This is going to be tricky. I’m just trying to find out what percentage of the population was gay in 1991.
The American National Health Interview Survey conducts household interviews of the civilian non-institutionalized population. The results of three of these surveys, done in 1990–91 and based on over 9,000 responses each time, found between 2% and 3% of the people responding said yes to a set of statements which included “You are a man who has had sex with another man at some time since 1977, even one time.”[23]

That’s just asking if they’d had sex with a man. You can have sex with a man and not be gay and you can be gay and not have had sex with a man.
Still… I don’t think that’s too far off from the general population and it’s no cause for alarm.
