This would reflect a compound annual growth rate (CAGR) of 6.4%. This market includes the revenue generated by entities primarily engaged in running religious institutions. The rise in disposable income is a key factor influencing the market for religious organizations. Economic advancements and improved financial conditions lead to people engaging actively and making contributions to charitable events within their religious communities. As per the World Economic Forum (WEF), faith-related or inspired businesses contribute an annual sum of $437 billion to the US economy. When incorporating a broader spectrum of religious contributions, the WEF estimates that the US gains $1.2 trillion in socio-economic value each year.

Religious Influences in Corporations

The United States has the highest number of Christians, with 70% of its population adhering to Christianity. Many prominent brands in the country have a strong affiliation with religion, particularly Christianity. One example is Tyson Foods, Inc. (NYSE:TSN), a multinational corporation headquartered in Springdale, Arkansas, specializing in the food processing industry. As the world’s second-largest processor and distributor of chicken, beef, and pork, Tyson Foods, Inc. (NYSE:TSN) is deeply rooted in religious principles. Founder John Tyson openly discusses his Christian faith, and the company’s core values emphasize the commitment to “strive to honor God.” Since the year 2000, approximately 120 office priests have been employed by the company to provide compassionate pastoral care to its employees.

Interstate Batteries, a major distribution industry player headquartered in Dallas, Texas, is another example. The company clearly expresses its religious identity in its mission statement, aiming to “glorify God” by offering customers high-quality, value-priced batteries, related electrical power-source products, and distribution services. Former Company President Norm Miller received recognition from Dallas Baptist University for his Christian leadership at Interstate Batteries and in the community. Another popular company with a notable connection to religion is Chick-fil-A. The company, headquartered in College Park, Georgia, operates over 3,000 restaurants across the United States and Canada. It is the 3rd largest food chain in the US. Chick-fil-A is widely known for its strong Christian beliefs, influenced by its founder, Truett Cathy. Chick-fil-A also honors Christian values by offering fish-based sandwiches during Lent, catering to those who observe Friday fasts and abstain from meat consumption during that season.

Public companies like Marriott International, Inc. (NASDAQ:MAR) and Alaska Air Group, Inc. (NYSE:ALK) have also been known to have strong religious influences. Alaska Air Group, Inc. (NYSE:ALK) was previously known for sharing prayer cards containing Bible passages with all passengers onboard. However, the airline decided to suspend this practice to honor and respect the diverse religious beliefs held by its customers.

Here’s what Diamond Hill Capital said about Alaska Air Group, Inc. (NYSE:ALK) in its Q3 2023 investor letter:

“Other bottom contributors included our long positions in Alaska Air Group, Inc. (NYSE:ALK), Target Corporation and Johnson Controls International (JCI). Shares of regional airline Alaska Air Group and general merchandise retailer Target declined during the quarter amid a weakening consumer and (in Alaska’s case) airline pricing environment.”

With this context in mind, let’s take a look at our list of Christian countries in the world.
