Today is Equal Pay Day, the day that the average woman in America has made as much as the average man did last year. With women earning anywhere from 60 to 80 percent of what white men do, our fiscal year needs extra months to make up the difference.

However, some people continue to argue that we don't have a wage gap. Instead, the discrepancy in wages between white and Asian men and all other people in America is due to motherhood. But all sorts of statistics pin the blame on far more sinister foes than babies: Looking at the hard numbers, it's undeniable that racism and sexism are a core part of American economics.

Check out these ten graphs showing how motherhood is not solely to blame for the wage gap.

1. Having a kid definitely does impact a woman's wages—but the impact isn't the same in every country. Each new kid lowers a woman's salary by 5-7 percent in America but parenting policies—like our lack of maternity leave and child care—impact income differently in each country.

2. The percent of mothers making more money than their husbands has increased dramatically. Since 1967, the number of mothers making more than their spouses has tripled. There's something going on here that doesn't just have to do with babies.

3. The wage gap persists in every single state…

4. … but it doesn't line up with birthrates. This is another sign pointing to the fact that the wage gap has to do with more than whether a woman has kids.

5. The wage gap isn't just an issue of gender and birthrates. It's an issue of race. Across the board, a person's race impacts their income. Try arguing that the gap between what Black men and white men earn is due to “the motherhood gap.”

6. Here's a chart from the American Association of University Women that shows how important it is to recognize the role of race in the pay gap. As they write, “The pay gap affects all women, but it doesn’t affect all women equally.”

7 and 8. Regardless of age or education, women earn less than their male peers. Like motherhood, age and education have an impact on earnings but are not the sole explanation for the gap. Even the best-educated workers in their prime working years earn less than men. “Among never-married, childless 22- to 30-year-old metropolitan-area workers with the same educational credentials, males out-earn females in every category,” reports the New York Times.

9. A college education helps both men and women earn more—but women are still paid less.

10. In addition to race, education, and age, the field of a person's employment affects their income greatly.

Clearly, you can't blame the wage gap just women's propensity for baby-makin'. Underlying the wage gap are big issues about what industries disproportionately employ white men, barriers to wealth accumulation, access to higher education, and straight-up racism and sexism.
