Christians are leaving the faith in droves and the trend isn't slowing down

If the current trends continue beyond 2050 then by the year 2070 the world’s population of Muslims would roughly equal that of Christians.

AN EXTENSIVE STUDY carried out by the Pew Research Centre has yielded some fascinating information regarding the trajectory of world religions over the next four decades.

As of 2010, Christianity was the dominant world religion with roughly 2.2 billion adherents and Muslims were second with about 1.6 billion adherents.

If current demographic trends continue however, Islam is expected to catch up to Christianity midway through the 21st century.

Furthermore, people are leaving Christianity in droves. About 106 million Christians are expected to switch affiliation from 2010 to 2050 while only about 40 million people are expected to enter Christianity.

The religiously unaffiliated (atheists, agnostics) are expected to see the largest net gains from switching, adding more than 61 million followers.

In North America, the fastest growing religious groups are Muslims and followers of “other religions” (an umbrella category that includes Baha’is, Jains, Sikhs, Taoists and many smaller faiths). Christianity is expected to decline from 78% of the overall population in 2010 to 66 percent in 2050.

Unaffiliated religions are expected to rise over that same time from 16% of the population to 26 percent. By 2050, the United States will have more Muslims (2.1% of the population) than Jews (1.4%).

In South America and the Caribbean, Christianity will see a slight dip over the next four decades, from 90% in 2010 to 89% in 2050. Over that same time the religiously unaffiliated population will add 45 million followers increasing from 8% of the population in 2010 to 9% in 2050.

If the current trends continue beyond 2050 – which is a big if considering unforeseen events that can happen over a 40 year span (such as war, famine, innovation) – then by the year 2070 the world’s population of Muslims would roughly equal that of Christians.

PastedImage-80131

Here are other chief findings from the report:

  • Islam will grow faster than any other religion over the next 40 years.
  • The number of Muslims will equal the number of Christians around the world by 2050. 
  • Atheists, agnostics and other people who do not affiliate with any religion – though increasing in countries such as the United States and France – will make up a declining share of the world’s total population.
  • The global Buddhist population will be about the same size it was in 2010, while the Hindu and Jewish populations will be larger than they are today.
  • In Europe, Muslims will make up 10% of the overall population.
  • India will retain a Hindu majority but also will have the largest Muslim population of any country in the world, surpassing Indonesia.
  • In the United States, Christians will decline from more than three-quarters of the population in 2010 to two-thirds in 2050, and Judaism will no longer be the largest non-Christian religion. Muslims will be more numerous in the U.S. than people who identify as Jewish on the basis of religion.
  • Four out of every 10 Christians in the world will live in sub-Saharan Africa.

    Sean, Ireland didn’t even have a 90% Catholic rate in the last census so not sure how you are coming up with that number.

    The next census will likely show it in the 70% area,

    Of course you are right, a large percentage of the Irish population in Ireland still consider themselves Catholic even though they don’t believe in many of the Catholic churches main teachings for example, Mary being a Virgin, that when you take communion you are actually eating Jesus and most certainly do not agree with the church’s frankly outdated and backward views on sex before marriage, condom use and other issues like divorce and marriage equality.

    What’s even more strange is back in around 2010 the Catholic Bishops commissioned a survey in relation to the people that do actually go to mass. They found that approx 10% of mass going Catholics don’t even believe in a God.

    It seems some people are so desperate to fit in with the community or keep their partners, husbands/wife’s, parents or grandparents happy that they’ll do the mass stuff even when they don’t believe in the all power got that the Catholic Church bases it’s entire believe structure on.

    Sean could not agree more I’m a firm believer that the school system is the last hold they have on Irish society. The census will only give you figures on the question asked. I’d like them to ask did you Christian your child to guarantee a place in your local government school. And if you are a Catholics are you a practicing Catholic. Because the figures don’t match reality.

    Surveys since the last census have shown that the majority of catholics are actually protestants. They don’t even believe in transubstantiation.

    Some are not even christians. They don’t believe in heaven and hell.

    And something like 8% are not even theists, they don’t believe in god.

    A lot of people identify as catholic as a cultural in-group identification and nothing to do with the religion.

    “It was around 84% last time.”

    And it had dropped from about 91-2% from memory, but that didn’t stop the newspapers reporting instead that the number of catholics had increased, which was technically true but the population increased in size, but grossly misleading.

    Actually the economist did an interesting piece about the perceptions of the number of Muslims vs. the actual population in different european countries. The media driven perception of Europe being ‘over run with Muslims’ has lead people to believing the numbers are at least 2-3 times the actual.

    The French think their country is 30% Islamic when it’s actually 8%

    The British think theirs is 21% when it’s actually 5%…

    The Catholic Church keep declining as they refuse to move forward at the same rate as the world. They like other religious groups want to preach an ideal life while they continue to live a lie. Even with the referendum coming up they won’t accept homosexual people for marriage. We live in the twenty first centaury why won’t they. It’s ok for them to be tweeting from Rome and using computers to keep us updated with first century blabber. They hit the self destruct button fifty or so years ago and it’s too late to stop it. Sure they will manage to manipulate the poor in Africa, Asia and south America but first world countries in most have seen the light.

    The headline is very misleading. The number of Christians continue to grow. Still the same percentage, and increasing later.
    But Europe continues to trade it’s inheritance for a pigs ear. The reality is that Europe is in such a mess with ideologies, it will shortly be ripe for conversion, the only question is will it flee back to Christianity, or will it be overrun by Muslims.
    Historically, when Christianity is been abandoned, God raises up Saints with the gifts necessary for reconversion.
