What is the 10/40 Window?
The 10/40 Window refers to the area of the world between latitudes 10 degrees south and 40 degrees north of the equator covering North Africa, the Middle East, and Asia. Many of the world’s least-reached people live in this area.

The Church of the Nazarene is at work in 30 of the 65 nations in the 10/40 Window.
- Nearly 4 billion people live here, including 90 percent of the world's poorest of the poor. It is estimated that 1.6 billion of these people have never had the chance to hear the Gospel of Jesus Christ - not even once!
- The seat of every major non-Christian religion - Islam, Buddhism, Hinduism, Animism, Atheism, and Sikhism - is headquartered in the 10/40 Window.
- In many of the 67 countries represented in the 10/40 Window, witnessing the Christian Gospel means death. Truly, the 10/40 Window remains the darkest and most inhospitable territory to the cause of Christ and represents the greatest remaining stronghold of Satan.
- Two-thirds of the world’s population (4 billion) live in the 67 nations of the 10/40 Window.
