An estimated 14,550 people in the District of Columbia identify as transgender, or 2.77 percent of the population, according to a study by UCLA’s Williams Institute.

The study, which was first reported by NPR, used data from an annual Centers for Disease Control survey. It found that roughly 0.6 percent of American adults identify as transgender—double a previous estimate. Aside from D.C., which is an uneven comparison because it an urban area, Hawaii had the highest percentage at 0.8 percent. The study also broke the data down by age, consistently finding that the youngest group (18-24) had the highest percentage of people identifying as transgender.

While D.C. has robust protections in place and a strong transgender community, major hurdles still remain. A first-of-its-kind study, for example, found that nearly half of D.C. employers preferred a less-qualified cisgender applicant to a more-qualified candidate they perceive as transgender. And earlier this year, a security guard assaulted a transgender woman who was trying to use a bathroom at a supermarket.
