Densest Population in the Country?

If you’ve ever cursed your steering wheel while stuck in Los Angeles rush-hour traffic, then you probably suspect a lot of people live here. 

L.A., Long Beach and Anaheim account for the densest population in the country, with some 7,000 people for every square mile in that zone, according to 2010 census data, as reported by KPBS.

The population in Arcadia has hit 56,364, according to the 2010 Census.

California has the most urban centers in the U.S., with 95 percent of its population living in them, KPBS reported.
