Claims to be the fastest growing religion
Encyclopedia
Most increase in the population of any religious denomination is simply due to births. Still, the world's largest religions that are showing increases that outrun birth-rate include Christianity, Islam, and Hinduism.

There is often little coverage of the "No religious denomination" category (which includes deists, agnostics, atheists, and theists) although some evidence suggests they are growing rapidly. In the United States

the so-called "Nones" are the fastest growing religious status; Australia, Canada and much of Europe have also seen dramatic increases in the numbers of non-religious people.

Different definitions of "fastest growing"

Religions can grow in numbers because of conversion
Religious conversion
Religious conversion is the adoption of a new religion that differs from the convert's previous religion. Changing from one denomination to another within the same religion is usually described as reaffiliation rather than conversion.People convert to a different religion for various reasons,...

 or because of higher birth rates in a religious group (assuming that children take on the religion of their parents). Religions in particular countries can grow because of immigration.
The fastest growing religion could refer to:
  • The religion whose absolute number of adherents is growing the fastest (by whatever means).
  • The religion that is growing fastest in terms of percentage growth per year (by whatever means).
  • The religion that is gaining the greatest number of converts

    .
  • The religion that is gaining the greatest number of associative members (those associating themselves via survey, effectively a popularity vote)

Measures counting absolute numbers tend to favour the larger religions; measures counting percentage growth the smaller ones. For example, if a religion had only 10 followers, a single addition would be a 10% increase, and would therefore dwarf the percentage growth rates of the larger religions.

The difficulty of gathering data

Statistics on religious adherence are difficult to gather and often contradictory; statistics for the change of religious adherence are even more so, requiring multiple surveys separated by many years using the same data gathering rules. This has only been achieved in rare cases, and then only for a particular country, such as the American Religious Identification Survey in the USA, or census data from Australia (which has included a voluntary religious question since 1911). Worldwide data are more difficult to gather than data on a particular country.

, sometimes amplified by governments and policies at social institutions like universities or the reporting of commitments where the individual does not persist. This means that a lot of the data on growth of religions is derived from birth and immigration rates.

There are a large number of people who self-identify themselves as associated to a specific religion, but who are not religiously active. If, for example, asked to choose between Christianity and other religions they would say they were Christians; if asked to choose between Christianity, other religions and "Not religious", they would say "Not religious". This may make categorization difficult.

 fallacy to claim that being the "fastest growing religion" has any logical consequences about the truth of that religion.

While it is possible to find claims that almost any religion is the fastest growing, it is much harder to find ones backed up by scientific data. A selection of the more credible claims are given below, but even these are often contradictory, and most of them only cover a limited period time or a single region of the world.

Buddhism

Lewis M. Hopfe in his "Religions of the World" suggested that "Buddhism is perhaps on the verge of another great missionary outreach".(1987:170)

Buddhism is being recognized as the fastest growing religion in Western societies both in terms of new converts and more so in terms of friends of Buddhism, who seek to study and practice various aspects of Buddhism. As in the United States, Buddhism is ranked among the fastest growing religions in many Western European countries.

Buddhism is the fastest-growing religion in England's jails, with the number of followers rising eightfold over the past decade.

According to a recent report in the Journal for the Scientific Study of Religion, the Japanese Buddhist sect Nichiren Shoshu of America (NSA) is the fastest growing religion in the United States. Since coming to America in 1960 NSA has launched an aggressive proselytizing program. In 1967 it built a national headquarters and World Culture Center in Santa Monica, California, and has since established offices in most major U.S. cities. According to NSA’s figures the sect, which is part of the Japan based umbrella organization Soka Gakkai (Value Creation Society), now claims a half million members in the U.S. - up 100,000 from a year ago.

The records of The Church of Jesus Christ of Latter-day Saints show membership growth every decade since its beginning in the 1830s. Following initial growth rates that averaged 10% to 25% per year in the 1830s through 1850s, it grew at about 4% per year through the last four decades of the 19th century.

However, the percentage of Hindus in the population of India has decreased by 3 percentage points since 1961, dropping from 83.5% in 1961 to 80.5% in 2001 In addition to 80.5% of the population,that identify themselves as Hindus, there are approximately 40 million people (3%)that practice Jainism and Buddhism which evolved from Hinduism.

In a 2009 Newsweek article entitled, "We Are All Hindus Now," Lisa Miller notes that although the vast majority of Americans continue to identify with Christianity, at the same time we "are slowly becoming more like Hindus and less like traditional Christians in the ways we think about God, our selves, each other, and eternity." These are pivotal issues, and more and more westerners are coming to view the Hindu understanding of them as both rational and appealing. This does not mean there will be a large number of western converts to Hinduism anytime soon, but it does show the significant effect that Hindu thinking is having on the west. The growing Indian Hindu community in America is also helping to bring about a more realistic view of the tradition. In reincarnation, central to Hinduism, selves come back to earth again and again in different bodies. The article also pointed out that this is another way in which Americans are becoming more Hindu: 24 percent of Americans say they believe in reincarnation, according to a 2008 Harris poll.

