Education Matters: Earnings by Educational
Attainment Over Three Decades
Linda Levine
Specialist in Labor Economics

The amount of education that individuals accumulate has an important influence on
their experience in the labor market. Workers with more years of education typically
encounter less unemployment. Conversely, as educational attainment increases, earnings
typically rise. These relationships have held up over time, and in some periods, have
intensified. College graduates’ earnings grew so much more rapidly than those of less
educated workers during the 1980s, for example, that it prompted ongoing interest in the
extent of wage inequality among U.S. workers.1
Workers with a bachelor’s degree are much better off today, compared to less
educated workers, than they were some three decades ago. As shown in Table 1, the
average wage advantage of male college graduates over male high school graduates grew
from about 50% in the latter half of the 1970s to at least 90% thus far in the current
decade. The average premium paid to female college over female high school graduates
similarly increased, going from about 40% to about 80% during the same period.
Workers with the least education generally have experienced the slowest wage
growth. This has been particularly true for men. Weakness in comparatively high-paid
male-dominated industries in which many jobs typically require 12 or fewer years of
schooling (e.g., manufacturing) likely explains some of the relatively meager wage gains
among less educated men.
Over the years, women’s wages have increased to a much greater degree than men’s
wages at each educational level. Nonetheless, men who lack high school diplomas
continue to earn slightly more than female high school graduates and slightly less than
women who have some postsecondary education.2
These one-year earnings differences by education level are estimated to produce
markedly wider disparities over an individual’s working life. Among full-time year-round

workers, high school dropouts might have average earnings totaling $1.0 million (in 1999
dollars) over a 40-year working life; high school graduates, $1.2 million; those with some
college or an associate’s degree, $1.5-$1.6 million; and college graduates, $2.1 million.3
