The word "Bronx" originated with Swedish-born (or Faroese-born) Jonas Bronck, who established the first European settlement in the area as part of the New Netherland colony in 1639. These open spaces are primarily on land reserved in the late 19th century as urban development progressed north and east from Manhattan. The Thain Family Forest at the New York Botanical Garden is thousands of years old it is New York City's largest remaining tract of the original forest that once covered the city. About a quarter of the Bronx's 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. Bronx County was separated from New York County in 1914. The West Bronx was annexed to New York City in 1874, and the areas east of the Bronx River in 1895. East and west street names are divided by Jerome Avenue. The Bronx is divided by the Bronx River into a hillier section in the west, and a flatter eastern section. With a population that is 54.8% Hispanic as of 2020, it is the only majority-Hispanic county in the Northeastern United States and the fourth-most-populous nationwide. It is the only borough of New York City not primarily on an island. Of the five boroughs, it has the fourth-largest area, fourth-highest population, and third-highest population density.

If each borough were ranked as a city, the Bronx would rank as the ninth-most-populous in the U.S. The Bronx has a land area of 42 square miles (109 km 2) and a population of 1,472,654 in the 2020 census. It is south of Westchester County north and east of the New York City borough of Manhattan, across the Harlem River and north of the New York City borough of Queens, across the East River. The Bronx ( / b r ɒ ŋ k s/) is a borough of New York City, coextensive with Bronx County, in the U.S.
