This study examines whether county sex offender residence restrictions were associated with reduced sex crime arrest rates in New York State. In doing so, this study draws on the limited prior research regarding the effectiveness of residence restrictions, and on the extensive literature regarding the incapacitation and deterrence of crime through public policy measures. Results indicate that residence restrictions were not associated with significantly reduce arrests for sex crimes committed either by RSOs or non-RSOs against child victims. However, results suggested that these policies may generally deter some non-RSOs from sexually victimizing adults. Implications for future research and policymaking are discussed.
