Last month I posted a color-coded map of the Los Angeles area based on race and ethnicity, the work of artist Eric Fischer, who has created a series of similar maps of U.S. cities based on 2000 Census data.
This map of Orange County, also by Fischer, illustrates the ethnic makeup of the county thus, per an explanation by Fischer on his Flickr page:
I was astounded by Bill Rankin’s map of Chicago’s racial and ethnic divides and wanted to see what other cities looked like mapped the same way. To match his map, Red is White, Blue is Black, Green is Asian, Orange is Hispanic, Gray is Other, and each dot is 25 people.
Specific cities within Orange County can be identified by dragging the cursor over the map.
The map is especially interesting in light of how the county's demographic changes have become a factor in the race for the 47th Congressional District, which encompasses the cities of cities of Garden Grove and Santa Ana and takes in parts of Fullerton and Anaheim. The changing face of Orange County had a role in the 1996 defeat of incumbent Bob Dornan, a Republican, by Loretta Sanchez, a Latina and a Democrat. Now Van Tran, a Vietnamese-American and a Republican, is vying for Sanchez's seat.
