Almost 55% of the respondents identified as bisexual. Another 24.5% identified as gay with 11.7% identifying as lesbian and 11.3% as transgender.
The survey extended a trend of younger generations identifying as other than heterosexual. The highest proportion was among Generation Z, whose oldest members were 18-23 in 2020. One in six said they were not heterosexual.
