Ashley Halsey III and Jon Cohen describe in their article for The Washington Post how Zipcars are popular with young white college graduates.
"The typical D.C. Zipcar user is a white college graduate younger than 39 who lives in Northwest, the survey found. The vehicles are less popular among black college graduates, with 8 percent saying they use them. With people older than 40 - also just 8 percent. People who haven't graduated from college typically are not inclined to drive Zipcars.
"'Generation Y doesn't feel the need to own a car,' said Chris Hamilton of the District, who works as Arlington County's Commuter Services bureau chief. 'They want to live in places they can get around without one. The car isn't the same status it once was.'"
