Curious about the basis here. Living in Canada which I guess comes in between US and the Scandinavian countries when it comes to religion and your daily life, I've never seen 'education' being a factor for people being atheist or even agnostic here.
With the exception of some countries, I feel that religion is prevalent just because that's the last bit of hope and structure people can hold on to. Whether it's false or not, it's still more reliable then corrupt politicians, coorporations that seek to exploit whatever resources available for it's own needs and just general shittyness of living in terrible conditions. I feel it's human nature to reach out to a deity when that's the only option you have. Seeing the conditions of how millions live in a poor country like Pakistan, religion (whatever they believe in) might be the only thing keeping these people from complete dispair.
