Recent legislation changed the way state prisoners are counted in the Census. Previously, they were counted in the communities where their prisons were located, but now they are being counted where they lived before being sent to prison.
So a prisoner from Brooklyn held in Great Meadow in 2010 is now being counted among the population of Brooklyn, not Washington County.
The change makes sense. Most prisoners do not move, in any real sense, to the communities that host prisons. Most inmates stay in state prisons only two or three years, and when they’re released, they rarely settle down where they were incarcerated. They go home.
