A number of searching studies on transsexualism have been published during recent years (Roth and Ball, 1964; Benjamin, 1966; Wålinder, 1967). In the present paper we shall attempt to demonstrate that transsexualism has another direct social consequence besides the large risk of suicide which one of us has already demonstrated (Wålinder, 1967). Our study was prompted by our experience that transsexuals change their address unusually often in comparison with others.
