A Study of 72 State Prison Growth Curves

Abstract

Growth curves for 36 state female and male prisons were compared to each other and the standard growth curve. The frequently used standard growth curve is the combined state and federal growth curves for both genders. Very few state curves were similar to the standard curve. Most states were able to stop the growth and some were able to establish and maintain negative growth at moderate rates. However, the prison populations of other states are continuing to increase.
