The U.S. Office of Education and the Bureau of the Census conducted a joint nationwide study of the people who engaged in adult education activities. By attaching a 12-question Adult Education Supplement to the May 1969 Current Population Survey (CPS), information was obtained about both adult education and the characteristics of the people who do and do not take adult education. This initial report presents the data obtained from the sample of the national population who responded to the three questions which the Census Bureau interviewers used to identify persons eligible to be asked the 12 questions in the Adult Education Supplement. These three questions dealt with age, full-time study, and instructional sources. Responses to the 12-part questionnaire will be published in a subsequent report. The statistics presented here were obtained from the household spokesman for individual persons. This report is one that shows multiple participation in various kinds of sources of adult education. The figures presented are based on the scientifically selected representative sample (approximately 105,000 people) used by the Bureau of the Census for national labor force estimates for the monthly CPS.
