The percentage of gays in a country is a notoriously difficult statistic to determine. People aren't always forthcoming to survey-takers, and the very definition of "gay" is slippery. Are you a lesbian if you got drunk once and made out with your sorority sister? Some gay activists say yes, even if you self-identify as having found the experience singularly revolting.
Finally, I can put this issue to rest. The percentage of gays is exactly 8%.
