The percentage of U.S. adults who self-identify as lesbian, gay, bisexual, transgender or something other than heterosexual has increased to a new high of 7.1%, which is double the percentage from 2012, when Gallup first measured it.
Gallup asks Americans whether they personally identify as straight or heterosexual, lesbian, gay, bisexual, or transgender as part of the demographic information it collects on all U.S. telephone surveys. Respondents can also volunteer any other sexual orientation or gender identity they prefer. In addition to the 7.1% of U.S. adults who consider themselves to be an LGBT identity, 86.3% say they are straight or heterosexual, and 6.6% do not offer an opinion. The results are based on aggregated 2021 data, encompassing interviews with more than 12,000 U.S. adults.
The increase in LGBT identification in recent years largely reflects the higher prevalence of such identities among the youngest U.S. adults compared with the older generations they are replacing in the U.S. adult population.
Roughly 21% of Generation Z Americans who have reached adulthood — those born between 1997 and 2003 — identify as LGBT. That is nearly double the proportion of millennials who do so, while the gap widens even further when compared with older generations.
Since Gallup began measuring LGBT identification in 2012, the percentage of traditionalists, baby boomers, and Generation X adults who identify as LGBT has held relatively steady. At the same time, there has been a modest uptick among millennials, from 5.8% in 2012 (when some members of the generation had not yet turned 18) to 7.8% in 2017 and 10.5% currently.
The percentage of Gen Z who are LGBT has nearly doubled since 2017, when only the leading edge of that generation — those born between 1997 and 1999 — had reached adulthood. At that time, 10.5% of the small slice of the generation who were adults identified as LGBT.
