The demographics of Brooklyn reveal a very diverse borough of New York City and a melting pot for many cultures, like the city itself. Since 2010, the population of Brooklyn was estimated by the Census Bureau to have increased 3.5% to 2,592,149 as of 2013, representing 30.8% of New York City's population, 33.5% of Long Island's population, and 13.2% of New York State's population. If the boroughs of New York City were separate cities, Brooklyn would be the third largest city in the United States after Los Angeles and Chicago.
