But you wouldn't expect the rapes to be randomly distributed. Wayne County is a tale of two cities. There are rich white suburbs and the poor, black city.
You have to compare the untest kits to the demographics of record victims. It's likely women of color are much more often victims of rape. That is the trend nationwide.
The point is that this is a city with a large majority of blacks, and it just so happens to have terrible police. That isn't a contingent circumstance.
Everyone with money left well before 1990, the vast majority of white flight took place in the 60s, 70s, and 80s
Edit sp332, lol yes 2/3 of the white population remaining in 1990 left after that, the problem with your line of thinking is 86% of the white population had already fled by 1990. 2/3 of 14% is not much...
