The report describes and analyzes data collected through personal interviews of a national random sample of 5,167 individuals trained in 1969 under the Manpower Development and Training Act. A description is given of the trainees' personal characteristics, their household environment, their view of the training experience, and changes they experienced in hourly wages, employment and annual incomes. Analytically, a multi-variate analysis helped to identify which enrollee characteristics were most important in determining economic outcomes. Non-interview data were gathered to assess the general economic environment of each training site and to measure independently the change in employment and income of each enrollee to assess interviewee response bias.
