Demographics, Diversity, and the 2010 Census
by Ben Lorica (last updated Aug/2011)
Using data from the 2010 Census, I've created a series of diversity heat maps. I took a few of the major ethnic groups used by the U.S. Census Bureau and grouped the over 3,000 counties in the U.S. (The raw data I started with was the percent share of ethnic groups within individual counties.) In the maps below, a darker shade signifies a higher/larger value. So in the case of the ethnic groups, a darker shade of red means the share of the selected group is higher in a county. Similarly for population density, a darker shade of red means a higher population density.There is one exception to the coloring scheme:
Rate-of-change (population growth from Census 2000 to Census 2010): Light Red (rapid decrease) to Black (roughly no change) to Light Green (rapid increase).This is a work in progress, and I'll refine the interface over the next few weeks.
A few observations:
[Data is from the fabulous USA Today Developers Network.]African Americans have their highest share of county populations' in the South.
Hispanics have their highest share of county populations' in the Southwest.
Asians have the highest share in the SF Bay Area and Hawaii, a fact I noted in a blog post.
