The Bible Poverty Index (BPI) is a classification system used to measure the progress of Bible engagement in a language. With the BPI, each language can be viewed according to it's Bible translation, publication, distribution, and engagement status. The two primary goals are to have ZERO languages in the "No Bible" category, and to have EVERY language in the "Engagement" category.
Data factors feeding into the list include: Bible translation progress, including Full, New Testament, or Portions completed; print, audio, video, and digital formats; Jesus Film translations; and likelihood of engagement of official language by country. Sources for the BPI list include: International Mission Board, Joshua Project, JesusFilm, Finishing the Task, Progress.Bible (SIL), eBible, Faith Comes By Hearing, and 4K Mapping (YWAM).
