44% of Americans change their church

The Pew Forum on Religion and Public Life published this amazing figure. Could it be that this figure reflects a large number of interdenominational marriages? The married couple will attend the same church, which implies that either husband adopts wife's church, or vice versa. No way are husband and wife going to attend different churches, especially not after the first child. Since the couple was compatible enough to marry, it's fair to assume that their religious backgrounds are not too dissimilar.
