Aims to investigate the gambling behavior and attitudes of adults and youth in America and estimate the effects of gambling facilities on a variety of local economic and social indicators. Questions 2,417 adults and 534 young people aged 16-17, and 530 regular gamblers through a telephone survey. Covers topics such as gambling-related attitutes and behaviours, substance use, mental health and demographics. A longitudinal community database includes geographic information for 100 communities on gambling availability and spending, bankruptcy, and government expenditure between 1980 to 1997. 10 case studies looked at the effects of large casinos in close proximity. Finds that about 2.5 million adults are pathological gamblers, and another 3 million adults problem gamblers. The availability of a casino within 50 miles is associated with about double the prevalence of problem and pathological gamblers. Pathological, problem, and at-risk gambling are proportionately higher among African Americans than other ethnic groups, although African Americans still comprise a minority of all pathological gamblers.
