* An estimate of the number of pioneer workers needed for initial church planting among unreached people groups by country. 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 by country. Some workers may already be onsite. Many more workers are needed beyond this initial estimate.
