Jean M. Twenge has concluded that non-heterosexual identity is in free fall among U.S. young adults, based on newly available nationally representative data. Her analysis, published on November 5, 2025, and updated in a follow-up post on March 3, 2026, shows a significant decline in self-identification as lesbian, gay, or bisexual (LGB) among young adults, with bisexual women showing the largest drop. This trend appears to be part of a broader shift, as Twenge also found sharp declines in transgender and nonbinary identity among 18- to 22-year-olds and teens as young as 13. She attributes the drop to possible changes in social acceptance, mental health improvements, or a fading of social trends, though she cautions that long-term patterns will only be clear with future data. Her findings are based on the Cooperative Election Study (CES) and the Monitoring the Future survey, though some researchers have questioned the use of statistical weights in the analysis.
