This report updates the information in Series P-60, No. 56, "Annual Mean Income, Lifetime Income, and Educational Attainment of Men in the United States, for Selected Years, 1956 to 1966," which was published in August 1968. In addition, this report includes for the first time estimates on lifetime income of male year-round full-time workers. The estimates are based on data for 1967 and 1968. Other information presented includes the procedures used to prepare estimated lifetime incomes, definitions and explanations of terms, and sources of data.
In the P-60, No. 56 report, lifetime incomes were computed based on grouped data. However, improved methodology introduced in 1967 permits the computation of data based on actual reported amounts. Therefore, lifetime income estimates and mean incomes of men for the years 1967 and 1968 are based on both grouped and ungrouped data to help bridge the gap in the data computed by the two estimation procedures. For consistency, comparisons of annual income statistics in this report are made on the basis of grouped data.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
