I do appreciate their citations but the spin is a bit much. I’m still very skeptical about the interpretation of a “return to religiosity” rather than religious immigrants continuing their religious observances in their new home countries.

To show a proper “return to religious observance” (any religion, not just Christianity) means showing a large number of people who attend religious services regularly but whose parents do not.

I agree that immigration is probably playing a role, perhaps even a significant one, in these numbers, but at the same time this is also expected even without immigration. Religious families are having more children which means that, over time, there would be an inflection such that a generation starts becoming significantly more religious than the one prior - even if it's 100% because the children of that generation were born to religious families. Bringing over large numbers of religious immigrants is just speed running this endgame.

Yes perhaps I should not have focused on immigrants when the overall question I want to ask is if this effect is driven by religious subgroups/subcultures which include both immigrants from religious countries as well as people from religious communities within the US.

My hypothesis is that we’re not seeing much of a “return to religious observance” from children of parents with low/no religiosity and that nearly all of the resurgence is driven by the aforementioned religious subgroups.
