Why do they say Brooklyn is the 7th largest City? -

Well it s actually known as The Fourth Largest City in the US.Because before the amalgamation of New York City in 1898, Brooklyn was its own city and a very large one. Brooklyn is the most populated borough in New York City, with over 2.5 million people. Most people think Manhattan is the most populated borough, but it s actually third behind Brooklyn and Queens.Brooklyn is larger than Houston which is the 4th largest city in the US. So that s why it s known that way.
