For example, in Mexico, a largely Catholic country, colonized by Catholic Spain, only 2-3% of Mexicans do not believe in God (from a 2004 BBC survey) yet in Spain today, 24% of Spaniards consider themselves “atheist” of “agnostic.” It is also not surprising either that you are likely to find more (serious) believers and churchgoers amongst black people in the U.S than white people in the U.S relative to their individual populations.

Food for thought.
