Sources and methodology

Prisoners (state and federal)
This is the number of state and federal prisoners incarcerated in the district. The Census publishes the number of incarcerated people in each block in Summary File 1, Table P37. We then identified which incarcerated populations in each block were state or federal prisoners.
Black prison population
The Census publishes the race of the correctional population at the tract level in Summary File 1, Table PCT17B and at the block level for the total population in Table P7. We used these two data sources to identify the number of Black prisoners incarcerated in state or federal prisons in blocks in each district.

Black population
