There are 8,491,079 people living in New York City as of 2014. Sounds like a lot for a single city right? Shockingly enough though, ancient Rome was around 8 times more densely populated than modern NYC! These millions speak more than 800 languages total, making the city of New York the most linguistically diverse one in the world. NYC is known as a melting pot of nationalities, heritages and cultures.
