Three Percent Gay, Half a Percent Trans

I have been looking for some reasonable estimates of the proportion of the population who are homosexual, and of those who are transgender.

Edward Laumann and his University of Chicago team established the now-standard estimate that 2 - 4% of men, and 1 - 3% of women have a same-sex orientation, which averages to about 3% of the population.

The first efforts are being made now to estimate the proportion who are transgender.  The first reports, based on state-wide surveys in California and Massachusetts, were .3%.  Are more recent study of 19 states found .52% said they were transgender, which the authors round up to .6%

The wheel is still in spin here, so these early estimates will likely be modified by later research.
