The number of Americans who identify as lesbian, gay, bisexual, or transgender has risen once again. Last year, 4.5 percent of adults surveyed by Gallup said they identified as LGBT, up from 4.1 percent in 2016 and 3.5 percent in 2012. That translates to more than 11 million Americans.
The survey found that the increase has been happening most rapidly among millennials, while the share of LGBT individuals in older generations has remained nearly steady. While 8.1 percent of millennials identified as LGBT last year, just 2.4 percent of baby boomers did. Between 2016 and 2017, the number of LGBT millennials went up by nearly a full percentage point, the biggest increase ever tracked by Gallup.
More women identify as LGBT than men, with 5.1 percent of women and 3.9 percent of men self-identifying as such. The survey also found larger upticks among Hispanic respondents, while white respondents were least likely to identify as LGBT.
The study surveyed 340,604 U.S. adults reached by phone between Jan. 2 and Dec. 30, 2017. It has a margin of error of plus or minus 0.1 percentage point. See more results at Gallup.
