While Christianity remained the largest global religion from 2010 to 2020, the latest Pew Research study found that followers of Islam outpaced every world religion in population over the course of the decade.
The recently released report, “How the Global Religious Landscape Changed from 2010 to 2020,” includes data from over 2,700 sources, including national census, demographic surveys, and population registers. Some of the estimates made in the report originate from data about 2020 that was not made available till 2024 due to the COVID-19 pandemic, which delayed census data in at least 65 countries.
The report covered 201 countries, focusing on seven religious categories: Christians, Muslims, Hindus, Buddhists, Jews, people who belong to other lesser-known religions, and religiously unaffiliated.
According to the report, the total number of Christians rose by 122 million from 2010 to 2020, while the total number of Muslims rose by 327 million — “more than all other religions combined.” The global Christian population rested at 2.3 billion in 2020, while the global Muslim population came to 2 billion.
