Okajuurou saidI don't know about USA, I think it should be about the same as in Canada.No because the US has a much larger population than Canada. I would say that gays are between 5% and 7% of the US population. Canada would be more similar to Australia which also has a much smaller population than the US.
Here the citation about gay population from CanadaStat:
"1.1% — The percentage of Canadians aged 18 to 59 who reported in 2009 that they consider themselves to be homosexual (gay or lesbian)".
Percentages wouldn't change due to population base. Total/gross numbers would.
Depending on the definition of 'gay' and the samples surveyed, there have been studies which say anywhere from 2% to 10%.
There tends to be two types of survey definitions:
(A) Ever (even just one instance) of consensual male to male sex
(B) Self-identify as gay/bi/lesbian
These tend toward different results, as you would intuit by the survey question. With stigma still attached to same-sex sexuality and attraction, the (B) percentage will be lower. The (A) definition would include gay / bi curious people and ex-gays and is a more inclusive definition as it focuses on sex acts and not necessarily sexuality.
The (A) definition is what public health and policy experts will tend toward as they are more curious and more responsive to public health concerns. The (A) definition is what the gay-stigmatizing conservative organizations tend to use.
Kinsey Reports from the mid 20th C. are also good to look at in that Kinsey and friends made light of the fact that it's not a "once and therefore flaming" kinda experience and that sexuality may change over time. It is a bit more nuanced.http://en.wikipedia.org/wiki/Kinsey_Reports
