The Rise of Bisexuality: U.S. Representative Data Show an Increase Over Time in Bisexual Identity and Persons Reporting Sex with Both Women and Men

Abstract

ABSTRACT Recognizing that social forces shape sexual behavior and sexual identities, we examined whether the recent liberalization in attitudes toward same-sex relationships has been accompanied by changes in sexual orientation as indicated by sexual behavior and sexual orientation identity. Using nationally representative data from the General Social Survey (n = 34,524), we compared reported patterns of sexual behavior of respondents from 1989 through 2021. Among the 2012–2018 waves (n = 7144, weighted), we compared patterns of sexual orientation, as indicated by behavior and identity, among different demographic groups. We also examined how sexual behavior varied among respondents with different sexual orientations. Results showed an increase in respondents reporting both male and female partners over time, with 3.1% of respondents reporting both male and female partners since age 18 among the 1989–1994 waves, 9.3% reporting this in the 2012–2018 waves, and 9.6% reporting this in the 2021 sample. Identifying as bisexual was more common among women (3.7%) than men (1.6%) and among younger persons than older persons. Over 6% of 18–29 year-olds but fewer than 2% of respondents over age 40 identified as bisexual. Findings demonstrate that sexual norms and behaviors have changed and that far more persons today than in earlier years identify as bisexual and/or have both male and female partners.
