This image shows the concentration of the largest ethnic groups visualized per address on a satellite image.Ethnicity Map of American Voters per Address
For these nine maps we mapped all 164 million registered voters in the US to their actual address and assigned a color depending on the percentage of voters on the address that had a certain ethnicity. The map also shows the density of the US population as we increased the transparency of the colors if the population density was lower. The coloring is brighter the higher the density and as a result population density patterns emerge.
The image below shows the same data but here the ethnicity is colored per county and projected over a map background instead of a satellite image.
