Environmental issues in New York City
New York is distinguished from other American cities by its extensive use of public transportation. While nearly 90% of Americans drive to their jobs, public transit is overwhelmingly dominant for New Yorkers. According to the 2000 U.S. Census, New York City is the only locality in the United States where more than half of all households do not own a car (the figure is even higher in Manhattan, over 75%; nationally, the rate is 8%). About one-third of users of mass transit in the United States and two-thirds of the nation's rail riders live in New York and its suburbs, and New York City's public transit system accounts for nearly four times as many passenger miles as the Washington, D.C., and Los Angeles metro regions combined. Only 6% of shopping trips by New Yorkers involve the use of a car.
