- White Christians now account for fewer than half of the public. Today, only 43% of Americans identify as white and Christian, and only 30% as white and Protestant. In 1976, roughly eight in ten (81%) Americans identified as white and identified with a Christian denomination, and a majority (55%) were white Protestants.
- White evangelical Protestants are in decline—along with white mainline Protestants and white Catholics. White evangelical Protestants were once thought to be bucking a longer trend, but over the past decade their numbers have dropped substantially. Fewer than one in five (17%) Americans are white evangelical Protestant, but they accounted for nearly one-quarter (23%) in 2006. Over the same period, white Catholics dropped five percentage points from 16% to 11%, as have white mainline Protestants, from 18% to 13%.
- Atheists and agnostics account for a minority of all religiously unaffiliated. Most are secular. Atheists and agnostics account for only about one-quarter (27%) of all religiously unaffiliated Americans. Nearly six in ten (58%) religiously unaffiliated Americans identify as secular, someone who is not religious; 16% of religiously unaffiliated Americans nonetheless report that they identify as a “religious person.”
- There are 20 states in which no religious group comprises a greater share of residents than the religiously unaffiliated. These states tend to be more concentrated in the Western U.S., although they include a couple of New England states, as well. More than four in ten (41%) residents of Vermont and approximately one-third of Americans in Oregon (36%), Washington (35%), Hawaii (34%), Colorado (33%), and New Hampshire (33%) are religiously unaffiliated.
- Nearly half of LGBT Americans are religiously unaffiliated. Nearly half (46%) of Americans who identify as lesbian, gay, bisexual, or transgender (LGBT) are religiously unaffiliated. This is roughly twice the number of Americans overall (24%) who are religiously unaffiliated.
