You said it, brother (sister?). In each country there are subcultures (religious fundamentalists, usually) that have birth rates well above replacement. Secular culture has managed to peel away many of their kids in recent decades but, with the kind of uninspiring, plasticky productions currently streaming out of Hollywood / big label music, that process is about to change. Let's just say, your radio is likely to play a lot more Christian rock in your old age.
