10/40 Window

In brief: The 10/40 Window refers to the section of Africa, Europe, and Asia between 10 and 40 degrees north of the Equator. It encompasses Saharan and Northern Africa, as well as almost all major Asian nations other than Russia. Roughly two-thirds of the world population lives in the 10/40 Window. The term was coined by Christian missionary strategist Luis Bush to refer to the region of the world with the least exposure to Christianity. The 10/40 Window is populated by peoples who are predominantly Muslim, Hindu, Buddhist, Animist, Jewish and Atheist. Many nations in the 10/40 Window are openly hostile to evangelization and Christianity.
