Rats in New York City are widespread, as they are in many densely populated areas. They are considered a cultural symbol of the city. For a long time, the number of rats in New York City was unknown, and a common urban legend declared there were up to five times as many rats as people. However, a 2014 study estimates that there are approximately 2 million rats in New York, which is close to a quarter of New York's human population.
