Jump to navigation Jump to search

Sources such as Encyclopædia Britannica or the World Christian Encyclopedia have listed Baháʼí membership as over 7 million.[1][dead link][2] More conservative estimates produced by the Baháʼí World News Service reports a Baháʼí membership of more than 5 million worldwide, in "virtually every country" and many territories.[3] As such, the Baháʼí Faith is recognized as the second-most geographically widespread religion after Christianity,[4][5] and the only religion to have grown faster than the population of the world in all major areas over the last century.[6]

Membership data on a relatively new, worldwide religion are difficult to arrive at. The religion is almost entirely contained in a single, organised community, but the Baháʼí population is spread out and not in a majority anywhere.[7] Populations are not assigned a Baháʼí religious adherence by birth, as is the case with other major religions such as Islam and Christianity.[7] Few religious surveys include the Baháʼí Faith due to the high sample size required to reduce the margin of error, and those that have included the Baháʼí Faith are known to underestimate or overinflate many proportionally small groups.[8] Additionally, Baháʼí membership data does not break out active participation from the total number of people who have expressed their belief.

The official estimate of "more than five million Baháʼís" in the world was originally arrived at in 1991 by the Baháʼí World Centre[9] and has not changed since.[3] The official agencies of the religion have focused on publishing more concrete data, such as numbers of local and national spiritual assemblies, countries and territories represented, languages and tribes represented, and publishing trusts.[10][3]

Definition of membership[edit]

In the 1930s the Baháʼís of the United States and Canada began requiring new adherents to sign a declaration of faith, stating their belief in Baháʼu'lláh, the Báb, and ʻAbdu'l-Bahá, and affirming a declaration that there are laws and institutions to obey. The original purpose of signing a declaration card was to allow followers to apply for lawful exemption from active military service.[11] The signature of a card later became optional in Canada, but in the US is still used for records and administrative requirements.[12] Many countries follow the pattern of the US and Canada.

Other than signing a card and being acknowledged by a Spiritual Assembly, there is no initiation or requirement of attendance to remain on the official roll sheets. Members receive regular mailings unless they request not to be contacted.

Difficulties in enumeration[edit]

The fact that the religion is diffuse and proportionally small are major barriers to demographic research by outsiders. Even in the United States, where significant resources are dedicated to gathering data, the Baháʼí Faith is often omitted from religious surveys due to the high sample size required to reduce the margin of error. In some countries the Baháʼí Faith is illegal and Baháʼís endure some degree of persecution, making it difficult for even Baháʼís to maintain a count.[citation needed], a website dedicated to collecting statistics on world religions, made the following comments about Baháʼí membership:

As with most religious groups, organizationally reported adherent counts include significant numbers of nominal members, or people who no longer actively participate, yet still identify themselves as adherents. There are valid arguments that some of the "mass conversions" have resulted in adherents with little or no acculturation into the new religious system. As is typical with a religious group made up primarily of converts, Baha'is who drift from active participation in the movement are less likely to retain nominal identification with the religion -- because it was not the religion of their parents or the majority religion of the surrounding culture. On the other hand, there are no countries in which people are automatically assigned to the Baha'i Faith at birth (as is the case with Islam, Christianity, Shinto, Buddhism, and other faiths), so their numbers aren't inflated with people who have never willingly participated in or been influenced by the religion while adults. On balance, while official Baha'i figures are not a measure of active participants, the proportion of participating adherents among claimed adherents is thought to be higher than average among the "major religions" on this list.[7]

Most denominations make no effort at all to maintain a national membership database and must rely on local churches or surveys of the general population. Local church membership rolls are often maintained poorly because there may be no need for an official membership list (Baháʼís at least must maintain accurate voting lists) and local congregations sometimes do not provide their denomination's membership data even when asked.[citation needed]

Baháʼí sources[edit]


