Nearly one-third of the estimated 6.4 million people in U.S. who commute to work using public transportation live in New York City according to new Census Bureau data. Data, based on a new analysis of the American Community Survey released Tuesday, revealed that New York is the only city where the majority of workers--55%, or 1.9 million people-- commute from home to work via public transportation. Other cities with high transportation rates included Washington, D.C. (37%), Boston and San Francisco (31% each), Chicago and Philadelphia (27% each), Newark, N.J. (26%) and Baltimore (25%). Only one-in-eight workers (12%) in Los Angeles, the nation's second largest city, use public transportation. Overall, only 5% of the nation's 128.6 million workers use public transportation to get to work. Bus transportation accounted for 55% of public transportation use nationally; subway or elevated rail use ranked second at 29%.
