Those stats are based on a tiny fraction of the US prison population. From elsewhere on that site, that agency is responsible for "158,012 Inmates".

Only statistic which I could find on short notice (literally first google result ...) but considering it's federal, I trust a small sample size more than random numbers from someone on the internet without quotation, especially if they are off by an order of magnitude from other countries.

The clue is: It looks like the numbers are reversed which would make a lot more sense.

according to [0], out of 1.04M in state prisons it's:

  - 606k violent
  - 142k drug
  - 159k property
  - 124k public order (which includes 42k weapons and 18k DUI)

selection bias: federal crimes are a specific subset, so federal inmates are not a representative sample
