United States General Accounting Office: Impact of Gambling - Economic Effects More Measurable Than Social Effects (Note: 72 page .pdf download)
Multi-year study with data drawn from FBI national crime statistics, various official state and local crime statistics, the Internal Revenue Service, the Small Business Administration, the National Institute of Health, the Department of the Census, the Department of Health and Human Services, the Department of Education, and an assortment of peer-reviewed, published academic studies and articles, among other sources. The upshot of the report is that while nationwide there was no discernable statiscally significant correlation between crime rate and the presence of casinos in communities, communities with casinos to a statistically significant extent had lower unemployment, higher average earnings and standard of living (including healthcare), lower suicide and bankruptcy rates, and overal more robust economic, infrastructure (including both public education and public safety assetts and personnel), and population growth than had otherwise essentially similar communities distant from and/or without casinos.
