According to the OECD Demography and Population database, for example, in almost all European OECD countries, most immigrants are from Europe (OECD, 2018m)- Educational attainment of the native-born and foreign-born population should also inform policies related to human capital within these two groups. In some cases, similarities or divergences between the two groups can signal the need for formal and/or non-formal adult education programmes (see Indicator A7). Among 55-64 year-olds, there is a perfect gender balance in the percentage of men and women who are tertiary-educated on average across OECD countries. However, among the younger generation (age 25-34), a larger share of women than men are attaining tertiary education.
