New York City's five boroughs are Manhattan, the Bronx, Queens, Brooklyn and Staten Island. Most of these boroughs are individually as large as an average American city, and each area has its own amenities and attractions.
Brooklyn is the borough with the highest population, with nearly 2.6 million people as of July 2013. Queens is second with nearly 2.3 million inhabitants. Manhattan contains more than 1.6 million people, while the Bronx has more than 1.4 million citizens. Even Staten Island has more than 472,000 residents.
Each borough is a county within the state of New York. Brooklyn also exists as Kings County, Manhattan is also called New York County, and Staten Island is known as Richmond County. Bronx County and Queens County retain their same names.
The Bronx gets its name from the first European colonist to settle in the area, a Swede named Jonas Bronck. This northernmost borough is the only of the five attached to mainland New York, as Brooklyn and Queens sit on the edge of Long Island while Manhattan is cut off from the mainland by the Hudson and Harlem Rivers.
Staten Island is the southernmost borough. The island is the only one of the five boroughs without a public hospital or a subway system, as of 2015. Staten Island is home to one of the two largest Liberian communities outside of Africa.
