What "unreached" means

A people group is unreached when there is no indigenous community of believers large enough to evangelise the rest of the group without outside help — commonly measured as under 2% evangelical. Frontier groups are the least reached of all: fewer than 1 in 1,000 follow Jesus and there is no known movement to Christ.

"Unreached" is a statement about access, not about the worth of a people or the sincerity of anyone's faith.
