The majority of South Koreans [46.1%] are non religious. Now, this doesn't mean that they're atheists, it just means that they don't really affiliate with a religion and are too busy to care about it. The largest religion in South Korea right now is Christianity at 29.1% [Protestantism 18.3% + Catholicism 10.9%], followed by Buddhism at 22.8%, and other religions that make up the remaining 1.7% of the population.

The list that you're about to see shows what religion a kpop idol affiliates to. Some of the idols from specific groups that I listed have question marks on them because they haven't stated their religion. If you do know by any chance, please feel free to comment! If I made any mistakes, please let me know and I'll fix the list!

**? = indicates that idol hasn't stated their religion

**() = indicates that idol may have a different religion from other sources

Again, please remember that there is a difference between being an atheist and being non religious. Atheism means that you don't believe in a god, while being non religious means that you don't actively practice a religion.
