'Prisonized' Neighborhoods Make Recidivism More Likely
sciencehabit writes: One of the most important questions relating to incarceration and rehabilitation is how to discourage recidivism. After a prison stint, about half of convicts wind up back in the slammer within three years. But sociologist David Kirk noticed a pattern: convicts who moved away from their old neighborhood when released from prison had a much smaller recidivism rate. Kirk found that the concentration of former prisoners in a neighborhood had a dramatic effect on the likelihood of committing another offense (abstract). "So if an ex-con’s average chance of returning to prison after just 1 year was 22%—as it was in 2006—an additional new parolee in the neighborhood boosted that chance to nearly 25%. The numbers climb for each new parolee added. In some of the most affected neighborhoods—where five of every thousand residents were recent parolees—nearly 35% were back behind bars within a year of getting out." The rates stayed consistent even when controlling for chronic poverty and other neighborhood characteristics.
The experience of Memphis, Tennessee, as reported in The Atlantic, with breaking up high-crime neighborhoods and redistributing their inhabitants to other places: the bad guys quickly find their feet and begin preying on a broader class of victims, while the decent-but-poor find their social networks shattered.
