According to Pew Research:
“About 10 million people, or 4.1% of the U.S. adult population, identified as LGBT
LGBT = homosexual men and women, homosexual heterosexuals and people who have in psychology another gender than in biology.
2016, according to the latest estimates from
Gallup. This represents a modest but significant increase from 8.3 million people (3.5% of adults) who said they were LGBT in 2012.“
Obviously, many LGBT people don’t “come out”, so the real figure may be double or triple the 4% figure.

It existed lots of problems everywhere in all families and the whole society. Lots of psychological problems too. But gender was not a big problem (homosexuality, bisexuality). A transvestite had some problems because the people did not accept his outfit. I remember I spoke a whole afternoon with him/her about - but this was not the only time I met him/her.
I would classify the sciences into 3 main categories:
PHYSICAL: Physics & Chemistry;
BIOLOGICAL: When cells & DNA replicate;
SOCIAL: When organisms adapt to each other as well as their physical/biological ecology, with “conscious processes” involved.
Hierarchy of science:
[logos ->] physics -> chemistry -> biology -> psychology = > spirituality, culture (civilization) and society => [logic, mathematics] =>> science of physics -> science of …
