Information on educational attainment of the U.S. population has been collected in every decennial census since 1940. At a national level, reports show rates of educational attainment by age, sex, race, and Hispanic origin. Differing at the regional and state levels, educational attainment data are shown by sex, race, and Hispanic origin (not age).

Overall, the demographics with the highest educational attainment in the United States are also those with the highest household income and wealth.

General attainment of degrees/diplomas

These categories report each person's highest level of attainment and therefore are not cumulative.

In 2018, nearly 9/10 (90 percent) of all adults 25 years or older reported they had completed at least high school, or obtained a GED/high school equivalency certificate. Over one in three adults (35 percent) had attained at least a bachelor's degree. Both of these measures are all time highs. In 2003, the percentage of the adult population who had completed high school or had not completed high school but obtained a GED increased for the first time since 2000, when it was 84 percent. This increase follows a general trend that the Current Population Survey has shown since educational attainment was first measured in 1947.

Since 1983, the percentage of people either graduating from high school or failing to complete high school but getting a GED certification has increased from 85% to 90%. The greatest increases in educational attainment were documented in the 1950s, 60s, and 70s. In the 1950s and much of the 1960s high school graduates constituted about 50% of those considered adults (25 and above). For adults aged between 25 and 30, the percentage of either high school graduates or GED obtainers was roughly 50% in 1950 versus 90% today.

According to the United States Census Bureau, from 1940 to 1980, respondents were asked to what their highest grade or year of school completed was. Here are two examples of the questions asked:

  1. What is the highest grade (or year) of school this person has ever attended?
  2. Did he finish the highest grade (or year) he attended?

The answers consisted mostly of the following:

  • No school completed or never attended school
  • Nursery school (added as a choice in 1960)
  • Elementary school, grades 1, 2, 3, etc. to 8
  • High school 1st to 4th year…1, 2, 3, 4
  • College, 1st year, 2nd year, etc.

However, in 1990, the Census Bureau changed educational attainment question as society became more educated as a whole. Now, respondents are asked to report what their highest level of school/highest degree received is. Responses may include; "High school graduate" and "Bachelor's degree."
