The Washington Post does the math:

A third of people who have lived in the District for less than a decade described themselves as Zipcar users, a Washington Post survey found, and they’re also most likely to cruise around town on the red bicycles offered by the Capital Bikeshare program.

At least, that goes for young white college graduates. Black college graduates are far less likely to use Zipcar (and presumably, Capital Bikeshare). According to the Post, about 25 percent of District households don’t own cars.

Meanwhile, the rest of the city—-people over the age of 30, people who aren’t college graduates, and people who often aren’t white—-continues to use cars (albeit less, probably because the gas is too damn high).
