Brooklyn is the most populous of New York City's five boroughs, with nearly 2.6 million residents, and the second-largest in area. Since 1896, Brooklyn has had the same boundaries as Kings County, which is now the most populous county in New York State and the second-most densely populated county in the United States, after New York County (Manhattan). It is also the westernmost county on Long Island.

Brooklyn was an independent city until its consolidation with New York City in 1898, and continues to maintain a distinct culture, independent art scene, and unique architectural heritage. Many Brooklyn neighborhoods are ethnic enclaves where particular ethnic groups and cultures predominate.
