Since countries collect data on ethnicity in different ways and for different purposes and since the ethnocultural composition of a country could vary widely from country to country, no internationally relevant criteria or classification can be recommended. Religion can be defined as either religious or spiritual belief of preference, regardless of whether or not this belief is represented by membership of or affiliation with an organized group having specific religious or spiritual tenets. For the purposes of international comparisons, each sect should be shown as a subcategory of the religion to which it belongs.
