In 2023, 27.1% of US young adults aged 18–34 years (about 19.9 million people) reported multiple chronic conditions (2 or more).
Notes on verification
Confirmed by CDC's own publication (Watson et al., Prev Chronic Dis 2025;22:240539) and corroborated by PubMed/PMC versions of the same study, matching both the 27.1% figure and 19.9 million population estimate. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
