Paisley, It seems pretty clear to me that the only correct answer (for the US) is "there are no reliable national surveys which document the size of the trans population." And *most* especially when you consider that the definition of "trans" is so elastic (even if we assume that means "TS or what some people would cll TS") that even with perfect information, the answer could easily vary by an order of magnitude, depending on which definition you're interested in. If we include "trans-anything", then the definitions become so outrageously variable, that you could cover several orders of magnitude with changing definitions. But if anyone knows of anything remotely approaching accurate figures for the US, I, too, would be very glad to know of it. Steve %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
