Manhattan
Of Manhattan's 1.63 million residents, 49.1 percent (2013) of them speak a language other than English in the home. According to a report released by the United States Census Bureau, more than 192 languages are spoken in the New York metropolitan area, however some experts believe upwards of 800 languages are spoken on the island on any given day, making Manhattan the most diverse 23 square miles in the world.
Brooklyn
Brooklyn is New York's most populated borough and the second largest in size. In fact, if Brooklyn were not a borough, it would be the fourth largest city in the country. In Brooklyn, the most common language spoken after English is French, due in large part to the borough's thriving Caribbean community centered in Flatbush — the largest West Indian community outside of the Caribbean after Toronto, Montreal, London and Miami. Brooklyn also boasts more than a dozen other ethnic neighborhoods, from Arabic to Spanish, Ukrainian to Greek.
Queens
Queens is home to one of the most diverse zip codes in the country, in Queens Village, not to mention the thriving multinational community that is Astoria. Basically any language you can imagine, and some you may never have heard of, are spoken in Queens — making it something of an “urban United Nations.”
The Bronx
In recent years, the rise of African languages spoken in the Bronx has been substantial, with more than 16 different African languages being spoken in the borough — a number experts believe to be low compared to the daily reality of life in the Bronx. In addition to this growing African-speaking community, others, such as Italian, Spanish, and Albanian speakers, continue a heritage that finds its roots in the Bronx for generations.
