Examining the efficacy of sex offender residency restriction

A helpful reader pointed me to this new research article, titled "Does Residential Proximity Matter? A Geographic Analysis of Sex Offense Recidivism," appearing in the April 2008 issue of Criminal Justice and Behavior.  Here is the abstract:

In an effort to reduce sex offense recidivism, local and state governments have recently passed legislation prohibiting sex offenders from living within a certain distance (500 to 2,500 feet) of child congregation locations such as schools, parks, and daycare centers.  Examining the potential deterrent effects of a residency restrictions law in Minnesota, this study analyzed the offense patterns of every sex offender released from Minnesota correctional facilities between 1990 and 2002 who was reincarcerated for a new sex offense prior to 2006.  Given that not one of the 224 sex offenses would have likely been prevented by residency restrictions, the findings from this study provide little support for the notion that such restrictions would significantly reduce sexual recidivism.
