Between 2007 and 2017, the number of transgender youth clinics in the US went from 1 to at least 41 – and the number continues to increase

A 2017 paper¹ notes that:

The first transgender youth clinic in the United States opened in Boston in 2007. Since then, 40 other clinics have opened that cater exclusively to children, with new clinic openings being announced frequently.
