Countries with a main religion that is rare

Interesting but I'm not sure this is well evidenced. Here's what I saw from a quick Google:

Christianity is most common in South Sudan; with animism in second. If you want to include animism, most of the Indigenous Beliefs of Madagascar are based around animism

Dang, was halfway through typing Madag.....thingie.

any more countries that would be included if atheism wasn't on the list of common religions? feels wrong to include it as one of the main world ones

I thought the South Sudanese were mostly Christian, and that this was one of the reasons they wanted to break off from predominantly Muslim Sudan.
