This latest graphic (HT Veith) shows some interesting data:

This study seems to show what other studies by Kara Powell  have determined – about a 50% retention rate for Protestants. The Apollos Project exists to change that reality.

The other interesting stat is that athiests are losing their children at a higher rate! It is a hard time to be an athiest.

I take any of these statistics with a grain of salt. Who is surveyed? What are their definitions? Without a careful controlled look at all those factors, it is hard to put a lot of stock in the studies.

Nevertheless it is interesting. And I would not want to be an atheist!
