Religiously unaffiliated people have been for some time. Pew Research Center’s massive makes clear just how quickly this is happening, and also shows that the trend is occurring within a variety of demographic groups – across genders, generations and racial and ethnic groups, to name a few.
Religious “nones” – a shorthand we use to refer to people who self-identify as atheists or agnostics, as well as those who say their religion is “nothing in particular” – now make up roughly 23% of the U.S. adult population. This is a stark increase from 2007, the last time a similar Pew Research study was conducted, when 16% of Americans were “nones.” (During this same time period, Christians have fallen from 78% to 71%.)
Overall, religiously unaffiliated people are more concentrated among young adults than other age groups – 35% of Millennials (those born 1981-1996) are “nones.” In addition, the unaffiliated as a whole are getting even younger. The median age of unaffiliated adults is now 36, down from 38 in 2007 and significantly younger than the overall median age of U.S. adults in 2014 (46).
