Christianity is at the moment the world’s largest faith, making up a 3rd of the world’s inhabitants with 2.2 billion adherents. Pew analysis exhibits that Islam is the quickest rising faith on this planet. The Islam will make up 30 % of the world’s inhabitants by 2050, in comparison with simply 23 % of the inhabitants in 2010. Meaning the  Muslims on the planet will practically equal the number of Christians by 2050.If Islam’s progress spurt continues, Pew knowledge reveals, Muslims may outnumber Christians quickly after the year 2070.
That is to not say that the whole Christians are decreasing; Christianity’s growth rate is simply not as quick as Islam’s. Whereas the  Christians will enhance from about 2.1 billion to 2.9 billion by 2050, Muslims will bounce from 1.6 billion to 2.8 billion.
This progress has to do with the comparatively younger age of the Muslim inhabitants in addition to converts and excessive fertility rate. Other religious groups  are getting old populations. Amongst Buddhists, for instance, half of adherents are older than 30 and​ the typical beginning charge is 1.6 kids. In contrast, in 2010, a 3rd of the Muslim inhabitants was below 15. What’s more, each Muslim woman has an average of 3.1 children, while the average for Christian women is 2.7.
The Pew analysis revealed two different fascinating shifts in world religious views, Cooper man says.
Atheists, agnostics and those that don’t affiliate with faith will make up a smaller share of the world’s complete inhabitants by 2050 — regardless that the group is rising within the U.S. and Europe. The decline is primarily as a result of those that are unaffiliated religiously have low fertility charges, with ladies bearing a mean of 1.7 youngsters of their lifetime.
Between now and 2050, the hub of Christianity will even shift — from Europe to sub-Saharan Africa. As of 2010, the vast majority of the Christian inhabitants — 25.5 % — lived in Europe, however sub-Saharan Africa will turn into dwelling to just about 40 % of the world’s Christians by 2050. Fertility charges are additionally behind this modification. Christians residing in sub-Saharan African have the best fertility charges amongst Christians worldwide: Each woman has, on average, 4.4 children.​
Cooperman emphasizes that quite a bit might change between now and 2050.
“We’re not saying that this may occur; it is if present patterns and developments proceed,” Cooper man says. “We have no idea what is going on to occur sooner or later. There could possibly be battle, revolution, famine, illness. These are issues nobody can predict and that might change the numbers.”
