THE RELATIONSHIP BETWEEN CRIME AND INCARCERATION AMONG THE AMERICAN STATES1

Data from the 50 states for 1975 are analyzed to try to separate the presumed reciprocal effects on each other of crime rates and incarceration rates. Two-stage least-squares regression shows no significant effect of crime on incarceration nor of incarceration on crime. Incarceration rates are affected mainly by the percentage of blacks in the state population. Crime rates are significantly influenced by urbanization, region, mean income, and unemployment.
