Educational attainment in the United States, 1940-2009

In the United States, the level of education of the adult population has increased steadily since the middle of the 20th century. The share of the population 25 years and over who attended college increased from 10 percent in 1940 to 56 percent in 2009. 30 percent of the population in this age group had completed 4 or more years of college in 2009. The share of the population with only elementary education or no formal schooling fell from 60 percent in 1940 to 6 percent in 2009. High school reached its peak as the most common level of education in the 1970s and 1980s, with a share around 50 percent, but younger cohorts are more likely to continue their education at the post-secondary level.

This increase in educational attainment of the work force has contributed to a strengthening of U.S. competitiveness in the global economy. At the same time, the increased demand for highly skilled workers emphasizes the importance of secondary and higher education for individuals in search of employment.

The trends in years of schooling of the adult U.S. population from 1940 to 2009 are visualized in the figure below. The table that follows lists data for selected years. The data on educational attainment were collected with the Current Population Survey (CPS), a joint survey by the Bureau of Labor Statistics and the Census Bureau that has been conducted since 1940.

Achievement gap between black and white students in the United States

Two previous articles on this site presented data on disparities in school attendance by ethnicity, language or religion from 17 nationally representative household surveys. Net attendance rates among the least disadvantaged groups are up to 1.7 times higher than net attendance rates among the most disadvantaged groups at the primary level of education and up to 6 times higher at the secondary level of education.

Similar gaps in access to education and in student achievement exist in the United States. The National Center for Education Statistics has published the most recent findings of its National Assessment of Educational Progress, a long term study of student achievement, in the report NAEP 2008 Trends in Academic Progress. The results of the periodic assessments by the NCES demonstrate a persistent achievement gap between black and white students.

Figure 1 summarizes the results of 12 reading assessments over the period 1971 to 2008. For each assessment, the average reading scores of black and white students aged 9, 13 and 17 years are plotted in the graph. The shaded area indicates the achievement gap between black and white students. For 2004, two scores are shown for each group because the assessment format was revised in that year. The reading scores in 1971 and 2008 are also listed in Table 1.

Black and white students of all ages achieved higher reading scores in 2008 than in previous years. In 1971, 9-year-old white students had an average score of 214 and black students in the same age group scored 170 on average. In 2008, the average score of 9-year-olds was 228 for white students and 204 for black students. As a result, the score gap between black and white 9-year-olds fell from 44 in 1971 to 24 in 2008. For 13-year-old students the score gap fell from 39 to 21 over the same period and for 17-year-olds it fell from 52 to 29.

Closer inspection of the data reveals that most of this reduction in the achievement gap occurred during the 1970s and 1980s. Since the 1990s, the gap between black and white students has remained relatively stable. Although the reading scores of black students continue to improve, they no longer grow fast enough to close the gap with white students.

Black White
1971 9 years 170 214 44
2008 9 years 204 228 24
1971 13 years 222 261 39
2008 13 years 247 268 21
1971 17 years 239 291 52
2008 17 years 266 295 29

The NAEP report shows a similar achievement gap between black and white students in the area of mathematics. In addition, there is a similar but smaller gap between white and Hispanic students in reading and mathematics. In spite of long-running efforts to improve the education system for all parts of the population, minority students consistently lag behind white students in the United States.
