Bill Maher Spells It Out

Atheists make up 3.1% - The 2015 Pew Religious Landscape survey reported that as of 2014 , 22.8% of the American population is religiously unaffiliated, atheists made up 3.1% and agnostics made up 4% of the US population.

Religiously unaffilated means they're not subscribing to any of the larger religious believes. That can range from Wiccan over New Age to nothing at all or not giving a shit. In my country that number is at 59 percent. Fun fact, 63 percent are still members of the Catholic church, according to similar polls. In any case, it's a fifth of the American population not attending traditional services with all strings attached.
