What does the data say about how many LGBTQ+ people are out of the closet?

Happy Pride Month!

I am wondering if the collective can help me locate data about how many people in the LGBTQ+ population are out of the closet. I’m curious, because I see many faceless profiles when I go on gay dating apps. Faceless profiles usually belong to persons who identify as down-low or in the closet.

I am further curious if a person’s location correlates to their out or in the closet status. Are some areas more open or closed?
