Urban Institute creates intriguing on-line "Prison Population Forecaster"

I just learned about this notable new on-line resource from the Urban Institute, which it calls "The Prison Population Forecaster." Here is how the tool is described at the site:

Roughly 2.2 million people are locked up in prison or jail; 7 million are under correctional control, which includes parole and probation; and more than $80 billion is spent on corrections every year.

Research has shown that policy changes over the past four decades have put more people in prison and kept them there longer, leading to exponential growth in the prison population even while crime has dropped to historic lows.

But despite widespread agreement that mass incarceration is a serious problem, the national conversation is light on details about what it will take to achieve meaningful and sustainable reductions. What do states actually need to do roll back their prison populations by 10 percent? 20 percent? 50 percent?

To advance the policy conversation, decisionmakers and the public need to know the impact of potential policy changes. Our Prison Population Forecaster can estimate the effect, by state, of policies that aim to reduce prison admissions and length of stay for the most common types of offenses.

The tool currently uses data from 15 states, representing nearly 40 percent of the national prison population, to forecast population trends and project the impact of changes on rates of admission or lengths of stay in prison.

Using the tool, we can see that in some states, limiting prison admissions to only new crimes and diverting parole and probation revocations will substantially reduce the number of people behind bars. Other states can stem prison growth by tackling how they address drug and property offenses. Still others may discover that modest reductions in time served for violent offenses are necessary.

This forecasting tool paves the way for a more productive conversation about the need for tailored reforms that address the unique drivers of mass incarceration in each jurisdiction.
