There have been no studies aimed at estimating the total number of people who have some form of GID. The best studies have concentrated on diagnosed, post-operative transsexuals. The American Psychiatric Association (APA) publishes the frequency for male-to-female transsexuals who have undergone surgery at 1 in 30,000 and female-to-male at 1 in 100,000.
