Transgender population in the US
Just like the overall population, the transgender population varies greatly across the states, with the most populous states, such as California, Texas and Florida, having the highest numbers of persons identifying as transgender. This recent data from the Williams Institute January 2017 study, “Age of Individuals Who Identify as Transgender in the United States” utilizes data from the CDC’s behavioral Risk Factor Surveillance System (BRFSS) to estimate the percentage and number of youth and adults who identify as transgender nationally and in all 50 states. This data also provides nationwide estimates of Americans who identify as transgender by age group, with estimates ranging from .5% of the population for Americans 65 and over to .7% for Americans ages 13-24.
