s and spiritual traditions may be classified into a small number of major groups, though this is not a uniform practice. This theory began in the 18th century with the goal of recognizing the relative degrees of
civility in different societies, but this concept of a ranking order has since fallen into disrepute in many contemporary cultures.
Religious demographics

One way to define a major religion is by the number of current adherents. The population numbers by religion are computed by a combination of census reports and population surveys, in countries where religion data is not collected in census, for example the United States or France. Results can vary widely depending on the way questions are phrased, the definitions of religion used and the bias of the agencies or organizations conducting the survey. Informal or unorganized religions are especially difficult to count.
There is no consensus among researchers as to the best methodology for determining the religiosity profile of the world's population. A number of fundamental aspects are unresolved:
* Whether to count "historically predominant religious culture
.
* Whether to count only those who actively "practice" a particular religion.
* Whether to count based on a concept of "self-identification as adherents".
* Whether to count only those who expressly self-identify with a particular denomination.
* Whether to count only adults, or to include children as well.
* Whether to rely on official government-provided statistics.
* Whether to use multiple sources and ranges or single "best source(s)".

as different "nations" or sects within ''religion'' itself, the "true
monotheism."
Daniel Defoe described the original definition as follows: "Religion is properly the Worship given to God, but 'tis also applied to the Worship of Idols and false Deities." At the turn of the 19th century, in between 1780 and 1810, the language dramatically changed: instead of "religion" being synonymous with spirituality, authors began using the plural, "religions", to refer to both Christianity and other forms of worship. Therefore,
Hannah Adams's early encyclopedia, for example, had its name changed from ''An Alphabetical Compendium of the Various Sects...'' to ''
A Dictionary of All Religions and Religious Denominations''.

) and paganism was multiplied considerably by
Josiah Conder's ''Analytical and Comparative View of All Religions Now Extant among Mankind''. Conder's work still adhered to the four-way classification, but in his eye for detail he puts together much historical work to create something resembling the modern Western image: he includes
Druze,
Yazidis,
Mandaeans, and
Elamites under a list of possibly monotheistic groups, and under the final category, of "polytheism and pantheism", he listed
Zoroastrianism, "Vedas, Puranas, Tantras, Reformed sects" of India as well as "Brahminical idolatry",

. The Parliament spurred the creation of a dozen privately funded lectures with the intent of informing people of the diversity of religious experience: these lectures funded researchers such as
William James,
D. T. Suzuki, and
Alan Watts, who greatly influenced the public conception of world religions.
In the latter half of the 20th century, the category of "world religion" fell into serious question, especially for drawing parallels between vastly different cultures, and thereby creating an arbitrary separation between the religious and the secular.
