The population density of Manhattan is much lower today than it was 100 years ago, and total population has fallen by about 25%. Manhattan had a census-estimated 2014 population of 1.6 million, but on business days, the influx of commuters increases that number to over 3.9 million or more than 170,000 people per square mile.
According to the Mayor's Office of Media and Entertainment, countless popular films have used hundreds of locations across Manhattan as a backdrop in the past 50 years. (Literally, countless. The office, which approves filming location permits in NYC, was unable to provide a solid number). Those films include:
"Taxi Driver" (pictured), filmed at Bellmore Cafeteria on Park Avenue and along Columbus Avenue.
"13 Going on 30," filmed in Times Square.
"Spider-Man," filmed in midtown Manhattan.
