The U.S. States That Believe in God the Least

Religion plays a significant role in many parts of the U.S., although not everywhere. In some states, more and more people are saying, “There is no God,” and are choosing not to follow any religion at all. This article ranks the states with the highest number of atheists based on the “unaffiliated” category, based on publicly available data—those who don’t belong to any faith. From states with just a few nonbelievers to places where religion is fading fast, we go from lowest to highest.

You’re probably going to be surprised by which states top the list, especially the one that ranks #1. Let’s get right into it.
