Pew researches predict that when Latinos reach the 100 million mark in the US -- around 2050/55 -- only 40% will identify as Catholic (the rest will identify as either non-affiliated [24%], Evangelical Protestant [21%] or some other tradition). But surprisingly, nearly a quarter will identify as non-affiliated, non-Christian. We'll see.
