Interestingly, religious families are above 2, but not quite to the 2.5 required to counteract people leaving the faith. Orthodox religious are above 2.5, so the future will be quite religious with ‘nones’ becoming more of a minority…
The future belongs to the Orthodox Jews and the Amish. It doesn’t take many generations of families with 8 kids to outbreed the agnostic populations on the coasts. It’s going to be wild, but none of us will likely be around to see it happen.
