Racial Dot Map Points Out Rancho Bernardo's Demographics

A demographic researcher at the University of Virginia has put together a map with more than 308 million color-coded dots—one for each person in the United States—that not only shows how many people of each race or ethnicity are in local communities but how they are spread thoughout.

The map, by Dustin Cable at the Weldon Cooper Center for Public Service at the university, is based on the 2010 census. It shows a largely-white Rancho Bernardo, with Asian residents living throughout and concentrated at times in the western part of the community. The map uses blue dots for white people; green for black or African American; yellow for Hispanic or Latino; red for Asian and brown for other races. The dots are grouped according to census block and not exact addresses, which could explain some gaps in the mapping.

In the most recent census, San Diego reported a total population of 1,307,402 people. That includes 376,020 residents of any race who identified their ethnicity as Hispanic or Latino. 

How that breaks down:

• White: 59 percent
• African American: 6.7 percent
• Asian: 15.9 percent
• American Indian and Alaska Native: <1 percent
• Native Hawaiian and Pacific Islander: <1 percent
• Other: 12.3 percent
• Identified by two or more: 5.1 percent
