Religious affiliation provides a useful indicator of aspects of the cultural diversity of Australia's society. The first edition of the Australian Standard Classification of Religious Groups (ASCRG) was published in 1996 and the second edition was published in 2005. The need for periodic reviews to reflect changes in the religious profile of Australia was foreshadowed when the ASCRG was first released.

This 2011 minor review of the ASCRG resulted in minimal change as shown in the 'Summary of Changes'.

The 2011 classification (along with its indexes and correspondences etc.) is available in Excel from the Downloads tab.

Classification uses

The ASCRG is for use in collecting, aggregating and disseminating data relating to the religious affiliation of the Australian population, or subsets of the population. It is used to classify religion data from ABS surveys and the Census of Population and Housing.

Data classified by religion can be used for policy and planning purposes related to the location and development of educational facilities and church buildings, aged persons' care facilities and services, and the provision of other social services by religious organisations. The classification enhances the usefulness of data used to assist in assigning chaplains and other care providers to hospitals, prisons, armed services, universities, and other institutions. It can also be used to determine the allocation of time to particular community groups on public radio and in other media, and is a useful tool in general sociological research.

First edition of the ASCRG 1996

The first edition of the ASCRG was developed by the ABS after extensive research of Australian and overseas literature, employment of statistical principles and techniques relating to statistical classification, and analysis of existing data relating to the religious profile of Australia (primarily data from the 1991 Census). This was supported by information and advice from academics and religious experts, and by consultation with community and religious groups interested in this topic.

In the classification, religious groups are arranged into progressively broader categories on the basis of similarity in terms of religious beliefs, religious practices and the cultural heritage of adherents. This results in those religious groups which are closely related in terms of their intrinsic characteristics being closely aligned in the structure of the classification. So people with similar religious beliefs are grouped together to produce a classification that is useful for both social analysis and planning purposes.

To make the classification as useful as possible, the number of persons affiliated to particular religious groups was a significant factor in developing the classification structure. Religious groups with a large number of affiliated persons, such as Christian denominations, were extensively identified in the classification. Those religions with a small number of affiliated persons were not separately identified in the classification structure but were included in appropriate residual categories.

The identification of individual religions or denominations in the classification, and the way in which they are grouped, does not imply the expression of any opinion on the part of the ABS concerning the relative merit or importance of particular religions or the people who practice them.

Second edition of the ASCRG 2005

The Second Edition (2005 revision) of the classification included changes to the structure of the classification and the renaming of some religious groups. At the four-digit level, the structure was expanded from 107 religious groups to 115. The number of narrow groups fell from 33 to 32. No changes were made at the broad group level.

Second edition (Revision 1) of the ASCRG 2011

The 2011 minor review of the classification resulted in minimal change. There was no change to the number of religious groups, narrow groups or broad groups.


A precise definition of the concept of religion, or of what generally constitutes a 'religion', is difficult, because of the intangible and wide-ranging nature of the topic.

Generally, a religion is regarded as a set of beliefs and practices, usually involving acknowledgment of a divine or higher being or power, by which people order the conduct of their lives both practically and in a moral sense.

This method of defining religion in terms of a mixture of beliefs, practices, and a supernatural being giving form and meaning to existence, was used by the High Court of Australia in 1983. The High Court held that 'the beliefs, practices and observances of the Church of the New Faith (Scientology) were a religion in Victoria'.

As part of the ruling, it was stated that:
    For the purposes of the law, the criteria of religion are twofold: first, belief in a Supernatural Being, Thing or Principle; and second, the acceptance of canons of conduct in order to give effect to that belief, though canons of conduct which offend against the ordinary laws are outside the area of any immunity, privilege or right conferred on the grounds of religion.
The above definition is useful in describing the nature of the entities included in the classification (apart from the major group 'No Religion', it includes all entities in the classification).

For instance:
  • Buddhism is universally accepted as a religion because, although it does not acknowledge a personal God, it contains elements of belief in supernatural principles as well as canons of conduct.
  • Confucianism is regarded as a religion, even though it involves no overt belief in the supernatural, because it provides a moral code for its adherents and because it contains elements of belief in supernatural principles.

But not all philosophies which involve beliefs about the nature of life or codes of behaviour are accepted as religions.

For instance:
  • Marxism, although regarded as a religion by some, is more generally regarded as a political philosophy based on a coherent set of beliefs, without any supernatural or spiritual component, and is therefore excluded from the classification.

So the extent of opinion as to what constitutes a religion, practical considerations, and generally held notions about the nature of philosophies, organisations and institutions all play a role in defining religion or identifying the concepts that underpin religion. These elements complement the more stringent notions of belief, accepted and widespread practices and canons of conduct and a supernatural being or principle included in the definition of religion. The definition provided here is regarded as sufficient for the purposes of the classification.


The scope of the classification is all religions and subsets of religions in the world as defined above. In practice, only those religious groups that have a significant number of affiliated persons in Australia are separately identified in the classification structure. However, all other religions are covered, notionally being included in the most appropriate residual category (Miscellaneous, Other, or Not elsewhere classified categories) of the classification. The code structure of the classification also allows the identification of religious groups not presently separately identified, if such a need arises.

'No religion' broad group

The classification also includes a 'No Religion' broad group which could be considered to be inconsistent with the basis of the classification as described above and outside the scope of the religion topic. It has been included for practical reasons and to make the classification more useful. Many statistical and administrative applications need to accommodate the whole range of responses to a question on religion, including the response 'No Religion'.
