Below is the intro, and I just want to give a teaser as you should read this article:
“College-aged millennials today are far more likely than the general population to be religiously unaffiliated. This is true when they are compared to previous generations as well.
In fact, the Pew Research Center documents that millennials are the least outwardly religious American generation, where ‘one in four are unaffiliated with any religion, far more than the share of older adults when they were ages 18 to 29.'”
