Gospel Billboards in the United States

If you’ve ever taken a road trip in California, you’ve probably noticed the provocative evangelist billboards and posters that line the state’s major highways. Their emphatic slogans — “After you die, you will meet God” — and the 855-FOR-TRUTH toll free number are part of the familiar landscape of our interstate system.

The group behind the signs, a religious nonprofit called Christian Aid Ministries (CAM), recently launched ‘blitz’ messaging campaigns in two of California’s most populous cities — San Francisco and Los Angeles. According to the Amish-Mennonite non-profit’s annual financial report, it spent over $3 million on “billboard evangelism” in 2015 — up 400 percent since 2010.

Messaging strategy?

So, how does CAM decide where it puts up its billboards? One local news report suggested that the non-profit targets places where people seem to be “walking away from God and truth.” But, the numbers suggest otherwise.

Data collected from Google Maps shows at least 17 unique billboard messages. According to a CAM representative, the non-profit uses different gospel messages to target two specific audiences — non-Christians and Christians who they believe have strayed from the bible. So, I split these messages into two categories:

Messages aimed at encouraging Christians
Messages aimed at non-Christians


The waffle charts show that over 75 percent of the billboards are located in the nation’s top 100 most “bible-minded” market areas — shown in shades of red on the map above. The rankings are based on a survey conducted by the American Bible Society that ranks TV Nielsen designated marketing areas by “bible-mindedness.” According to a CAM representative, the non-profit uses the data from the American Bible Society’s study in determining its marketing strategy.

But, the messaging on the billboards doesn’t appear to change depending on the “bible-mindedness” of the location. Even the top 15 most “bible-minded” market areas have fairly even distributions of billboards with messaging that targets Christians and non-Christians.

Limitations of the data

You may have noticed that I only had messages available for about a quarter of the gospel billboards. That’s because CAM declined my request for a complete list of US billboards with their messages included. So, I had to get creative. I went through each billboard location and plugged its unique longitude and latitude coordingates into Google Maps. Then, I did this…
