This one says 20%, according to polls...

Kinsey said 10% : https://www.hli.org/resources/prevalence-of-homosexuality-in...

5% is low, then, for some. But it's far more than OP's 1%, which was my point.

Different statistic altogether, but ~17% of Gen Z self-reports as lgbt in Gallup surveys: https://www.washingtonpost.com/dc-md-va/2021/02/24/gen-z-lgb...

This is most likely increases in "B", less "LGT", though I expect all to increase given the reduction in stigma.

Vast majority of new cases of "B" are likely to be cultural. i.e. White women in HS/Uni. Declared, but never expressed.

as a gen z, there's a considerable fraction of mostly girls who identify as bi or nb just bc it's "trendy". tbh it's a problem and lowkey trivializes people who actually are those. i think this is what happens when you emphasize a "lgbt community", young people seeking community will join for no other reason.
