Religious Affiliation – New Zealand Standard Classification

"Religious affiliation is a variable of strong interest to religious organisations, social scientists, and can be used as an explanatory variable in studies on topics such as marriage formation and dissolution, fertility and income. In Australia and in Britain, religion is a variable that is used to derive measures of ethnicity. In New Zealand, religious affiliation is of particular significance for data users interested in Māori and in Pacific Island peoples.

Australian Standard Classification of Religious Groups

"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 and are included in the most appropriate residual category (Miscellaneous, Other, or Not elsewhere classified categories) of the classification.
