This study obtained information on youth-serving organizations around the country that provide constructive activities for youth in the after-school and evening hours. It was carried out in collaboration with seven national youth-serving organizations: Boys and Girls Clubs of America, Boy Scouts of America, Girls Incorporated, Girl Scouts of the U.S.A., National Association of Police Athletic Leagues, National 4-H Council and United States Department of Agriculture 4-H and Youth Development Service, and YMCA of the U.S.A. The research involved a national survey of affiliates and charter members of these organizations. Respondents were asked to provide information about their programs for the 1993-1994 school year, including summer 1994 if applicable. A total of 1,234 questionnaires were mailed to the 658 youth-serving organizations in 376 cities in October 1994. Survey data were provided by 579 local affiliates. Information was collected on the type of building where the organization was located, the months, days of the week, and hours of operation, number of adults on staff, number and sex of school-age participants, number of hours participants spent at the program location, other participants served by the program, and characteristics of the neighborhood where the program was located. Questions were also asked about the types of contacts the organization had with the local police department, types of crimes that occurred at the location in the school year, number of times each crime type occurred, number of times the respondent was a victim of each crime type, if the offender was a participant, other youth, adult with the program, adult from the neighborhood, or adult stranger, actions taken by the organization because crimes occurred, and crime prevention strategies recommended and adopted by the organization. Geographic information includes the organization's stratum and FBI region.
