Seattle has the most cars per capita
Seattle's construction boom is well known, but perhaps surprising to some is that cars are being added at the same rate as people.
Both the population and the number of new cars owned by city residents grew by 12 percent from 2010 to 2015, according to Census Bureau data. That surge in newcomers earned Seattle a spot on the list of the 10 most densely populated big cities in the U.S.
Gene Balk, "FYI Guy" at The Seattle Times, reported for every 1,000 residents there are 637 cars, "easily the most cars per capita."
"Our car 'population' hit 435,000, all crammed into the city's 84 square miles of land area," Balk stated, acing, "That pencils out, in case you're wondering, to 5,185 cars per square mile. If you ranked major U.S. cities by density of cars instead of people, Seattle would place fifth."
By comparison, San Francisco has 160,000 more people than Seattle, but about 50,000 fewer vehicles.
