* An estimate of the number of pioneer workers needed for initial church planting among unreached people groups. Estimates are calculated only for unreached people groups and are based on ratio of 1 worker for every 50,000 individuals living in an unreached people group. Some workers may already be onsite. The country estimate is a summation of the unreached people group estimates. Many more workers are needed beyond this initial estimate.
