This raises the question, how would the unreached numbers change if the less than 5% Christian Adherent criterion was removed?
Joshua Project Progress Scale. By combining the counts for “Stage 1” (Red) and “Stage 2” (Yellow) on the Joshua Project Scale, the result is the same as dropping the 5% Adherents criterion. Using the current data in the Joshua Project Progress Scale Summary listing and combining Stage 1 and Stage 2 (i.e. dropping the 5% Christian Adherents criterion) would result in 9,550 unreached peoples. In some ways this may be a more accurate measure of the true unfinished task.