Measures counting absolute numbers tend to favour the larger religions; measures counting percentage growth the smaller ones. For example, if a religion had only 10 followers, a single addition would be a 10% increase, and would therefore dwarf the percentage growth rates of the larger religions.

The difficulty of gathering data

Statistics on religious adherence are difficult to gather and often contradictory; statistics for the change of religious adherence are even more so, requiring multiple surveys separated by many years using the same data gathering rules. This has only been achieved in rare cases, and then only for a particular country, such as the American Religious Identification Survey in the USA, or census data from Australia (which has included a voluntary religious question since 1911). Worldwide data are more difficult to gather than data on a particular country.

, sometimes amplified by governments and policies at social institutions like universities or the reporting of commitments where the individual does not persist. This means that a lot of the data on growth of religions is derived from birth and immigration rates.

There are a large number of people who self-identify themselves as associated to a specific religion, but who are not religiously active. If, for example, asked to choose between Christianity and other religions they would say they were Christians; if asked to choose between Christianity, other religions and "Not religious", they would say "Not religious". This may make categorization difficult.

Claims to be the fastest growing religion

Note that it would be an argumentum ad populum
Argumentum ad populum
In logic, an argumentum ad populum is a fallacious argument that concludes a proposition to be true because many or most people believe it; which alleges: "If many believe so, it is so."...

 fallacy to claim that being the "fastest growing religion" has any logical consequences about the truth of that religion.

While it is possible to find claims that almost any religion is the fastest growing, it is much harder to find ones backed up by scientific data. A selection of the more credible claims are given below, but even these are often contradictory, and most of them only cover a limited period time or a single region of the world.
Buddhism
Lewis M. Hopfe in his "Religions of the World" suggested that "Buddhism is perhaps on the verge of another great missionary outreach".(1987:170)

Buddhism is being recognized as the fastest growing religion in Western societies both in terms of new converts and more so in terms of friends of Buddhism, who seek to study and practice various aspects of Buddhism. As in the United States, Buddhism is ranked among the fastest growing religions in many Western European countries.

Buddhism is the fastest-growing religion in England's jails, with the number of followers rising eightfold over the past decade.

According to a recent report in the Journal for the Scientific Study of Religion, the Japanese Buddhist sect Nichiren Shoshu of America (NSA) is the fastest growing religion in the United States. Since coming to America in 1960 NSA has launched an aggressive proselytizing program. In 1967 it built a national headquarters and World Culture Center in Santa Monica, California, and has since established offices in most major U.S. cities. According to NSA’s figures the sect, which is part of the Japan based umbrella organization Soka Gakkai (Value Creation Society), now claims a half million members in the U.S. - up 100,000 from a year ago.

. These religions have shared paralleled beliefs and have existed side by side for thousands of years.

In a 2009 Newsweek article entitled, "We Are All Hindus Now," Lisa Miller notes that although the vast majority of Americans continue to identify with Christianity, at the same time we "are slowly becoming more like Hindus and less like traditional Christians in the ways we think about God, our selves, each other, and eternity." These are pivotal issues, and more and more westerners are coming to view the Hindu understanding of them as both rational and appealing. This does not mean there will be a large number of western converts to Hinduism anytime soon, but it does show the significant effect that Hindu thinking is having on the west. The growing Indian Hindu community in America is also helping to bring about a more realistic view of the tradition. In reincarnation, central to Hinduism, selves come back to earth again and again in different bodies. The article also pointed out that this is another way in which Americans are becoming more Hindu: 24 percent of Americans say they believe in reincarnation, according to a 2008 Harris poll.

: A report from an American think-tank has estimated 1.57 billion Muslims populate the world - with 60% in Asia. The report was done by the Pew Forum Research Centre. The forum also projected that in 2010 out of the total number of Muslims in the world 62.1% will live in Asia.

However the report also included a statement saying While the global Muslim population is expected to grow at a faster rate than the non-Muslim population, the Muslim population nevertheless is expected to grow at a slower pace in the next two decades than it did in the previous two decades. From 1990 to 2010, the global Muslim population increased at an average annual rate of 2.2%, compared with the projected rate of 1.5% for the period from 2010 to 2030. The report also made reference to the fact that Muslims are estimated to make up 23.4% of the total global population in 2010 (out of a total of 6.9 billion people) and that by 2030 Muslims will represent about 26.4% of the global population (out of a total of 8.9 billion people).
