Remember Eric Fischer's maps on racial segregation in America's cities? They were inspired by radical cartographer Bill Rankin's work. In another installment, Rankin charted the country's racial density by using Census data from 2006 and 2010. The results aren't so surprising; black folks are more densely populated in the South and Northeast, while Latinos are mostly on the West Coast. Nonetheless, it still makes for good eye candy.
Two maps are necessary to understand the diversity of the population: an absolute measure of where people actually live (population density), and a relative measure of the majority or minority status of a population in a certain area (population as percent of total). The Census only tends to publish the latter, which woefully obscures the large minority populations in urban centers.
