Why Practice So Many Ex-Cons End Up Back in Prison?

Perchance they don't—a provocative new study says recidivism rates are drastically lower than we think.

One of the most frequently cited and dispiriting statistics well-nigh the American criminal justice system is that more than half of land prisoners end upwardly returning to prison within five years of their release.* These numbers come from a study conducted by the federal regime'southward Agency of Justice Statistics, in which researchers tracked about 400,000 people from around the country who were released from land prisons in 2005. The potent implication of the findings is that people who are incarcerated are extremely probable to reoffend in one case they're free and that most of them spend their lives in and out of correctional facilities.

Just what if the BJS's findings have been fundamentally misunderstood? That's the provocative contention of a recent paper published in the journal Crime & Delinquency, the championship of which is "Following Incarceration, Most Released Offenders Never Return to Prison house."

The newspaper, which was produced by researchers at the Cambridge, Massachusetts–based public policy house Abt Assembly and circulated online this week past criminal justice experts, argues that the conventional wisdom most recidivism in America is flatly wrong. In reality, the authors of the paper report, 2 out of 3 people who serve time in prison never come back, and simply 11 per centum come back multiple times.

The reason for the shocking discrepancy between these new findings and those of the BJS, according to Abt's William Rhodes, is that the BJS used a sample population in which echo offenders were vastly overrepresented.

I chosen Rhodes to enquire him about why this happened and how he and his co-authors avoided the aforementioned trouble in their assay. His explanation for why the recidivism problem is not nearly as bad equally many of us have believed is below; our chat has been lightly edited and condensed.

Allow'south start with the conventional wisdom on recidivism in the U.S. What is it, and where did it come from?

The conventional wisdom is that there's a very high rate of recidivism, where recidivism is defined as being arrested for a new criminal offense or having your customs supervision status revoked for a technical violation.

I know the Bureau of Justice Statistics has collected statistics on backsliding at least twice, perhaps three times, and what they do is start with a sample of offenders who are released from prison during a given twelvemonth, then match those release records with criminal history records to make up one's mind who recidivates. Then they compute their statistics—the rate at which the released offenders are arrested for new crimes and the charge per unit at which they're readmitted to prison—by observing the individuals in their sample over a menstruum of some years. They're non controversial statistics. There's no manipulation that goes on. It's purely tabulation.

So the fashion it works is they choose a yr and track a accomplice of people in their sample and run across who comes dorsum? It seems pretty straightforward.

That's exactly right.

And so what's incorrect with their results?

It is difficult to explain to a nonstatistician. I endeavor to use an illustration: Suppose that I were asked to describe a population of people who become to shopping malls. What I might do is become to the mall and perform an "intercept survey"—that is, I'd randomly select people who are entering the mall and ask them about themselves—tape their historic period, sexual activity, race, and frequency of visiting the mall. The problem is, I'd probably do that over a pretty short menstruum of time, like a week. And then I'd get a lot of people who are frequent mall visitors and fewer people who aren't. Yous know, if y'all go to a mall y'all'll run into an elderly population who go daily, to exercise by walking through the mall. You'll also come across a number of people who but like malls, and perchance they go weekly. Or you'll find, occasionally, people like me, who go virtually once a yr when they need to purchase a washing machine or something. If you did a simple tabulation of all the people you lot intercepted during a week you'd get a large proportion of frequent mall visitors. And they wouldn't be representative of people who visit malls—they'd exist representative of frequent mall visitors.

And the same matter is happening with the Bureau of Justice Statistics when they take a sample of people who have been released from prison during a given year.

Right. They're not attempting to be misleading. What they're reporting is truthful: If yous accept people who are released from prison during a given year, here'south the rate at which they'll return. Just information technology gets translated in people's heads as, "Here's what happens to offenders in full general."

In truth what yous take is two groups of offenders: those who repeatedly do crimes and accumulate in prisons because they get recaptured, reconvicted, and resentenced; and those who are much lower hazard, and most of them will go to prison in one case and not come dorsum.

So the problem with taking a snapshot of a item yr, the way the BJS has done it, is you're more than likely to have people in your sample who come back a lot than yous are to have people who don't come back at all.

That'due south exactly right, yes.

What data is your study based on?

At Abt Assembly we get together data into something called the National Corrections Reporting Plan. Information technology records prison terms for offenders beyond almost all of the states. For a large number of states, that data goes back to 2000. So nosotros tin notice when somebody enters and when somebody exits prison, and that allows u.s.a. to wait at individual offenders and say, "Given that they've been incarcerated at least once, how frequently practise they come back?" And then you're looking at a large number of offenders, over a near 15-year menstruation, and what you find is that most of those offenders do not come back. They're incarcerated, they serve their term, they don't return.

So your data set contains information at the individual level? You lot know when a specific person went in and when he got out?

That's correct. If y'all were in the dataset, nosotros would runway you. Nosotros probably wouldn't have your name, simply we'd take an identification code that the land would issue you as an inmate.

And then what do you have to practice to correct for the overrepresentation of echo offenders in the dataset?

You weight them differently. It's not capricious of course—the weighting is done so that you have an appropriate representation of all offenders rather than an overrepresentation of high-rate offenders. In order to get the right weights, yous have to be able to observe a long menstruation—the xv years we look at.

So the reason you lot're looking at the stretch of time, rather than merely one year, is it gives yous what y'all demand to know in lodge to weight specific individuals the correct amount.

That'due south correct.

Correction, November. 2, 2015: This commodity originally misstated that a Bureau of Justice Statistics study on recidivism found that 68 percent of state prisoners ended up dorsum behind bars within three years of their release, and about 75 pct came dorsum within five. These numbers referred to rates of re-arrest, not re-imprisonment. The BJS study found that almost l and 55 percent of state prisoners returned to prison within three and five years, respectively. (Return.)

What's important is being clear most what question you're trying to answer. If your question is, "Of all the people who go to prison, what's the rate at which they come up back?" then our calculations are better. But if you lot wanted to ask a question about a specific release cohort—virtually people who are released during a given yr—and how frequently they come back, then the other methodology is the appropriate one. Simply they're questions nearly two dissimilar populations of people. The get-go one is the population of offenders in full general.

So what are the BJS numbers good for?

Well, at that place are reasons for using data similar that. You might practise it if you lot wanted to evaluate whether a program y'all introduced in prison reduced backsliding. So yous'd desire to await at a detail cohort that was released during a particular year and judge whether the handling you introduced was effective or not.

Just if you want to look at how offenders actually collaborate with the criminal justice organisation, then the methods we propose are more appropriate.

My agreement of the lives of people who go to prison was very much colored by the notion that they tend to be incarcerated over and over—that they come out of prison and they have a very small take a chance of staying free. What you're saying is that's only really truthful for a certain subset of the population of people who are incarcerated.

Yep, that'southward correct. Most people really do non render to prison. They're not caught in what we telephone call the cycle of incarceration. They don't churn, to utilize 1 of the popular words. Only some do.

Are there policy implications from this that you've thought near?

Yeah, I think there are. Information technology would accept more careful study, only others accept pointed out that there are very low-level offenders who manage to readjust, and you ought to focus the rehabilitation resources you have on those individuals who are high-risk offenders. They're the ones who are going to benefit most from treatment—or, I should say, society'due south going to benefit nearly from treating them. The problem, of grade, is identifying them. That'south why criminologists have attempted to develop risk assessment tools, to identify the high-risk offenders and treat them, while almost letting the others recover by themselves.
