The percentage of US adults who report having or being treated for depression has exceeded 18% in both 2024 and 2025, up about 8% since the initial measurement in 2015. The current rate of 18.3% measured so far in 2025 projects to an estimated 47.8 million Americans suffering from depression. Most of the increase has occurred since the onset of the COVID-19 pandemic in 2020. Depression rates have risen dramatically since 2017 among adults under the age of 30, doubling from 13.0% in 2017 to 26.7% in 2025. The current estimate is up from 24.6% measured in 2023, indicating that depression continues to be a worsening problem among young adults. Among those in households earning under $24,000 per year, reports of depression have risen from 22.1% in 2017 to 26.1% in 2023 to 35.1% now, a 13-point increase in eight years. The change for these lower-earning Americans is particularly notable given the nine-point increase since 2023.
