Chronologically reviews the modern peer-reviewed literature on the relationship between casinos and crime in the USA, excluding organized crime. Introduces theoretical and methodological issues that have played a role in the research on casinos and crime. Finds that pre-2000 studies are generally methodologically or empirically weak. Their findings are heavily dependent on the analytical framework used, and suggest that casinos cause crime if visitors are not included in the population component of the crime rate. More recent studies have drastically improved in quality. Finds that when tourism is accounted for the in the model, the crime effect of casinos is diminished or disappears. Discusses some of the unresolved issues in research, particularly separating the effect of tourism and the effect of casinos on crime.
