What Is the 10/40 Window

What Are Some 10/40 Window Statistics?

Several organizations collect and study 10/40 window statistics. Their findings help missions organizations develop effective ministries to help the people of the area.

Here are some statistics of this region:


  • There are 5.32 billion people who live in the revised 10/40 window.[1]
  • There are 8,882 distinct people groups in the revised window. Of those, 6,147 or 69.2% are considered uncontacted (3.28 billion people).[2]
  • Some of the largest people groups in the world live inside the 10/40 window, including Shaikh, Yadava, Turks, Moroccan Arabs, Pashtun, Jat and Burmese.[3]
  • Windows International estimates that 1.6 billion of these people have never had the chance to hear about the love of Jesus Christ.[4]
  • The 10/40 window is also home to some of the poorest people in the world. This has caused ministries and humanitarian organizations to pour help into this region. It is reported that 87% of people living in this region are the poorest of the poor, living on an average of only $250 per family annually.[5]

How do statistics like these impact the ministry of GFA World inside the 10/40 window? 


GFA is transforming communities through Christ’s love in four main ways: 

  • Sponsoring and supporting national missionaries, who serve as the hands and feet of Christ as they minister to people’s physical and spiritual needs;
  • Sponsoring children to meet both their and their families’ needs in a variety of ways, including by providing education; 
  • Investing in community development so entire neighborhoods receive assistance like clean water, sanitation, etc., and 
  • Helping families in need of care or those impacted by disasters such as earthquakes, floods, fires and more. 

Through these ministries, people in this region find hope outside of their difficult circumstances.

GFA works in over 20 countries worldwide, focusing on serving those who have never once heard the Good News—especially those in the 10/40 window.

For over 35 years now, GFA has helped launch national workers in some of the neediest Asian countries, including areas with the most inaccessible people groups in the world.

We continue to be faithful in this region, as well as in Africa, to provide tangible help to those in need and to bring the Good News to people who have yet to learn about God’s love for them. It is our desire to minister to them and help them through ministries like education, health and practical gifts, or through the spiritual transformation of peaceful hearts, restored relationships and mended lives. We do this all in community and in partnership with the global Body of Christ.
