Cohort Differences in Sexual Orientation: Results from a Large Age-Statified Population Sample

Abstract

Background: There is some community survey evidence for a cohort difference in female sexual orientation. Objective: To determine whether there is a cohort difference in sexual orientation in Australia. Methods: A community survey was carried out with a sample of 7,447 adults from the age groups 20-24, 40-44 and 60-64 years. As part of this survey respondents were asked a question on sexual orientation which was answered privately. Results: A strong age cohort difference was found for women, with younger women more frequently reporting a homosexual or bisexual orientation. By contrast, no age cohort difference was found for men. Conclusion: These findings suggest that a heterosexual orientation may have become less common in younger cohorts of Australian women. This finding is consistent with data from other recent studies. Show more
