The Most Dense City You've Never Heard Of

"Maywood, about 10 miles southeast of downtown Los Angeles, is one of the downriver working-class cities that rarely penetrate the consciousness of upriver people. It's small, only 1.2 square miles, but inhabited by an estimated 40,000 souls (30,000, if you believe a recent state study, which no one in Maywood does). At either number, it's the most densely populated city in California."
