OP,

Just a couple questions just to make sure I am understanding a few of these maps correct...

Are they saying that despite states with HIGH incarceration rates (Ex: LA, AR, MS) there are more whites being incarcerated in those states? If so that is interesting as the ratio is per 100,000 population of same race living there. So it takes into account disproportional number of sample sizes in the populations.

Also, any idea on the breakdown on the drug offenses that led the federal prison sentences? Are they distribution? Possession? Both? Are they marijuana? Are they more "hardcore" drugs, i.e. cocaine, heroin, fentanyl, ectacy, speed, etc...?

Thanks in advance.
