Links between casino proximity, increased casino participation, and gambling-related problems are reported in the gambling and casino proximity literature but the relationship between casino proximity and urban casino communities have not been fully investigated in current literature. The three A’s (accessibility, availability, and acceptability), known as ecological predictors of casino-gambling participation, have also been linked to the flood of casinos, including the influx of urban casinos in major metropolitan cities along the northeast corridor. Gambling legalization, regulation, and casino proliferation in the United States have increased casino-gambling participation.
