Eric Fischer was inspired by Bill Rankin’s Chicago map of racial and ethnic divides which took the recent Census data and dotted a city map with colored dots equaling groups of the same race…so he did the same thing for other cities. Not sure if this really counts as being “inspired”. “Thought that it was cool so I did the exact same thing.” might be closer.
Below is Fischer’s map of St. Louis. Each dot is 25 people. Red is white, blue is black, green is asian, orange is hispanic and gray is “other”/white guys that wear their hat sideways.
