If you are curious as to which states are the most/least religious, simply check out the Pew Forum’s Religious Landscape Survey. It’s all there. And then you can go ahead and check out how the various states are faring in terms of societal well-being. The correlation is clear and strong: the more secular tend to fare better than the more religious on a vast host of measures, including homicide and violent crime rates, poverty rates, obesity and diabetes rates, child abuse rates, educational attainment levels, income levels, unemployment rates, rates of sexually transmitted diseases and teen pregnancy, etc. You name it: on nearly every sociological measure of well-being, you’re most likely to find the more secular states with the lowest levels of faith in God and the lowest rates of church attendance faring the best and the most religious states with the highest levels of faith in God and rates of church attendance faring the worst.
