Manhattan's 16 miles long and two miles wide, so its walkability really isn't in question. Densely packed areas such as Brooklyn's Fort Green, Park Slope and Carroll Gardens and Bay Ridge, Queens' Sunnyside and Astoria/Long Island City and the South Bronx, University Heights and Fordham neighborhoods in the Bronx all give Manhattan a run for their money thanks to unyielding density and the sprawling Metropolitan Transit Authority. Last year, the MTA moved more than 3.2 billion riders with its buses and subways, with more than two-thirds of that total riding the rails. That doesn't even count the 81 million commuter rail riders taking the Metro-North, another 95 million on the Long Island Railroad, 4.3 million on the Staten Island Railway and millions more coming in from New Jersey on PATH and NJ Transit trains. Not only is 86% of New York eminently walkable, but only 2% of all New Yorkers live in neighborhoods that require owning a car. If you've ever tried to navigate past Lincoln or Holland tunnel traffic or a Cross Bronx Expressway tie-up on a weekday, you'd understand why.
