The 10/40 Window is the rectangular area of North Africa, the Middle East and Asia approximately between 10 degrees north and 40 degrees north latitude. The 10/40 Window is often called "The Resistant Belt" and includes the majority of the world's Muslims, Hindus, and Buddhists. The 10/40 Window includes several countries, such as Indonesia, that are close to 10 or 40 degrees north latitude and have high concentrations of unreached peoples. An estimated 4.43 billion individuals residing in approximately 8,811 distinct people groups are in the revised 10/40 Window. The 10/40 Window is home to some of the largest unreached people groups in the world such as the Shaikh, Yadava, Turks, Moroccan Arabs, Pushtun, Jat and Burmese. The 10/40 Window has several important considerations: first, the historical and Biblical significance; second, the least evangelized countries; third, the unreached people groups and cities; fourth, the dominance of three religious blocs; fifth, the preponderance of the poor; sixth, the strongholds of Satan within the 10/40 Window.
