The county is only 40% black. https://www.census.gov/quickfacts/fact/table/waynecountymich... And the kits were put in storage from 1984-2009, during which time the demographics of Detroit changed very rapidly. https://en.wikipedia.org/wiki/Demographic_history_of_Detroit... It wasn't always 80% black.

The kits are from a Detroit Police warehouse. The rest of Wayne county has different police forces.

The oldest kit was from 1984, not all the kits.

Your Wikipedia chart shows Detroit has been at least 80% non-white since 1990.

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.

Very good points. Thank you.

They're actually terrible points, which are very shallow and not pertinent to the situation
