The number of transgender people aged 13 to 17 in the U.S. is almost twice what it was in 2017, according to a report from the Williams Institute, a research institute based at the UCLA School of Law.
In 2017, the Williams Institute researchers estimated that around 0.7 percent of younger teens were transgender in the U.S., about 150,000 teens. Now, they estimate that number has doubled to 300,000.
Teens and young adults make up a much larger portion of the transgender population compared to adults. About 43% of the 1.6 million transgender people in the U.S. are young adults or teenagers, and nearly one in five are minors ages 13 to 17. This is despite the younger teen demographic being less than 8% of the total U.S. population. In the same vein, young adults 18 to 24 make up just under a quarter of the transgender population, but they are only 11% of the total U.S. population.
