The Gender Divide: Tracking women's state prison growth

Gender Divide report thumbnail Even as men’s incarceration rates are falling, women’s incarceration rates remain near record highs, a trend driven by criminal justice decisions at the state level. Our new report breaks down women’s incarceration trends in state prisons for all 50 states since 1978. We find that women have scarcely benefited from efforts to reduce state prison populations since 2009. In many states, treating women’s incarceration as an afterthought has, in effect, held back efforts to decarcerate.
