The Bronx

The Bronx /ˈbrɒŋks/ is the northernmost of the five boroughs (counties) of New York City in the state of New York, located south of Westchester County. Many bridges and tunnels link the Bronx to the island and borough of Manhattan to the west over and under the narrow Harlem River, as well as three longer bridges south over the East River to the borough of Queens. Of the five boroughs, the Bronx is the only one on the U.S. mainland and, with a land area of 42 square miles (109 km²) and a population of 1,438,159 in 2014, has the fourth largest land area, the fourth highest population, and the third-highest population density.

The Bronx is divided by the Bronx River into a hillier section in the west, closer to Manhattan, and a flatter eastern section, closer to Long Island. East and west street addresses are divided by Jerome Avenue—the continuation of Manhattan's Fifth Avenue. The West Bronx was annexed to New York City in 1874, and the areas east of the Bronx River in 1895. Bronx County was separated from New York County in 1914.
