Between 2010 and 2020, the world's religious landscape changed considerably. Here are some statistics from the latest [report](https://www.pewresearch.org/religion/2025/06/09/how-the-global-religious-landscape-changed-from-2010-to-2020/?ref=theparnassian.com) by the Pew Research Center:

**Christianity remains the largest religion in the world**: over the decade the number of Christians grew by 122 million, reaching 2.3 billion by 2020\. **The growth in the number of Muslims, however, was almost three times as great**: 327 million new adherents. The total number of Muslims reached 2 billion. This is more than the growth of all other religious groups put together. Such growth is due, above all, to a high birth rate.

**Apart from Islam, only one group increased its share of the world's population: the religiously unaffiliated**, who identify with no religion at all. By 2020 their share had reached 24.2% of the Earth's population, making them the third largest group after Christians and Muslims.

**The greatest change in share of population over these ten years was experienced by Christianity itself**. If in 2010 the bulk of Christians (25.8%) lived in Europe, by 2020 the centre of Christianity had shifted to sub-Saharan Africa, which is now home to 30.7% of all the world's Christians. This is the result both of natural population growth in the region and of the mass abandonment of religion in Western Europe. By way of comparison: at the beginning of the twentieth century only 1% of the world's Christians lived in the countries of sub-Saharan Africa, while two thirds lived in Europe.
