This is interesting:
I'm quoting from my Psychology textbook (which has this most interesting section about homosexuality):
"In a 2002 Gallup survey, the average American estimated that 21 percent of men are gay and 22 percent of women are lesbian (Robinson, 2002). But in both Europe and the United States, more than a dozen national surveys in the early 1990s explored sexual orientation, using methods that protected the respondent's anonymity. Their results agree in suggesting that a more accurate figure is about 3 or 5 percent of men and 1 or 2 percent of women (Laumann & others, 1994; National Center for Health Statistics, 1991; Smith 1998). Estimates derived from the sex of unmarried partners reported in the 2000 U.S. Census suggest that 2.5 percent of the population is gay or lesbian (Tarmann, 2002)."
Of course, no textbook is one-hundred percent right about things. And statistics can be somewhat misleading. As long as there are gay people who are unwilling to admit their sexual orientation, no survey is going to be truly accurate about things like this.
Anyway...just felt like sharing with you all.
