This study examines the density of lottery outlets within ethnically concentrated neighborhoods in Middlesex County, New Jersey, using geospatial statistical analyses. No prior studies have empirically examined the relationship between lottery outlet density and population demographics. Results indicate that lottery outlets were not randomly dispersed across the county but rather were significantly clustered in some census tracts. Using geospatial statistical analysis, percent poverty was found to be negatively related to the density of lottery outlets, while percent commercial use was highly positively related. Percent Hispanic was strongly significant in all the models predicting lottery outlet density and had the highest explanatory power other than percent commercial. Other independent variables, including median household income and race (African American and White) were not found to be significant predictors of lottery outlet density. Implications for policy and research are discussed. (Contains 3 tables and 3 figures.)
