Indeed, more young women than ever before are now participating in formal and higher education in the OECD and, over the past decade, gender gaps in educational attainment have reversed. In 2000, adult men had higher tertiary-level attainment rates than adult women, but by 2012 34% of women across OECD countries had attained a tertiary education, compared with 30% of men. Among the over 100 non-OECD countries that are part of the Barro and Lee dataset (2013), the average number of years that working-age adults spend in education countries rose from around two to about eight among men and from one to eight years for women.
