Churched and unchurched adults are not evenly distributed across the country—attendance varies widely from city to city and region to region. Many cities outpace the overall U.S. population when it comes to church avoidance. Barna’s latest report ranks the nation’s largest cities by unchurched population. Barna’s latest report ranks the nation’s largest cities by unchurched population.

The U.S. has a reputation for being exceptionally religious—and it is true that, historically speaking, churchgoing has played an outsized role in American identity. Still, millions of Americans have little to no connection to local congregations.

Currently, about four in 10 U.S. adults qualify as “unchurched” under Barna’s definition (38%). Unchurched adults have not attended a church service, except for a holiday or special occasion, at any time within the past six months.

Churched and unchurched adults are not evenly distributed across the country. Church attendance varies widely from city to city and region to region. Many cities outpace the overall U.S. population when it comes to church avoidance.

For example, the San Francisco metro area tops the list of America’s most churchless cities: Six in 10 Bay Area residents meet the Barna definition of unchurched (61%). A full list of the nation’s largest metro media markets is shown below, ranked by unchurched population.

Barna tracks not only overall churchlessness, but also what proportion of unchurched adults are “dechurched”—that is, who used to attend regularly but have not attended at all in the past six months—and what proportion are “never churched”—meaning they have never in their lives regularly attended a church. Among the general U.S. population, 29% are considered dechurched and 9% are never churched, for a combined total of 38% unchurched. (For a deeper dive into the substantial differences between these two groups, read Churchless by George Barna and David Kinnaman.)

While San Francisco is number one overall when it comes to churchless residents, it ranks sixth on the never-churched list (14%), outpaced by:

1. West Palm Beach-Ft. Pierce, FL (17%)
2. Santa Barbara-Santa Maria-San Luis Obispo, CA (16%)
3. New York, NY (15%)
4. Harlingen-Weslaco-Brownsville-McAllen, TX (15%)
5. Chico-Redding, CA (15%)

However, the California Bay Area takes the top spot when it comes to dechurched adults (48%), ahead of:

1. Seattle-Tacoma, WA (44%)
2. Portland-Auburn, ME (43%)
3. Boston-Manchester, MA (42%)
4. Albany-Schenectady-Troy, NY (41%)
