That is almost 5000 dead people who voted in the Detroit area. This is old-fashioned voter fraud and surely enough to turn many local elections.
Detroit area covers a lot of territory.
Within Detroit, there are a few concentrations, or clusters, found in the data -— that would indicate a medical/retirement “community” that might be worth a closer look by inspectors.
There are also a few instances of concentration, around Lansing, Flint, and Saginaw -— when you see the full data set sorted on the ZIP CODE.
That, I cannot display online, because of display limitations: 835 ZIP CODE lines would not go over well, at FreeRepublic -— I had to cut the CITIES display (reply 48) from 649 to 281 lines.
