Those who grow up in an atheist household are least likely to maintain their beliefs about religion as adults, according to a study by Georgetown University’s Center for Applied Research in the Apostolate (CARA).
Only about 30 percent of those who grow up in an atheist household remain atheists as adults. This “retention rate” was the lowest among the 20 separate categories in the study.
I honestly find these results very surprising, the entire article is available at the link above.
I honestly wonder how much of that is due to social pressure, such as joining a church because one’s partner is part of the church.
I went to church up until I was about 12 or so, then my mother decided to let me make my own choice, she did the same with both of my brothers as well.
One of us joined a christian church after getting engaged to a member of the church, my other brother is agnostic, and I’m a complete skeptical non-believer but didn’t come to that until my early 30’s (I was pantheistic and then agnostic before that).
Again, it would be interesting to see the reasons behind atheists deciding to join a religion.
