An ethnic religion is generally defined by the ethnicity of its adherents, and conversion essentially equates to cultural assimilation into that ethnoreligious group. Ethnic religions are distinguished from religions that actively seek converts worldwide, regardless of ethnic affiliation. In contrast, ethnic religions have (diasporas excluded) limited geographic scope, and membership is (by definition) determined by ethnic affiliation.
