A NRM may be one of a wide range of movements ranging from those with loose affiliations based on novel approaches to spirituality or religion to communitarian enterprises that demand a considerable amount of group conformity and a social identity that separates their adherents from mainstream society. Scholars have estimated that NRM's now number in the tens of thousands worldwide, with most in Asia and Africa. Most have only a few members, some have thousands, and only very few have more than a million.
