The latest Gallup poll released Thursday finds a new high of 9.3% of adults identified as lesbian, gay, bisexual, transgender or something other than heterosexual in 2024.

The polling company said the share of LGBTQ adults is up from 7.6% in 2023, has nearly doubled since 2020, and has almost tripled from 3.5% in 2012 when it first posed the question in surveys.

Gallup chalked up the trend to an uptick in younger, liberal women identifying as bisexual during the years of the Biden administration.

“The recent increase is largely due to more adults in their late teens, 20s and 30s — particularly young women — saying they are bisexual,” said Jeffrey M. Jones, Gallup’s senior editor. “But younger adults are also more likely than older adults to identify as lesbian, gay, transgender or other nonheterosexual orientations.”

Mr. Jones said the rate “is likely to continue to grow, given the generational shifts underway.”

The poll found that more than one in five Generation Z adults born between 1997 and 2006 were LGBTQ. That share dropped steadily among older generations as age increased, from 14.2% of millennials born between 1981 and 1996 to 1.8% of Silent Generation adults born before 1946.

Identification among Gen Z accelerated during the last two years of the Biden administration, from an average of 18.8% of Gen Z adults in 2020 through 2022 to an average of 22.7% from 2022 to 2024. Over the same period, it increased by 2% for millennials and 1% for Generation X but did not change among those born before 1965.

The survey found that LGBTQ identification last year was highest among liberals (21%), Democrats (14%), women (10%) and urban residents (11%). Just 3% of Republicans and conservatives, 6% of men and 7% of rural residents said the same.

Gallup conducted a randomized national telephone survey of 14,162 adults throughout 2024. The margin of error was plus or minus 1 percentage point at the 95% confidence level.
