Increase in LGBQ+ individuals

It appears that there is an increase in people tha identify as LGBQ+ lately. Do you think this is due to:
1. There is no actual increase in people that are not heterosexual, it's just that people feel safer to come out/ it's more socially accepted now.
Or
2. More people are claiming to be LGBQ+ because it is trendy.
