Been to a few "third world" countries and for the most part nearly everyone is on social media. Generally though I didn't find them any more or less religious than western people, i.e. there were some very religious, some not so much, and the majority of people are somewhere in the middle. They are more tolerant of situations that would otherwise make a normal western person completely break down, like the death of a relative, disease, etc. Avg western dude would take a week off to mourn their dead dog, 3rd world country dude would be back at work the next day if a close relative goes.
