This report presents data on participation in after-school activities and programs in the United States. The data are from the After-School Programs and Activities Survey (ASPA), a nationally representative survey of the 2005 National Household Education Surveys Program (NHES:2005). The data presented in the report are based on a sample of 11,684 students in kindergarten through grade 8 representing a weighted total of 36,185,760 students. The weighted unit response rate for the ASPA survey was 84 percent; the overall unit response rate for the survey was 56 percent. Additional details about the survey, response rates, and data reliability are provided in appendix A. The purpose of this E.D. TAB is to introduce new NCES survey data through the presentation of selected descriptive information. The E.D. TAB is purely descriptive in nature. Readers are cautioned not to draw causal inferences based solely on the results presented in this E.D. TAB. It is important to note that many of the variables examined in this report are related to one another, and complex interactions and relationships have not been explored here. The variables examined here are also just a few of the variables that can be examined in these data and were selected to demonstrate the range of information that helped shape the design and now is available from the study. The selected findings are examples of comparisons that can be made using the data and are not designed to emphasize any particular issue. Release of the E.D. TAB is intended to encourage more in-depth analysis of the data, using more sophisticated statistical methods. Appended are: (1) Technical Notes; and (2) Glossary. (Contains 28 tables.)
