Girls within the U.S. in most cases earned 85% up to males for each hour they spent running in 2024. Then again, running girls are faring significantly better than their mothers and grandmothers did 40 years in the past. Within the mid-Nineteen Eighties, girls had been making most effective 65% up to males for each hour of paid paintings.
Girls’s wages have advanced relative to what males earn partially as a result of beneficial properties of their training and paintings revel in, and since girls have moved into higher-paying occupations. However growth towards pay equality has stalled.
As sociologists and demographers, we would have liked to understand whether or not adjustments in American households may also have helped girls come nearer to pay equality with males. In an editorial printed in June 2025 in Social Forces, an educational magazine, we argued that this pay hole is changing into smaller partially as a result of girls are having fewer kids.
Mothers earn much less however dads earn extra
Within the U.S. and in different places, abundant proof presentations that parenthood impacts males’s and ladies’s wages in a different way.
In comparison to final childless, motherhood ends up in salary losses for ladies. And the ones losses are better when girls have extra youngsters.
Against this, after males develop into fathers their wages typically upward thrust.
As a result of having youngsters has a tendency to push girls’s wages down and males’s wages up, parenthood widens the gender pay hole.
When males have youngsters, it doesn’t depress their wages how it does for ladies.

Decline in beginning price performs a task
American citizens are having fewer youngsters basically. Girls, together with those that don’t paintings outdoor the house, had a median of about 3 kids through their 40s in 1980. By way of 2000, that moderate had fallen to one.9, and it’s been quite solid since then.
To peer whether or not adjustments in what number of youngsters running American mothers have impacts what they earn relative to males, we analyzed knowledge gathered from a nationally consultant pattern of U.S. households. We tracked tendencies through the years within the collection of kids that hired American citizens ages 30-55 have.
We discovered that workers’ moderate collection of kids fell considerably between 1980 and 2000, declining from round 2.4 to round 1.8. That moderate stabilized after 2000; workers had a median of about 1.8 kids in 2018 – the latest 12 months in our research.
On the identical time, the pay that ladies on this age vary earned in keeping with hour relative to males rose steeply. It climbed from 58% in 1980 to 69% through 1990 after which rose extra steadily to 76% through 2018. This is, as other people had been having fewer youngsters, the gender pay hole were given smaller. For each tendencies, there used to be speedy exchange within the Nineteen Eighties, adopted through slower exchange after 1990.
We subsequent estimated whether or not declines within the collection of kids women and men have can give an explanation for the narrowing of the gender pay hole between 1980 and 2018.
We discovered that, even after adjusting for different components, comparable to years of training, prior paintings revel in and career, about 8% of the decline within the gender pay hole may also be defined through the decrease collection of kids running men and women are having.
Subsequent, we confirmed that the collection of kids American workers had declined sooner within the Nineteen Eighties than afterward. That slowdown coincided with a deceleration of girls’s beneficial properties in pay relative to males. As soon as the typical collection of kids that U.S. workers had stabilized round 2000, so did girls’s growth towards incomes up to males.
Questions on the way forward for US fertility
U.S. students and policymakers are debating whether or not and why American citizens are having fewer kids as of late than one or 20 years in the past, and what the federal government will have to do about it.
We agree that those are vital questions.
Our analysis presentations that any long term adjustments in what number of kids American citizens have are very more likely to impact how temporarily men and women succeed in pay equality. But it surely’s no longer inevitable.
The collection of kids American citizens have impacts the gender pay hole most effective as a result of parenthood decreases girls’s wages whilst expanding males’s wages. So long as those unequal results of parenthood on what women and men earn persist, they’ll proceed to behave as a brake on girls’s growth towards equivalent pay.
