World Religion Map 2018: A Global Snapshot
The year 2018 marked a significant point in time for the global religious landscape, with Christianity and Islam remaining the two largest religions worldwide. The Pew Research Center's comprehensive study, released in 2015 but with data projections up to 2050, provides valuable insights into the distribution and growth of various faiths across the globe. Let's delve into the fascinating world religion map of 2018.
Christianity: The Largest Religion in 2018
In 2018, Christianity was the world's largest religion, with over 2.3 billion followers. This accounted for approximately 31.2% of the global population. The Pew Research Center projects that by 2050, Christianity will still be the largest religion, but its share of the world's population will decline to 30.7%. This shift is primarily due to higher fertility rates among Muslims and the aging population of Christians in Europe and North America.
Catholicism and Protestantism: The Two Main Branches
Christianity is divided into several denominations, with Catholicism and Protestantism being the two largest branches. In 2018, there were an estimated 1.3 billion Catholics, making up 17.7% of the world's population. Protestantism, including Pentecostalism, had around 800 million followers, comprising 10.8% of the global population.
Islam: The Fastest-Growing Religion in 2018
Islam was the world's fastest-growing religion in 2018, with over 1.8 billion followers, or 24.1% of the global population. The Pew Research Center projects that Islam will grow faster than any other religion in the coming decades, primarily due to high fertility rates and a significant number of Muslims being relatively young. By 2050, Muslims are expected to make up 30.1% of the world's population.
Sunni and Shia Islam: The Two Main Denominations
Islam is divided into two main denominations: Sunni and Shia. In 2018, Sunnis made up approximately 87-90% of the world's Muslim population, while Shias constituted 10-13%. The majority of Muslims in the Middle East, North Africa, and Southeast Asia are Sunni, while Shias are predominantly found in the Middle East, North Africa, and South Asia.
Other Major Religions in 2018

Buddhism had around 520 million followers, or 7.1% of the world's population. Folk religions, which include Chinese folk religions, African traditional religions, and Native American religions, had approximately 430 million followers, or 5.9% of the global population.
