A new interactive map hosted by the University of Cincinnati shows the racial diversity of every neighborhood in the continental United States. It can also show how racial diversity has changed in each of those neighborhoods over the last twenty years.
The Racial Diversity map uses census data to visualize the dominant racial group in each 30 meter by 30 meter square in the country for the years 1990, 2000 and 2010. It is therefore possible to show how racial diversity has changed (or not) in towns and cities across the country over the last twenty years. The map also allows you to view population density at the same level across the continental United States.
If you want to use the data to show the racial diversity or population density on your own maps you can download the data in GeoTIFF format (each download is limited to an area no more than 100000 km2).
