A geospatial analysis between the sale prices of single-family properties and the presence of registered sex offenders in Jefferson County, Kentucky

This study explores whether a relationship exists between sale prices and the presence of registered sex offenders in Jefferson County, Kentucky after accounting for observed and unobserved neighbourhood characteristics in accompaniment with property characteristics. The sale prices of single-family properties sold in 2015 were estimated as a function of the characteristics of the property, the housing and population characteristics of the neighbourhood, block group fixed effects and two separate measures of sex offender presence: a) the distance of the nearest registered sex offender to sold single-family properties; and b) the density of registered sex offenders within a half mile distance to sold single-family properties. Registered sex offender distance and density are associated with sale price when controlling for property characteristics and observed neighbourhood characteristics of the property, but these relationships cease to exist when unobserved neighbourhood characteristics are accounted for in the model.
