CityLab: The Great Divide in How Americans Commute to Work

Drive alone to work: More than three-quarters (76.4 percent) of commuters drive to work alone. But in the New York metro area, the share is just about half. It’s 57 percent in San Francisco; about two-thirds in Boston, Washington, D.C., and Seattle; and about 70 percent in Chicago and Portland. And, as might be expected, a smaller-than-average share of workers drives to work alone in more compact college towns such as Boulder, Colorado; Corvallis and Eugene, Oregon; Ann Arbor, Michigan; and Ames and Iowa City, Iowa.[...]

Bike to work: Just half of a percent of Americans nationwide bike to work. But nearly 7 percent do in Corvallis, Oregon, and more than 4 percent in Boulder; Ames; and Santa Cruz, California. Two or three percent of commuters get to work by bike in other college towns: Gainesville, Florida; State College; Ann Arbor; and Madison, Wisconsin. Among large metros (with more than 1 million people), almost 2 percent of commuters get to work by bike in San Jose and San Francisco. [...]

Education is another piece in the picture of how Americans get to work. People are less likely to drive to work alone and to use alternate modes in metros where more adults are college graduates. The share of adults with college degrees is negatively and significantly (-0.41) associated with driving to work alone, and positively and significantly associated with using transit (0.56), biking (0.62), walking (0.56), and working from home (0.50), although it is not statistically associated with carpooling. [...]

The way we get to work is also related to our political cleavages. On the one hand, commuters in more progressive metros—those where Hillary Clinton got a bigger share of votes in the 2016 election—are more likely to walk (0.44), bike (0.44), or use transit (0.59), and less likely to drive to work alone (-0.36). Commuters in more conservative metros, where a larger share voted for Trump, are more likely to drive to work alone (0.44). This reflects the fact, though, that more liberal metros tend also to be denser, more affluent, and more educated.
