The 10/40 Window is the area of the world between 10 and 40 degrees latitude 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 the most anti-Christian governments in the world. Two-thirds of the world’s population is located in the 10/40 window. More than 95% of the world’s unreached people live in this area. In areas of the 10/40 window, there is only one missionary for every one million people.

Some of the problems of the 10/40 window are starvation, disease, economic disaster, religious persecution, government and political breakdown, and insufficient living conditions. About 80% of the poorest of the world’s poor live in this region, enduring humanity’s lowest standards of living. But far above all of these, is the need of the gospel of Christ. The gospel is the hope for all nations, including the ones in the 10/40 window. “The harvest is plentiful, but the workers are few” (Matt 9:37). As we can see, His statement is no less true today
