This trend also holds in the United States, where the gender gap in employment is particularly high among 25-64 year-olds with below upper secondary education. For this age group, the employment rate is 67% for men and 40% for women, a difference of 27 percentage points, compared to the average difference of 20 percentage points across OECD countries. The gender gap in employment in the United States shrinks to 13 percentage points for adults with upper secondary or post-secondary non-tertiary education and to 9 percentage points for adults with tertiary education.
