(OPINION) The percent of U.S. adults who identify as something other than heterosexual has doubled over the last 10 years, from 3.5 percent in 2012 to 7.1 percent, according to a Gallup poll released Thursday.

Gallup found that the increase is due to ​​”high LGBT self-identification, particularly as bisexual, among Generation Z adults,” who are 18 to 25. It asked more than 12,000 U.S. adults how they identify during telephone interviews last year. It found that younger U.S. adults are much more likely to identify as LGBTQ than older generations.

More than 1 in 5, or 21 percent, of Generation Z adults identify as LGBTQ, Gallup found. That’s almost double the proportion of millennials, who are 26 to 41, at 10.5 percent, and nearly five times the proportion of Generation X, who are 42 to 57, at 4.2 percent. Less than 3 percent of baby boomers, who are 58 to 76, identify as LGBTQ, compared to just 0.8 percent of traditionalists, who are 77 or older.

As the youngest Americans slowly outnumber and replace the oldest, Gallup predicts the number of LGBTQ-identifying adults will only increase — and likely at a much faster rate than past generations. The poll found that the percent of Generation X, baby boomers, and traditionalists who identify as queer has remained relatively the same over the years.

More millennials have increasingly identified as LGBTQ, but only slightly, at 5.8 percent in 2012, 7.8 percent in 2017, and 10.5 percent now. But the poll noted that the percentage of Generation Z adults who are queer has almost doubled since 2017 — jumping from 10.5 percent in 2017 to 20.8 percent. The rise shows that younger Gen Zers, who have turned 18 since 2017, are more likely than older Gen Zers to identify as queer. READ MORE
