Disclaimers:
  1. 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 suggested updates.
  2. A displayed zero can mean true zero, a very small rounded number or sometimes unknown. Blanks mean an unknown value.
  3. The data is sometimes 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.
  4. 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.
  5. Joshua Project may be able to provide more information than what is published on this site. Please contact us.
  6. On-the-ground reality may vary from what is presented here. Before making travel plans based on data presented here, please confirm with other sources to the extent possible.
