Most Populated Religion in The World Based on Statistics

According to the United States Census Bureau’s International Database, around 5 and a half percent of the world’s population defines themselves as Anglicans. That’s roughly 617 million of the earth’s 7,144 billion people in 2010. Anglicanism is not only one of the largest Christian churches in the world, it also has an exceptionally long history. How did this religion get started? Is it different from other forms of Christianity? What is its response to modern controversies such as climate change, gay marriage, and vaccine skepticism?

The world’s predominant religion is being debated and researched more and more often. Every global institution that sifts through statistics will begin to realize the consequences, influences, and causes that deal with religious factors. This is, most of the time, proving to be a controversial issue due to its political nature. The majority of the populations in countries all over the world participate in one religion or another. The statistics of religious membership are typically collected through censuses and large surveys. Most recent data has found that Islam is still the world’s largest religion by number of adherents.

  • Buddhism

Buddhism is a religion and philosophy encompassing a variety of traditions, beliefs and practices, largely based on teachings attributed to Siddhartha Gautama, commonly known as the Buddha. The religion originated in India sometime between 500 BC and 300 AD. Major branches of Buddhism are generally divided into less than two dozen sects, often defined by geography or tradition. In meditation practices, for example, Tibetan Buddhist monks tend toward “solidity” and Indian monks toward fluidity; Chinese Buddhists may focus on the breath while Japanese Buddhists use the mind’s eye as an object of meditation.[7][8]

Folk Religion

Folk religion is a general term that refers to the indigenous religious beliefs and practices of a people or culture. Folk religions are often closely associated with ethnic identity, as they are centered on the relationship between humans and the gods they believe in. In some cases, folk religions can be seen as a form of magic; however, this is not always true.

In 2021, it was found that there were roughly 5.1 billion people who practiced folk religion worldwide. This number grew to 6 billion by 2022, and 7 billion by 2023—the last year statistics were available for this data set at press time.

Final Thought

As you can see, the most populated religions in the world are Christianity and Islam. There are some interesting facts about these two religions and how they compare with each other. For example, Christianity is a monotheistic religion that teaches love for all people regardless of race or gender while Islam teaches that there should be no other gods beside God (Allah). Another important difference between them is their holy book: Christians believe that Jesus Christ was born from the virgin Mary while Muslims believe Muhammad was chosen by God to deliver His message through him as an angel visited him three times before revealing this message during his last one hour spent praying in Mecca before starting preaching all over Arabia after being commanded by Allah to do so as well (Sahih Bukhari).
