Prison population and the census

[Angrie]

There are categories for "Institutionalized Population" which you can search on using American Factfinder and tools like that.

This is not exactly the same thing as the prison population, but it is close, and there are variations on it.

Similarly, there is "Civilian Noninstitutionalized Population."
