In 1990 the Baha'i world faith itself claimed 110,000 adherents in the United States. A non-Baha'i historian from the University of Michigan who has scrutinized American Baha'i statistical practices has estimated a current (1999) figure of about 60,000 self-identified Baha'is in the U. But, with the ARIS survey now estimating 84,000 self-identified Baha'is in the U. in the year 2001, it appears that that historian's estimate is too low. It may also be noted that Baha'is are ranked as one of the world's ten largest international religious bodies and are among the top ten largest organized religions in the world, based on their current reported estimated membership.If there were 110,000 self-identified Baha'is in 1990 they would have ranked as the 9th largest U. religion (assuming that the other Kosmin figures are accurate). National Spiritual Assembly listing the number of U. If children are included and a slight undercount assumed, it is quite possible that there were closer to 100,000 (perhaps more) Baha'is in the U. Neo-pagan/Wiccan: There were 768,400 Neo-pagans (largest subset were Wiccans) in the U. in the year 2000, according to the Wiccan/Pagan Poll, conducted by the Covenant of the Goddess (Co G) beginning in late July, 1999.Christian respondents were further broken down into branches. The largest, most comprehensive surveys on religious identification were done in sociologists Barry A. Lachman and associates at the Graduate School of the City University of New York.
This would be the case especially if, as some Baha'is suggested in response to these findings, there were a high proportion of Baha'is who lived communally and did not have phones for each family, or were recent Iranian immigrants reluctant to identify their Baha'i affiliation over the phone because of past persecution.
If one excludes the "nonreligious" and "agnostic" categories from this list, then the Kosmin study would place Baha'is as the 9th largest religion in the U. Although the Kosmin study is well-respected, it should be noted that even with a random sample of such unprecedented size (113,000 respondents), the practical margin of error for this study was high for relatively smaller groups -- those with less than 300,000 individuals.
In this study, there a few more respondents who said they were Scientologists or Native American religionists than said they were Baha'is.
It is quite possible that growth within this group during this last 9 years has outpaced growth of some other groups, and that Baha'is are now among America's ten largest religions. [Online source: The Covenant of the Goddess (Co G) poll methodology is not comparable to methodology used in the Kosmin NSRI/ARIS studies, Harris Poll, Gallup polls, or Glenmary study.
But this proposition has not been verified empirically and similar claims of recent growth have also been made by the other groups. In 2004 the National Study of Youth and Religion conducted by the University of North Carolina at Chapel Hill (sample size: 3,370 teens nationwide) found that fewer than one-third of 1 percent of U. teens identified themselves as adherents of paganism (including Wicca).
