1. Religion which occurs in small, local communities which does not adhere to the norms of large systems. Folk-urban typology was developed by Robert Redfield as a basis for the comparison of societies, and for the study of urbanization.
2. In a wider sense, folk religion is the appropriation of religious beliefs and practices at a popular level. This may occur as much in urban as in rural environments, and may also be the way in which individuals or groups belonging to mainstream religions practise their religion: it may be at considerable variance from what is officially supposed to be the case, and is thus also referred to as non-official religion.
