What is the fastest growing religion?

One answer

By all the reliable sources, Islam is the fastest growing religion in the world. It has been verified by many independent sources, many of which are listed below.

CNN World News ( 14 November 1997 Report --- See link below )

World Christian Database ( 200-2005 Survey --- See link Below )

Foreign Policy ( May 2007 Report --- See link Below )

And also, by many other websites like,

People's Daily Online ( 2 Nov, 2006 --- See link Below )

Islam is Growing ( --- See link Below )

And, the number of adherents of Protestants and Catholics is decreasing. So, as people are accepting Christianity, they are leaving it at a greater rate as reported in leading newspaper. The New York Times ( 25 Feb, 2008 Report --- See link Below )

Therefore, as verified by indepedant news media, western sources and even by the christian organisation itself, Islam is indeed the fastest growing religion in the world.

In short- By percentage growth: Unknown

By real person growth: Christianity

By percentage growth the fastest growing religions in the world are the smaller religions. This is because with a smaller sample size, every additional adherent accounts for a higher percentage increase.

Therefore, by percentage growth we are uncertain what the fastest growing religions in the world are. However, logically speaking with statistics in mind by percentage growth the larger religions including Christianity (2.2 Billion Adherents), Islam (1.3 Billion) and Hinduism (900 million) are the least likely to be the fastest by percentage growth. An example to illustrate this point is Deism in the United States of America. Although in the period of 1990-2000 it experienced a growth rate of 717% the amount of new followers was very small and the large percentage increase is attributed to a smaller sample size.

The alternative measure for fastest growing religion in the world is growth by the number of new adherents. That is, the religion to gain more new believers each period would be the fastest growing religion.

As it stands the fastest growing religion by this measure is Christianity. Using the most up to date figures we determine that on average in 2007 Christianity gained 7-8million more adherents than any other religion (i.e. Islam, followed by Hinduism at 17million less).

In conclusion, the fastest growing religion by percentage growth is unknown as smaller religions are not usually account for. By number of new adherents per period Christianity is the fastest growing religion.

A side note, any argument that a religion is true because it is the largest or fastest growing is a logical fallacy. The amount of adherents or growth rate does not imply validity.

According to the ARIS survey, "deity" at a growth rate of 717 is not the fastest growing. "Wiccan" (for example) had a growth rate of 1,550%. In America it was Wicca.

Another answer

By number of new adherents Christianity is the fastest growing religion in the world with 30,360,000 new adherents annually (from 2000-2005). This is followed by Islam with 23,000,000 new adherents annually and Hinduism at 13,000,000.

There are various contenders for the title of fastest-growing religion in percentage terms, generally quite small, evangelistic religions such as Falun Dafu, or Falun Gong.

The fastest growing religion in terms of absolute numbers is probably Islam, simply because of its size and the generally high birthrate of Muslims.
