The Bronx

The Bronx is New York City's northernmost borough. It is the only one of the city's five boroughs situated on the United States mainland rather than on an island. As of 2005, the United States Census Bureau estimated that the borough's population was 1,357,589.[1] Its population has increased since a decline that began after the 1960 census. The borough had its peak population in 1950. [2] The Bronx is the fourth most populous of New York City's five boroughs, and Bronx County is the fifth most populous county in the New York Metropolitan Area. Although commonly known as "The Bronx",[2] the official county name does not include the definite article ("The").

The name refers to the Bronx River, and rivers are commonly referred to with the article (e.g. "the Hudson").[3] The river was named for Jonas Bronck, a Swedish sea captain and 1641 resident whose 500-acre (2 km²) farm between the Harlem River and the Aquahung[4] comprises part of the modern borough.
