ABSTRACT
This paper
reports trends in educational assortative marriage from 1940
to 2003 in the United States. Analyses of Census and Current
Population Survey data show that educational homogamy
decreased from 1940 to 1960 but increased from 1960 to 2003.
From 1960 to the early-1970s, increases in educational
homogamy were generated by decreasing intermarriage among
groups of relatively well educated persons. College
graduates, in particular, were increasingly likely to marry
each other rather than those with less education. Beginning
in the early-1970s, however, continued increases in the odds
of educational homogamy were generated by decreases in
intermarriage at both ends the education distribution. Most
striking is the decline in odds that those with very low
levels of education marry up. Intermarriage between college
graduates and those with “some college” continued to decline
but at a more gradual pace. As intermarriage declined at the
extremes of the education distribution, intermarriage among
those in the middle portion of the distribution increased.
These trends, which are similar for a broad cross-section of
married couples and for newlyweds, are consistent with the
growing economic and cultural divide between those with very
low levels of education and those with more education in the
U.S.
