Mapping Census in ArcGIS



The most ethnically diverse regions are expressed by the darkest pink. The states containing counties with the highest diversity are California, Washington, New Mexico, Texas, Colorado, Florida, Kansas and Idaho. The majority of the diversity is on the West Coast. The East Coast has a low percentage of diversity.



The vast majority of the Black population is concentrated in the southern states. The ethnic group tends to live closely together in very specific regions and the percentages slowly dissipate as the distance away increases. The Midwest has a very low percentage of Blacks and the West Coast has a slightly higher percentage then the Midwest. California in particular has about 16-31% Blacks in some counties.



Asians are more widely dispersed then the Black populations. High concentrations exist in California, Washington and a few counties on the Eastern Coastline. Asians appear to be relatively intermixed with the other ethnic populations on a national level. The significantly higher coastal populations are likely due to immigration patterns.