  • As early as 1991 official estimates were of "more than five million Baháʼís",[9] which is still in use as of 2017.[3]
  • The Department of Statistics, Baháʼí World Centre, does not provide an estimated total, but publishes more concrete statistics, such as the representation among countries, languages, and tribes. In 2001 the department claimed there were 11,740 local Spiritual Assemblies, and 127,381 localities in 236 countries and territories.[10]
  • A 1997 statement by the NSA of South Africa wrote: "…the Baháʼí Faith enjoys a world-wide following in excess of six million people."[15]
  • In 1989 the journal Religion published an article by Baháʼís Moojan Momen and Peter Smith.[16] They observed that in the 1950s there were "probably in the region of 200,000 Baháʼís world-wide. The vast majority of these (over 90%) lived in Iran." And by the end of the 1960s, "we 'guestimate' that there may now have been about one million Baháʼís."
  • A 1987 report, published in the United States Baháʼí News reports 4.74 million Baháʼís in 1986 growing at a rate of 31% over 1979, or 4.4% per year on average.[17]


  • The first known survey of the religion comes from an unpublished work in 1919–1920 gathered by John Esslemont and had been intended to be part of his well-known Baháʼu'lláh and the New Era.[18] In it, consulting various individuals, he summarizes the religion's presence in Egypt, Germany, India, Iran, Iraq, Turkestan, and the United States. It did not arrive at a total but did have some regional statistics based on some individual reports.
  • During his ʻAbdu'l-Bahá's tour of America several newspapers made claims of how large the religion was, with figures normally in the range of millions of people.
    • In 1912, a reporter in Salt Lake City claimed ʻAbdu'l-Bahá said the religion had "10,000,000 followers in the world."[19]
    • On June 16, 1912, a news report introduced him as the "Persian religious leader and spiritual and temporal head of the 14,000,000 of Baháʼís scattered throughout the world."[20]
    • On April 24, 1912, a newspaper article said "Baháʼísm now has 15,000,000 adherents scattered throughout the world, several hundred thousand of whom are in the United States and Canada."[21]
    • On April 12, 1912, a newspaper introduced him as "head of one of the newest and most thriving religions in the world, numbering 20,000,000 souls among his followers, of whom several hundred souls are in New York."[22]
    • On September 9, 1911, a news report about ʻAbdu'l-Bahá's visit to London claimed "at a moderate estimate, three million followers."[23]

Other sources[edit]

Many sources mentioning the number of Baháʼís in the world are deriving their information from just a few sources, which themselves review Baháʼí sources among many censuses and surveys.[citation needed] When a number is estimated for a particular year, future years are estimated based on growth rates.[citation needed]

  • The World Christian Database (WCD), and its predecessor the World Christian Encyclopedia. The WCD reviewed religious populations around the world and released results of their investigations at various times, most recently in 2010. The Baháʼí Faith has consistently placed high in the statistics of growth over these various releases of data.[2][24][25] A review, by graduate students in the Department of Sociology at Princeton University, examining the reliability and bias of the World Christian Database found it "highly correlated with other sources of data" but "consistently gave a higher estimate for percent Christian." In conclusion they found that, "Religious composition estimates in the World Christian Database are generally plausible and consistent with other data sets."[26] However, one Danish researcher, Margit Warburg, stated that the Baháʼí figures reported in WCE for some Western countries are highly exaggerated. For instance, she states, the World Christian Encyclopedia reports an estimated 1,600 Baháʼís in Denmark in 1995 and 682,000 Baháʼís in the USA in 1995. According to her, the Baháʼís themselves do not acknowledge such numbers; the number of registered Baháʼís in Denmark, in 1995, were about 240 and in the USA were about 130,000.[27]
  • Association for Religious Data Archives (ARDA). The archive is "a collection of surveys, polls, and other data submitted by the foremost scholars and research centers in the world." It gathers data from, "the US Census Bureau's International Data Base, the US State Department's International Religious Freedom Report, the United Nations Human Development Reports, and others"[28] including World Christian Database.[29]

In 2012 the Pew Research Center published a report on the Global Religious Landscape. Baháʼís were grouped in with the category "Other Religions" that included Sikhs and Zoroastrians. Pew said, "Because of the lack of data on these faiths in many countries, the Pew Forum has not attempted to estimate the size of individual religions within this category..."[30]

2005 and newer[edit]

