2021: The share of believers in a number of countries around the world
2020: Reduction in the share of Christians in the world to 28.8%, growth in the share of Muslims - to 25.6%
The proportion of Christians in the global population fell by 1.8 percentage points to 28.8% between 2010 and 2020, while the proportion of Muslims increased by 1.8 percentage points to 25.6%. Such data are cited by the Pew Research Center in a report on the global religious landscape, published on June 16, 2025.
According to RBC, the center's specialists analyzed more than 2.7 thousand studies and surveys to identify changes in the religious structure of the population. Despite the decline in the proportion, Christianity retains the status of the most common religion in the world. The total number of Christians over the decade increased by 121.6 million people to 2.3 billion.
The number of Muslims increased by 346.8 million to 2 billion, which exceeds the increase in all other faiths combined. Islam showed the highest growth rate among world religions during the studied period. Pew Research Center experts note that this trend is associated with demographic factors.
Buddhism became the only major religion to lose followers. The number of Buddhists decreased by 18.6 million to 324 million, and the share of this religion in the world structure decreased by 0.8 percentage points to 4.1%. The number of adherents of other faiths, including Hinduism and Judaism, changed in accordance with the overall population growth rate.
Significant growth was shown by a group of non-religious people. Their share increased by almost 1% to 24.2%, making this category the third largest after Christians and Muslims. The total number of people who do not practice religion increased by 270 million to 1.9 billion people.
Researchers call the rise in nonreligious people "astounding," given their demographic characteristics. This group more often includes older people with low birth rates. Experts attribute the increase in the non-religious population to the tendency to move away from religion among previously believers, especially Christians.[1]
Fetishism and totemism
The term "fetishism" acquires its scientific meaning only if it is understood to mean the veneration of fetishes, that is, material objects, things, sensually perceived objects taken from nature or artificially made, to which superstitious fantasy ascribes supernatural powers and abilities.
Totemism joins fetishism. It is also one of the oldest forms of religion. The central idea of totemism is the idea of collective ancestors and group kinship of people with animals - totems that form the world of mythical first-class social groups (genera), totemic first-class dual (half-animal-half-human) nature.
The most striking manifestations of totemism these days TAdviser observed in South Sudan among the people of Jie.
