Racial dot density map

There are many ways of showing demographic data on a map. A racial dot density map uses different colors of dots to represent the relative numbers of people of different races within an area.

This map style was inspired by the Racial Dot Map created by Dustin Cable at the University of Virginia.

The following video shows how to download US Census data from censusreporter.org and use QGIS to create a racial dot map, where each dot represents one or more people, color-coded by race. To do this, we create a QGIS polygon style that uses multiple "random marker fill" symbol layers.
