2015 Sees Sharp Rise in Post-Christian Population by Barna Group

http://cities.barna.org/america-more-post-christian-than-two-years-ago/

While the United States remains shaped by Christianity, the faith’s influence—particularly as a force in American politics and culture—is slowly waning. An increasing number of religiously unaffiliated, a steady drop in church attendance, the recent Supreme Court decision on same-sex marriage, and the growing tension over religious freedoms all point to a larger secularizing trend sweeping across the nation.

But how do the numbers stack up? Is America, home to the largest Christian population in the world, actually becoming a “post-Christian” nation? In a recent study, Barna Group analyzed 60,808 interviews conducted over a seven-year period to measure irreligion in American cities. Currently, 78% of Americans describe themselves as “Christian,” but in order to dig deeper than just self-affiliation, Barna Group looked at a variety of key faith indicators for both belief and practice.

To measure a person’s level of irreligion, Barna Group tracks 15 metrics related to faith (you can find the full list of 15 at the end of the article). These factors speak to the lack of Christian identity, belief and practice. These factors include whether individuals identify as atheist, have never made a commitment to Jesus, have not attended church in the last year, or have not read the Bible in the last week.

These kinds of questions—compared to ticking the “Christian” box in a census—get beyond how people loosely identify themselves (affiliation), and get to the core of what people actually believe and how they behave as a result of their belief (practice). These indicators give a much more accurate picture of belief in America.

To qualify as “post-Christian,” individuals had to meet 60% or more of the factors (nine or more out of 15 criteria). “Highly post-Christian” individuals meet 80% or more of the factors (12 or more of these 15 criteria). Read more about Barna’s post-Christian metric.

Where Are We as a Nation?

Whether one believes this decline of “Christian America” calls for a time of lament, or presents great opportunity (or both) for the church, one cannot help but accept the changing landscape. In just two years, the percentage of Americans who qualify as “post-Christian” rose by 7 percentage points, from 37% in 2013 to 44% in 2015. Across the United States, cities in every state are becoming more post-Christian—some at a faster rate than others

The Top 15 “Post-Christian” Cities

As was the case in 2013, the religiously unaffiliated and unchurched are concentrated in New England and the Northeast. Touted as the foundation and home-base of religion in America, and a region that often sets the political tone of the nation, New England dominates the post-Christian metrics, claiming five of the top 10 most post-Christian cities, including Boston, MA (65%), Providence, RI (60%), and Portland, ME (60%), with eight of the top 10 in the greater Northeast region.

The West coast is also fairly well represented among the top 15 cities, with San Francisco, CA (66%) climbing up the rankings from 6th place in 2013 to top the list as the most post-Christian city in America, and Los Angeles, CA (54%) coming in at 15th place. But other West coast cities like San Diego, CA (50%), and Portland, OR (51%) actually dropped out of the top 15 from 2013, either because of a decrease or minimal increase in post-Christian metrics compared to 2013. Other outgoing cities include Denver, CO (52%), and Cedar Rapids, IA (51%).

Newcomers to the top 15 cities include Las Vegas, NV (59%), Fort Myers-Naples, FL (56%), Chicago, IL (54%), and Los Angeles, CA (54%). These markets, and many others saw a higher than average increase, Las Vegas being a striking example, with an increase of 16 points over 2013. Boston, San Francisco, and Chicago all have similarly strong growth in their post-Christian populations, with increases of 12 to 13 percentage points in each city.

Post-Christianity by Region

The county’s largest cities are a mixed bag with northern cities like New York (59%), Chicago (54%) and Philadelphia (54%), all shooting up the rankings compared to their 2013 spots. But southern cities like Houston (40%), Phoenix (51%), San Antonio (35%), and Dallas (32%) all dropped an average of 10 spots in the post-Christian rankings compared to their 2013 position. In most cases, the percentage of post-Christian residents did not change much in those cities.

The South and Midwest have both lower comparative, and slower rates of post-Christian growth. This is inline with these regions’ typically higher rates of church attendance and self-identified Christians.

Cities like Birmingham, AL grew only slightly from a post-Christian population of 16% in 2013 to 18% in 2015. This is a similar story with cities across the South and Midwest like Nashville, TN (23%), Charlotte, NC (25%), Dallas/Ft Worth, TX (32%) and Columbus, OH (46%). These are all cities that have—and maintain—a much lower percentage of post-Christian individuals.
