86% of all police stops in Ferguson, Missouri (2013) were of Black people

5. But you raise an important point.

Because it's not just race, it's age.

All things being equal, younger people--those in their late teens and early-mid 20s tend to get arrested more often than older people.

I'm not going to crunch numbers. But in general, the younger population is less white and more black than the older population. It's highly unlikely to come up to the 80+% that the police stats hit for arrests, but the percentage of the population with slightly higher arrest rates simply due to age pushes that number back up from 63% to higher. Perhaps 70%. Perhaps 68%. Perhaps 75%.

Given life expectancy of male versus female, I'd also suspect that more of the older white population is female, just in case somebody looks at the arrest stats by sex instead of race.

We won't even go into descriptions of suspects cross-tabbed for race of suspect and race of witness.
