This report presents a statistical portrait of the demographic and socioeconomic characteristics of American youth, ages 14 to 24 years old, between the late 1960's and the early 1970's. Data are included on population growth, racial composition, distribution, and mobility; education; marital status and family composition; fertility; labor force and employment status; income; voting trends; and crime victimization. The data for this report are based largely on the results obtained in the March 1974 Current Population Survey conducted by the Bureau of Census. The sample population extends over 461 areas comprising 923 counties and independent cities with coverage in each of the 50 states and the District of Columbia. Appendixes include reliability tables of the estimates. (Author/DE)
