Conservancy is an American private, nonprofit park conservancy that manages New York City's Central Park under a contract with the government of New York City and NYC Parks. The conservancy employs most maintenance and operations staff in the park. It effectively oversees the work of both the private and public employees under the authority of the publicly appointed Central Park administrator, who reports to the parks commissioner and the conservancy's president.

The Central Park Conservancy was founded in 1980 in the aftermath of Central Park's decline in the 1960s and 1970s. Initially devoted to fundraising for projects to restore and improve the park, it took over the park's management duties in 1998. The organization has overseen the investment of more than $1 billion toward the restoration and enhancement of Central Park since its founding. With an endowment of over $200 million, consisting of contributions from residents, corporations, and foundations, the Conservancy raises the Park’s nearly $74 million annual operating budget and is responsible for all basic care of the park. The Conservancy also provides maintenance support and staff training programs for other public parks in New York City, and has assisted with the development of new parks, such as the High Line and Brooklyn Bridge Park.
