The 10/40 Window is a term coined by Christian missionary strategist Luis Bush in 1990 to refer those regions of the eastern hemisphere located between 10 and 40 degrees north of the equator, a general area that in 1990 was purported to have the highest level of socioeconomic challenges and least access to the Christian message and Christian resources on the planet.

The 10/40 Window concept highlights these three elements: an area of the world with great poverty and low quality of life, combined with lack of access to Christian resources.

Non-Christians in the 10/40 Window by Religion

The first edition GIS analysis maps highlighted the three major religious blocks in the 10/40 Window, specifically the majority Muslim, Hindu and Buddhist nations. Population estimates at the time for the year 2000 (from Operation World) were given as:

  • 28 Muslim Countries, 1.1 Billion population est (2000)
  • 2 Hindu Countries, 1.1 Billion population est (2000)
  • 8 Buddhist Countries, 237 Million population est (2000)

Later updates have been based more on census data and other estimates rather than forward-looking population estimates. The cited reference provides the following estimate of "unreached" non- Christian populations in the Window:

  • 865 million Muslims
  • 550 million Hindus
  • 275 million Buddhists
  • 140 million in 2550 tribal groups (mainly animist)
  • 17 million Jews
