Information on educational attainment of the U.S. population has been collected in every decennial census since 1940.  In 1940, educational attainment was collected for every person enumerated in the census (i.e., 100% data) and on a sample basis thereafter.  At the national level, this report includes tables that show rates of educational attainment by age, sex, race, and Hispanic origin.  At the regional and state levels, educational attainment data are shown by sex, race, and Hispanic origin.  The tables show two attainment levels:  the percent of the population 25 years and over with a high school diploma or more education and the percent with a bachelor’s degree or more.
