This report contains a summary of descriptive information about 1980 seniors two years after leaving high school--their educational, vocational, socioeconomic, and familial status and their plans and attitudes. Chapter I is an introduction to the High School and Beyond (HS&B) longitudinal surveys. Chapter II indicates the percentages of male and female 1980 seniors participating in postsecondary education, work, and other activities in October 1980 and October 1981. Chapter III studies the entry rates--immediate and delayed--of 1980 seniors into postsecondary institutions, examines the rate of persistence of those who went to college as well as their major fields of study, and describes the kinds and amounts of financial aid received. Chapter IV describes labor force experiences--employment status and earnings. Military service is the focus of chapter V, while chapter VI notes family formation statistics and chapter VII addresses the changes that had taken place since the students' senior year in values, attitudes, and opinions. Appendix A presents a description of HS&B data files available for public use; appendix B defines the variables that were used to divide the total population into subgroups; and appendix C discusses the HS&B sample design and the quality of the data. (Thirteen tables are provided.) (YLB)
