Overview

• The Williams Institute’s August 2025 report estimates about 2.8 million people ages 13 and older—roughly 1% of that population—identify as transgender.
• Youth account for a disproportionate share: approximately 3.3% of 13–17-year-olds (about 724,000 teens) identify as transgender, and over 75% of those 13+ who do so are under 35.
• Among adults, roughly 2.1 million identify as transgender, with a near-even split among transgender men (34.2%), transgender women (32.7%) and nonbinary people (33.1%), and the adult share is described as fairly consistent over time.
• The analysis uses CDC-administered Behavioral Risk Factor Surveillance System (2021–2023) and Youth Risk Behavior Surveillance System (2021, 2023) data to produce national and state estimates.
• State patterns vary: Minnesota is estimated to have the highest percentage of transgender adults (1.2% of 18+), while Hawaii has the highest percentage of transgender youths (3.6% of ages 13–17), and the report flags uncertainty about future estimates due to reduced federal data collection.
