It seems to me that Catholicism is more of a family thing than a personal faith thing. Many people who identify themselves as Catholics seem to be Catholics, because their families have been Catholic for generations, and these Catholic families marry other Catholic families, however nominal/lapsed/non-observant they are. Catholic evangelistic efforts, like the ones at my alma mater (a public university), seem to be geared towards lapsed/nominal/non-observant Catholics. There may be Catholic converts, but as far as I know, these converts typically have Christian backgrounds or are adherents to one of the Abrahamic religions.
Anyway, how many people actually convert to Catholicism nowadays, willingly, as fully consenting adults without Catholic, or even Christian, or even Abrahamic ancestry? Out of the Abrahamic religions, those peoples are known as pagans. So, I am asking how many people nowadays convert to Catholicism from generations-old paganisms?
I speak as an one-and-a-half-generation American with Chinese ancestry on both sides of the family. No Christian background for me, my parents, or my grandparents, but at least I know for certain that my grandparents were nonreligious atheists. Beyond my grandparents, I am not entirely sure what religious faiths they were. My father’s side of the family is from the rural countryside, so it is likely that they may practice traditional Chinese religion, but that’s mostly conjectural.
