Religion, regardless of losing popularity in the West, is spreading around the world. Thus, by 2050, Muslims will constitute 10 percent of the European population, while by 2100, there will be more Muslims than Christians in the whole world. In the future, all major religions will experience increase in the number of followers, except Buddhism.

By the year 2100, 35% of the world population will consist of Muslims, which will be 1% more than the Christians, wrote the authors of the Pew Research Center. Although many may not think so, PRC confirmed that the number of undecided religious people, which is meant to atheists, agnostics, and others who are not connected with religion, significantly decreases.

All religions, according to the PRC, will experience an increase in the number of followers, except Buddhism. The main reason for this is that Buddhists of today have very few offspring, and will grow old and die out.

A quarter of all Christians, more precisely 25.5% in 2010 lived in Europe. In 2050, there will be only 15.6% of Christians in Europe, while the majority will be in Africa.

It is expected that by 2050, the list of 10 countries with the highest Christian population is going to be drastically changed. While the United States and Brazil remain on top, Mexico will drop from third to sixth place, and Russia from fourth to eighth. Germany and China, on the other hand, could fall out of the list by 2050.

While it is common knowledge that Islam is growing globally, despite this increase, population of Muslims will constitute more than 50% of population only in two countries (out of 51) by 2050. The PRC report predicts that by 2050, 30% of entire world's population (2.8 billion) will declare themselves as Muslims, as opposed to 31% (2.9 billion) of Christians. It is likely that, by 2050, Europe will be home to 10% of all the world's Muslims, while Islam will be the second-largest religion in the US. It is assumed that the number of Muslims will grow, as there are more and more young believers, and infantile mortality is declining. At the same time, Muslims had the highest birth rate in the world between 2010 and 2015, and are currently making almost a quarter of the world's population (23.2%).

Jews will constitute 2%, and most of them will live in Israel. However, It should be noted that the current eight out of ten Jews live in the United States or Israel.

In 2010, 16% of the population identified themselves as religiously indifferent, and by all accounts, this number will drop to 13% in 2050. Countries with most non-believers were China, Japan and the United States, but in 35 years, most of them will be in the west.

At the end, the authors noted that their analysis is based on current trends and figures, but warned that any of these events - "scientific discoveries, armed conflicts, social movements, natural disasters and major changes in economic conditions" - could alter their predictions.
