Bisexual identification peaked, then fell

Federal survey data show the share of U.S. women ages 18–24 reporting bisexuality rose from about 8% (2014–15) to roughly 23% in 2022, then dropped to under 18% by 2025, suggesting rapid cohort‑level shifts rather than monotonic increases. Pairing these identity trends with monthly CDC mortality counts for ages 15–44 provides a way to test whether cultural reversals correlate with changes in youth health outcomes. — If sexual‑identity self‑reports can surge and then recede within a few years, that changes how policymakers and institutions interpret cohort surveys, design youth services, and attribute causes for youth mental‑health trends.
