The Bronx

Bronx is the northernmost of the five boroughs of New York City. It is also known as Bronx County, the last of the 62 counties of New York State to be incorporated. Located north of Manhattan and Queens, and south of Westchester County, the Bronx is the only borough that is located primarily on the mainland (a very small portion of Manhattan is located on the mainland named Marble Hill). The Bronx's population is 1,400,761 according to the 2010 United States Census. The borough has a land area of 42 square miles (109 km2), making it the fourth most populated of the five boroughs, the fourth-largest in land area, and the third-highest in density of population.

Bronx is divided by the Bronx River into a hillier section in the west, closer to Manhattan, and the flatter East Bronx, closer to Long Island. The West Bronx was annexed to New York City (then largely confined to Manhattan) in 1874, and the areas east of the Bronx River in 1895. The Bronx first assumed a distinct legal identity when it became a borough of Greater New York in 1898. Bronx County, with the same boundaries as the borough, was separated from New York County (afterwards coextensive with the Borough of Manhattan) as of January 1, 1914. Although the Bronx is the third-most-densely-populated county in the U.S., about a quarter of its area is open space, including Woodlawn Cemetery, Van Cortlandt Park, Pelham Bay Park, the New York Botanical Garden and the Bronx Zoo in the borough's north and center, on land deliberately reserved in the late 19th century as urban development progressed northwards and eastwards from Manhattan with the building of roads, bridges and railways.

The Bronx River was named for Jonas Bronck, an early settler from Småland in Sweden whose land bordered the river on the east. The borough of the Bronx was named for the river that was "Bronck's River". The indigenous Lenape (Delaware) American Indians were progressively displaced after 1643 by settlers from the Netherlands and Great Britain. The Bronx received many Irish, German, Jewish and Italian immigrants as its once-rural population exploded between the mid-19th and mid-20th centuries. They were succeeded after 1945 by African Americans and Hispanic Americans from the Caribbean basin — especially Puerto Rico and the Dominican Republic, but also from Jamaica. In recent years, this cultural mix has made the Bronx a wellspring of both Latin music and hip hop.

The Bronx contains one of the five poorest Congressional Districts in the U.S., (the 16th), but its wide variety of neighborhoods also includes the affluent Riverdale and Country Club. The Bronx, particularly the South Bronx, saw a sharp decline in population, livable housing, and the quality of life in the late 1960s and the 1970s, culminating in a wave of arson, but has shown some signs of revival in recent years.

The Bronx street grid is irregular. Like the northernmost part of upper Manhattan, the West Bronx's hilly terrain leaves a relatively free-style street grid. Much of the West Bronx's street numbering carries over from upper Manhattan, but does not match it exactly; East 132nd Street is the lowest numbered street in the Bronx. This dates from the mid-19th century when the southwestern area of Westchester County west of the Bronx River, was incorporated into New York City and known as the Northside.

The East Bronx is considerably flatter, and the street layout tends to be more regular. Only the Wakefield neighborhood picks up the street numbering, albeit at a disalignment due to Tremont Avenue's layout. At the same diagonal latitude, West 262nd Street in Riverdale matches East 237th Street in Wakefield.

Three major north-south thoroughfares run between Manhattan and the Bronx: Third Avenue, Park Avenue, and Broadway. Other major north-south roads include the Grand Concourse, Jerome Avenue, Sedgwick Avenue, Webster Avenue, and White Plains Road. Major east-west thoroughfares include Mosholu Parkway, Gun Hill Road, Fordham Road, Pelham Parkway, and Tremont Avenue.

Most east-west streets are prefixed with either East or West, to indicate on which side of Jerome Avenue they lie (continuing the similar system in Manhattan, which uses Fifth Avenue as the dividing line).

The historic Boston Post Road, part of the long pre-revolutionary road connecting Boston with other northeastern cities, runs east-west in some places, and sometimes northeast-southwest.

Mosholu and Pelham Parkways, with Bronx Park between them, Van Cortlandt Park to the west and Pelham Bay Park to the east, are also linked by bridle paths.

Approximately 61.6% of all Bronx households do not have access to a car. Citywide, the percentage of autoless households is 55%.
