Most people grasp the fundamentals of the gender pay gap: Women working full-time earn roughly 80 percent of men’s salaries. But beyond the basics are some fascinating facts you may not have heard before. Check out these findings from the American Association of University Women (AAUW).

1. Mothers, including those who never left the workforce, get paid less than other women.

2. When women enter a traditionally male-dominated occupation, wages go down in that field, even for men.

3. Transitioning genders affects how people are paid.

4. The pay gap widens as women get older.

5. Latinas have the widest pay gap.

6. Women carry more student debt than men.

7. Women are less likely to negotiate than men, and less confident when doing so.

8. There is only one job where women typically earn more than men.
