There have been scientific studies way back in the 1970's and 80's by Kinsey and Johnson. Through extensive interviews it was noted about one in ten men identified as homosexual while one in a hundred identified as crossdressers. That would indicate that there are roughly 1,540,000 crossdressers in the United States. This group is a biased sample and would seem to skew any opinions on the issue. Since the studies were extensive, intensive as well as longitudinal there is no reason to think that the percentages have increased dramatically. Karan
