"Forecasting US Crime Rates and the Impact of Reductions in Imprisonment: 1960-2025"

The title of this post is the title of this notable new report authored by James Austin and Richard Rosenfeld for the Harry Frank Guggenheim Foundation.  Here is how the 25-page report is introduced on the HFG Foundation website:

In the latest of a series of HFG reports forecasting crime trends at the US national level and for selective states and (forthcoming) cities, James Austin and Richard Rosenfeld again created statistical models that retroactively “predicted” property and violent crime rates for past years with great accuracy and then used these models to forecast crime trends in the near future.  This report concerns national trends, updating the authors’ national-level HFG report released in 2020, before the social and economic disruptions of the pandemic and civil unrest over police violence interrupted a 25-year declining or flat trend in violent crime.

Austin and Rosenfeld forecast very modest increases in violent crime and then a flattening trend by 2025 as well as a continuation of the longstanding decline in property crime. They also use their forecasting models to project the effect of augmenting the nation’s declining rate of imprisonment by an additional 20%. Such a policy decision, they conclude, would not lead to significantly higher crime rates.
