Unlike the extensive cross-national research on occupational sex segregatio
n, sex segregation within higher education has yet to be empirically examin
ed comparatively. This article reports analyses for a wide range of countri
es from 1965 through 1990, using two measures of gender differentiation by
field of study. The results indicate that gender differentiation has declin
ed surprisingly little. Women are more likely to graduate from education, a
rts, humanities, social sciences, and law, and men are more likely to gradu
ate from natural sciences, mathematics, and engineering. Few differences ar
e found between more- and less economically developed countries. These find
ings echo those in the occupational sex segregation literature.
