This report presents educational attainment and income data for selected years from 1956 to 1966 assembled from information collected in the Current Population Survey.¹ Included in the report are annual mean income and estimates of expected lifetime income for men by educational category and age class, standardized estimates of 1966 annual mean income, and an analysis of the income figures with special emphasis on both the past and prospective income changes for men with common birth periods or cohorts, e.g., those born between 1922 and 1931. Other information in this report includes an examination of the assumptions and procedures used to prepare lifetime income estimates, definitions and explanations of terms, sources of data, and selected references pertaining to lifetime income. Some of the selected references, such as the article of B. F. Kiker, "The Historical Roots of the Concept of Human Capital," contain bibliographies useful in studying the concepts and developments associated with the subject of lifetime income.
