I know that
-Mormons are members of the largest Church ever to begin in the United States!
-They don't ingest drugs, including alcohol and caffeine
-They tend to be very family-oriented and frequently have larger than average (for the U.S. )families
-They are highly concentrated in the state of Utah but claim members all over the U.S. and the world, largely due to their focus on missionary effort.
Anecdotally, I used to think I had some sort of anti-Mormon-missionary scent I gave off or something, because I would see Mormon missionaries all over town and none of them ever approached me. I realize this is silly, but I felt sort of offended! I'm really fascinated by religion, so I always felt it would be fun and interesting and a great learning experience to talk to a missionary and learn more about their experience doing missionary work.
Well one day I was late to meet my partner for a ride and it was POURING rain and all of a sudden a Mormon missionary came out of nowhere! But because I was being picked up, was late, and was soaked, I didn't have time to talk. Chalk it up to bad luck, I guess, but at least now I know they aren't purposefully avoiding me. ;)
