* 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-unit (single person or married couple) per 50,000 living in an unreached people group by country, or for example one team of four worker-units per 200,000 people. Some workers may already be onsite. Many more workers are needed beyond this initial estimate.
Joshua Project data is drawn from many sources and of varying accuracy depending on source and editorial decisions. Populations are scaled to the current year. Other data may have varying ages. We welcome updates.
Joshua Project occasionally adjusts profile text from third party sources. This is done to avoid confusion regarding the current reality of a people group, to fix grammar and spelling and to avoid potentially offensive wording.
A displayed zero can mean true zero, a very small rounded number or sometimes unknown. Blanks mean an unknown value.
Data is not as precise as it appears. Values for %Christian Adherent and %Evangelical (which determine unreached status) are often informed estimates, some more accurate than others. We recommend against using %Christian Adherent and %Evangelical to calculate absolute numbers.
Joshua Project makes every effort to ensure that the subject in an image is in fact from the specific people group. In rare instances a representative photo may be used.
