There is a widely held assumption in Western society called the ‘secularization hypothesis,’ which basically supposes that as the world becomes more educated and more scientific, religious belief will decline. This did happen in Western Europe in the nineteenth and twentieth centuries, and to a lesser degree in North America.
However, current trends are leading sociologists to predict that the world will become increasingly religious in the decades to come.
By 2060, Christianity and Islam are both projected to grow worldwide. Hinduism is expected to make a slight decline, and Buddhism is projected to decline by about 30 percent. Judaism is expected to hold steady at 0.2% of the world population.
Whereas the growth of Islam is mostly the result of birth rates in Muslim communities, Christianity far out-paces Islam when it comes to growth through conversion. In fact, the Christian population of China is growing so fast (mostly by conversion) that experts believe China could have more Christians that the United States by 2030, and that it could actually become a majority-Christian country by 2050.
Here’s what’s perhaps more surprising: by 2060, the percentage of the world population who identify as atheists, agnostics, or “none” is expected to decline from its current 16% down to 13% of the world’s population.
Secularization & Education
It turns out that the assumption that the more educated a person is, the more likely they are to become secular, is also pretty weak. Jews and Christians make up the majority of the most-educated people in the world. Christians also have the least amount of disparity when it comes to the education of women versus men.
While it is still common for nominally religious people in the United States to declare themselves non-religious if they are more educated, professing Christins with higher levels of education are just as religious as those with less schooling. In fact, highly educated Christians are more likely to attend church weekly than those Christians with less education.
The Likelihood of Becoming Religious vs. Becoming Non-religious
A recent study found that 40% of Americans raised non-religious become religious – typically Christian – as adults, whereas only 20% of those raised Protestant become non-religious. This means that secular families are twice as likely to raise children who become Christians as Christians families are to raise church who become non-religious.
Interestingly, it is “full-blooded” Christianity which is growing around the world, including in North America and Europe, and not a theologically liberal form.
What Do We Make of This?
Surely there is much work to be done, and projections do not guarantee that future outcome, but these numbers help us to see that there are many commonly-held assumptions about Christianity and society which are actually false. As Christians, we must keep our hand to the plow, endeavoring to preach the gospel, as we are called by Jesus to do.
