Is There a Difference Between Religiously Unaffiliated and Atheists?

Is it fair to say a less religious america means a less spiritual America? The religiously unaffiliated are people who don't practise some form of faith or spirituality. In fact, polling for myriative sources and in a bunch of studies that have been done yo, display that this group has often exhibited a lot of pray. Glad of them still go to church or synagogue or a mosque, but they sit in the back, and not necessarily want to ascribe to a specific tradition.
