Study by Stanford Graduate School of Business on the influence of polling locations on voting behavior.

Shows that one-in-four adults under age 30 are an atheist, agnostic or religiously unaffiliated.

19% of Asian Americans are nonreligious.

Not only are one-in-five Americans nonreligious, younger Americans are the least religious population in the country. One in three Americans aged 18-29 are not religious. 

About half (53%) of Americans said they would be less likely to support an atheist as a presidential candidate.
