Gender Expression and Its Correlates in a Nationally Representative Sample of the U.S. Adult Population: Findings from the National Survey of Sexual Health and Behavior.

We explored the associations of gender expression with childhood gender expression, sexual identity, and demographic characteristics in a representative sample of the U.S. population aged 18 to 65 years (N = 1277), using data from the 2015 National Survey of Sexual Health and Behavior. As expected, gay men were less gender conforming than heterosexual men. However, among women, persons with a bisexual identity were less gender conforming compared to heterosexual and lesbian persons. In multivariate analyses, childhood gender expression trumped the role of sexual identity. In terms of demographic characteristics, gender conformity seemed to be more present among persons with positions with less social status in terms of age, race/ethnicity, education, income, and relationship status. Finally, we found among both men and women, that a large proportion saw themselves as more masculine or feminine than men and women on average, respectively, suggesting that accentuating one's gender conformity has a psychological function.
