What is the 10/40 window?
The 10/40 Window is the area of the world between latitudes 10 degrees and 40 degrees north of the equator in the Eastern Hemisphere, covering North Africa, the Middle East, and Asia. The window contains most of the world's areas of greatest physical and spiritual needs, most of the world's least-reached peoples and most of the governments that oppose Christianity. Two-thirds of the world's population is located in the 10/40 window. In areas of the 10/40 window, there is only one missionary for every one million people. In the year 2000 there were over one billion Muslims and Hindus in the 10/40 window. Some of the problems in the 10/40 window are starvation, disease, economic disaster, religious persecution, government and political breakdown, and insufficient living conditions. But far above all of these, is the need of the gospel of Christ.
Within this 10/40 window are:
• Most of the world's unreached peoples.
• Two-thirds of the world's population, although only one-third of the earth's land area.
• The 10/40 window outlines the heartlands of the major non-Christian religions of the world Tribal, Hindu, Unreligious, Muslim and Buddhist.
• 865 million unreached Muslims or Islamic followers in 3330 cultural sub-groupings.
• 550 million unreached Hindus in 1660 cultural sub-groups.
• 150 million unreached Chinese in 830 groups.
• 275 million unreached Buddhists in 900 groups.
• 2550 unreached tribal groups (which are mainly animistic) with a total population of 140 million.
• Forming a smaller -- though important -- unreached group are the 17 million Jews scattered across 134 countries.
• Eight out of ten of the poorest of the world's poor enduring the world's lowest quality of living.
• Only 8% of the world's missionary force and 0.01% of the income of the world's Christians.
• Of the 55 least evangelized countries, 97% of their population lives within the 10/40 Window.
The 10/40 Window confronts us with several important considerations: first, the historical and biblical significance; second, the least evangelized countries; third, the dominance of three religious blocs; fourth, the preponderance of the poor; fifth, the unreached ethnolinguistic people groups; sixth, the least evangelized megacities; and seventh, the strongholds of Satan within The 10/40 Window.
