A new interactive map lets you zoom in to view the racial diversity and population density of every neighborhood in the United States.

The map, which displays more than 308 million points—one for each person residing in the United States—is the only one of its kind to apply racial and ethnic data from the 2010 US Census.

“I created the map mostly out of curiosity after seeing the original Census Dotmap developed by Brandon Martin-Anderson,” says Dustin Cable, senior research associate at the Weldon Cooper Center for Public Service’s Demographics and Workforce Group. “Starting with that idea, I added racial data from the Census Bureau. I then plotted the points, made the images, and hosted it through Google Maps.

“The entire code is open for people to see and use as they wish on GitHub.”

“Many have described it as demographic artwork,” says Qian Cai, director of the Demographics and Workforce Group. “What makes this map stand out is that each point is color-coded by race and ethnicity information contained in census data.

“While all that data could be overwhelming, this map elegantly, and beautifully, conveys thousands of pages of information in a simple, intuitive way. It is easy to see areas of high population density and racial concentrations across regions at one glance.”

The new map, available for use by anyone with an interest, could be a resource for teachers and students, and may be useful in planning for transportation, housing construction, schools, and other functions of government.

Researchers also expect private-sector employers may use the information to understand more about their customers and markets.
