This report presents detailed statistics for the United States and regions on the educational attainment of the population 14 years old and over in terms of years of school completed classified by various demographic, social, and economic characteristics. The statistics are based on the 1970 Census of Population.
The text consists of an introduction and Appendices A through E, which appear after the tables.
Content of the Tables. Tables 1 to 11 present cross-classifications of years of school completed by characteristics such as ethnic origin, marital status, labor force status, occupation, and income. Statistics are shown for regions and by type of residence; i.e., urban and rural and inside or outside central cities of urbanized areas. To facilitate comparisons of changes in the social and economic characteristics over time, all tables in this report show years of school completed cross-classified by age.
Sample size. The statistics in this report are based on a sample inflated to represent the total population. Table 1 is based on the 15-percent sample and the remaining tables are based on the 5-percent sample (see "Data Collection Procedures" in Appendix A).
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.
