More than half of young women in America are struggling to get through the month. That's not a metaphor. 57.3% of women aged 18 to 24 reported 14 or more poor mental health days in the past 30 days in 2024, according to BRFSS data. Their male peers weren't far behind at 44.9%, but the gap between them tells a story that runs across every age group in the survey.

The Overall Gap Has Widened Steadily Since 2016

In 2016, 29.3% of women and 21.7% of men reported frequent poor mental health days, a gap of 7.6 percentage points. By 2024, those figures had climbed to 37.7% for women and 28.5% for men, pushing the gap to 9.2 percentage points. Both sexes got worse. Women got worse faster.

From 2020 to 2023, women's rate rose from 33.1% to 36.9%, while men's climbed from 22.7% to 28.1%. That's a 3.8-point increase for women and a 5.4-point increase for men in just three years, meaning men's rates accelerated sharply in that window even as women's remained higher in absolute terms. For health systems already stretched thin, a rising floor across both sexes means the total population needing mental health support is substantially larger than it was a decade ago.

Age Reshapes the Picture Considerably

Not uniform across the lifespan, the gender gap shifts considerably by age group. Two age groups tie for the largest disparity: adults 18 to 24 and adults 45 to 54, both showing an 11.4 percentage point gap between women and men. At the younger end, that translates to 51.5% of women versus 40.0% of men reporting frequent poor mental health days (pooled across available years). At the older end, 33.2% of women versus 21.8% of men.

Adults 65 and older show the smallest gap at 7.4 percentage points, with women at 19.7% and men at 12.4%. Rates for both sexes are also lowest in this group by a wide margin. Convergence at older ages, combined with the severity of rates among younger adults, suggests the burden is concentrated in ways that have direct consequences for workforce participation, caregiving capacity, and long-term health trajectories.

Young Women's Trajectory Is the Sharpest in the Dataset

Among 18 to 24 year-olds specifically, the 2024 numbers represent a significant climb from 2016, when 44.0% of women and 35.5% of men in that age group reported frequent poor mental health days. By 2024, women in that bracket had risen to 57.3% and men to 44.9%. That's a 13.3-point increase for young women over eight years, compared to a 9.4-point increase for young men.

For context: in 2018, 38.2% of women aged 25 to 34 reported frequent poor mental health days, compared to 30.0% of men. By the time those same cohorts aged into their late 20s and early 30s, rates across the broader 25 to 34 group had climbed to 42.3% for women and 32.9% for men. The burden doesn't disappear as young adults age out of their early 20s. It follows them.

A majority of young women in the U.S. are now spending roughly half of every month in poor mental health. At 57.3%, current clinical capacity, insurance coverage, and community resources are not calibrated to that reality.
