This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 12th (it came out in 2015), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

Muslims Are Increasing in Number at a Faster Pace Than Other Religious Groups

Conrad Hackett at the Pew Research Center has headed up a group of researchers at Pew, aided by the researchers at the International Institute for Applied Systems Analysis (IIASA0 in Vienna and the Vienna Institute of Demography to produce a very eye-opening set of population projections broken out by religion. This analysis deserves a lot more attention than I can give to it in one blog post, so here I am just going to hit the highlights (more highlights at CNN) and then I will dig into more details in subsequent posts.

The projections suggest that by 2070 the number of Muslims in the world will catch up with Christians, if current trends continue. They also suggest that by 2050 Muslims could account for 10% of Europe's population and that 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."

Furthermore, four out of every 10 Christians in the world will live in sub-Saharan Africa, but this is also the region of the world with one of the highest rates of growth among Muslims and the growing friction and tension is felt in the recent shooting of Christian college students by Islamic extremists in Kenya.

Overall, the global numbers could shift a bit depending upon what happens in China:
For example, China’s 1.3 billion people (as of 2010) loom very large in global trends. At present, about 5% of China’s population is estimated to be Christian, and more than 50% is religiously unaffiliated. Because reliable figures on religious switching in China are not available, the projections do not contain any forecast for conversions in the world’s most populous country. But if Christianity expands in China in the decades to come – as some experts predict – then by 2050, the global numbers of Christians may be higher than projected, and the decline in the percentage of the world’s population that is religiously unaffiliated may be even sharper.
The key element here is especially the trend of the birth among Muslims, in particular, in various regions of the world--a topic that I have been following for a long time and which I referenced yesterday with respect to Iran.