  • In April 2017, The Economist reported that there were more than 7 million Baháʼís in the world.[31]
  • In 2016 the Yearbook of International Religious Demography 2016 noted just over 7.8 million Baháʼís in the world in 2015, having grown at an overall rate of 2.79% across the century 1910 to 2010.[32] The countries with the largest Baháʼí populations in 2015 were, (starting with the largest): India, the US, Kenya, Viet Nam, Congo DR, Philippines, Zambia, South Africa, Iran and Bolivia, ranging upwards from 232,000 to just over 2 million in India.[33]
  • In 2013 the book The World's Religions in Figures: An Introduction to International Religious Demography wrote, "The Baha'i Faith is the only religion to have grown faster in every United Nations region over the past 100 years than the general population; Bahaʼi was thus the fastest-growing religion between 1910 and 2010, growing at least twice as fast as the population of almost every UN region."[6]
  • The 2010, Association of Religion Data Archives estimate is of 7.3 million (based partly on World Christian Encyclopedia).[28]
  • In 2010, The World Religion Database states there are 7.3 million Baháʼís.[25]
  • In 2010, Encyclopædia Britannica estimated a total of 7.3 million Baháʼís residing in 221 countries,[1] based partly on the World Christian Encyclopedia.[citation needed]
  • The World Factbook states that Baháʼís make up 0.12% of the world based on a 2007 estimate,[34] corresponding to 7.9 million people.
  • The 2005 Association of Religion Data Archives estimate is of 7.6 million[35] which is also echoed elsewhere.[36]
  • In 2005, the Encyclopedia of Religion, second edition, records that:
"In the early twenty-first century the Baháʼís number close to six million in more than two hundred countries. The number of adherents rose significantly in the late twentieth century from a little more than one million at the end of the 1960s."[37]

2000 to 2004[edit]

  • In 2004, the Encyclopedia of the Modern Middle East and North Africa vol 1, reported that "By 1900, the community… had reached 50,000-100,000… Baháʼís worldwide [are] estimated in 2001 at 5 million."[citation needed]
  • In 2003, World Book Encyclopedia reported that "there are about 5,500,000 Baháʼís worldwide."[38]
  • In 2001,World Christian Encyclopedia, 2001,p 4 estimated 7.1 million Baháʼís in the world in 2000, representing 218 countries. The same source estimated 5.7 million in 1990.[39] Its definition of membership is broader than the official Baháʼí definition and would include people who attend Baháʼí gatherings regularly even if they have not declared their faith or persons who state they are Baháʼís in government censuses as a result of reading about the religion or hearing about it on the radio.
  • In 2000, Encyclopædia Britannica estimated a total of 7.1 million Baháʼís residing in 218 countries,[40] based partly on the World Christian Encyclopedia.[citation needed]
  • In 2000, Denis MacEoin wrote in the Handbook of Living Religions that:
"the movement has had remarkable success in establishing itself as a vigorous contender in the mission fields of Africa, India, parts of South America, and the Pacific, thus outstripping other new religions in a world-wide membership of perhaps 4 million and an international spread recently described as second only to that of Christianity. The place of Baha'ism among world religions now seems assured."
  • estimates 7 million Baháʼís in 2000 based on Baháʼí sources, research from the World Christian Encyclopedia, 2000, and the Population Reference Bureau.[41][7]

1980s to 2000[edit]

  • In 1998, the Academic American Encyclopedia said that the Baháʼís "are estimated to number about 2 million."[citation needed]
  • In 1997, Dictionary of World Religions estimated "five million Baháʼís" in the world.[42]
  • In 1997, Religions of the World published: "today there are about 5 million" Baháʼís.[citation needed]
  • In 1993, the Columbia Encyclopedia published: "There are about 5 million Baháʼís in the world."[citation needed]
  • In 1995 the HarperCollins Dictionary of Religion states: "In 1985, it was estimated that there were between 1.5 to 2 million Baha'is, with the greatest areas of recent growth in Africa, India, and Vietnam."[citation needed]

1950s to 1980s[edit]

  • Paul Oliver wrote in World Faiths that there were "approximately five million Baháʼís" in 1963.[43]

Adherents by country[edit]

Sources on numbers of Baháʼís by country include official government censuses, self-reported Baháʼí data, and estimates from third-party organizations. The figures from these sources have often varied widely.

From the early 1960s until the late 1990s, the Baháʼí population of the United States went from around 10,000 to 140,000 on official rolls, but the number of members with known addresses in 1998 was only about half the total.[44] In recent years, the United States Baháʼí community has been releasing detailed membership statistics.[45][46] Ridvan 2020 Annual Report of the Baháʼís of the United States reported 77,290 Baha'is with good addresses.[47]
