Reducing Housing Options for Convicted Sex Offenders: Investigating the Impact of Residency Restriction Laws Using GIS

2006:

Abstract
Sex offender registries have been established throughout the United States. To date, 16 states have adopted additional residency restriction policies, precluding registered sex offenders from living within a certain distance of places where children gather. This study quantifies the impact of residency restrictions on housing options for registered sex offenders using Orange County, Florida, as a case study. A Geographic Information System (GIS) is employed to identify all occupied residential properties using parcel-level zoning data as well as those that fall within the 1,000-foot restricted buffer zones around attractions, bus stops, daycares, parks, and schools. Results indicate that housing options for registered sex offenders within urban residential areas are limited to only 5% of potentially available parcels and that bus stop restrictions impact the amount of livable area the most, followed by daycares, schools, parks, and attractions. The limited options to establish residency exist mostly in low-density rural areas. This supports the argument that residency restrictions for sexual offenders are a strong contributing factor to their social and economic isolation. The impacts of increasing the buffer to a proposed 2,500-foot zone are discussed, and a comparison of the individual restriction categories is presented. ..more.. by Paul A.
