I do not live in any kind of religious vacuum nor in one religion. Nor do inquire as toothed nature or variety of their belief unless they are overt about it.
I spent the last 4 days camping with musicians, artists, and creatives...it never came up.
On the other hand I have a friend who started an interfaith comedy group, and it always comes up, lol.
Amongst my juggling and performer friends I would say about 10% wear their beliefs on their sleeves, as they are part of their show, either basically proselytizing or reinforcing beliefs and stories in their show as they are hired for religious functions.
I would say in general my friends group is probably fairly similar to the US average. (Although I have not looked at that)
I would guess most are non practicing Christianesque variety. The next largest group would be non believers (agnostics and don't care), then Christians, followed by Jews (they are probably the largest participants among my Comedian, juggler, magic, mime, performance groups) I would guess atheist follow them, but I think it would be interesting where atheist and agnostics fall.
Next I believe would be Muslim, like my Jewish and Christian friends I would put less than 10% as devout, and probably 30% as seriously practicing. The majority are social, they may follow the dietary requirements, and holidays, festivals, (Ramadan, and high holy days, large gathering type functions) but daily prayer, ritual, or mosque (church, synagague) attendance is occasional or for family function.
Pagans might be next if I lump druids, witches, and folks that believe in the earth powers of crystals and nomes and fairies, luck and leprechauns, Gaia... I see paganism as sort of the woke word of 400 years ago. Of you don't believe in my savior I will make up a derogatory name for your groups and lump them all together to demean the collective and make me feel better.
Hindus and Buddhists they would be next i know there are many and if i group them together prolly more than the pagans (i have lumped together), although most of them I know are not of eastern decent or upbringing, they just found the tenants or ohilosophy more in their line of thought than whatever
they were indoctriated, I mean raised in.
I would put outright atheists below that although I am probably wrong, I think most atheists have their moments where they pray or talk to some imaginary friend or cosmic HGTVforce to help them out of a car accident, health crisis, love issue or jail. Ain't nothing like a crisis to bring out a god!
Then we would have the Bahai, Rosicrucians, Quakers, Mormons, etc.
That last bunch some would be under the Christian category but they are also distinctly different somehow in my mind.
I would not know how to further categorize those of Christian beliefs in percentages, definitely mostly protestant over catholic, but as far as AME, methodist, Episcopalian Lutheran, Baptist...I have no clue.
