Understanding the religious composition of the world can be challenging due to its vast diversity. However, a simplified model can provide a clear perspective on the relative size of different religious groups globally. Imagine a world with only 100 people—this model, based on data from the Pew Research Center, allows us to visualize the distribution of major religions in a more accessible way.

• At the top of the list, 32 people would identify as Christians, making Christianity the largest religious group globally. The religion, with its diverse denominations, has a significant presence in regions across Europe, the Americas, and sub-Saharan Africa.
• 25 people would practice Islam, showcasing its prominence worldwide. Islam ranks as the second-largest religion, with major populations in the Middle East, Southeast Asia, and parts of Africa and South Asia.
• 15 people would be Hindus, with the vast majority concentrated in South Asia, particularly India, Nepal, and parts of Southeast Asia.
• In this simplified world, 14 people would be unaffiliated with any religion, a group that includes atheists, agnostics, and those who identify as secular or non-religious.
• With 7 people, Buddhism is another major world religion, although its global numbers are smaller compared to the others. Buddhism is primarily practiced in East Asia, Southeast Asia, and parts of South Asia.
• 5 people would follow folk religions, which include a wide variety of traditional beliefs often specific to particular cultures or regions. These beliefs often involve animism, ancestor worship, and local deities, and are especially prevalent in Africa, Asia, and Indigenous cultures around the world.
• In this model, 1 person would practice Judaism, the oldest of the Abrahamic faiths, with a global presence that remains significant, particularly in Israel and among Jewish communities worldwide. Additionally, 1 person would belong to other smaller religions, such as Sikhism, Bahá'í, Jainism, and Zoroastrianism.
