One of the last sane

Anyone got any data on drop-out rates for different religious denominations?
I was talking the other day to a woman who was raised a Seventh Day Adventist. She dropped out of the church as soon as she left home and was of the opinion that drop-out rates are very high for some of the whackier denominations. Anyone know the truth of this?

I don't know, but if you're starting a study, you can add one dropped out Catholic.
