unreached people group

In Christianity, an unreached people group refers to an ethnic group without an indigenous, self-propagating Christian church movement. Any ethnic or ethnolinguistic nation without enough Christians to evangelize the rest of the nation is an "unreached people group". It is a missiological term used by Evangelical Christians. The Lausanne Committee for World Evangelization defines a people group as "the largest group within which the Gospel can spread as a church planting movement without encountering barriers of understanding or acceptance." "Nation" is sometimes used interchangeably for "people group". The term is sometimes applied to ethnic groups in which less than 2% of the population is Evangelical Christian.
