The 10/40 Window is a helpful model to illustrate where the majority of unreached people groups remain. This is where the frontiers are, and it is where God is calling us to look in order to assist in completing the Great Commission.
The 10/40 Window is a rough illustration of where the majority of the work for world evangelization remains to be done. It is a box between the 10th and 40th latitudes north of the equator, closed in at each end as it enters the Atlantic and Pacific Oceans.
The 10/40 Window contains:
- Two-thirds of the world’s population though only one-third of the world’s land mass
- Most of the world’s unreached people groups
- The majority of the followers of Islam, Hinduism and Buddhism as well as the non-religious block
- The vast majority of the world’s poor who live on less than $2.00 per day
- Most of the world’s unreached people groups. As of 2015, 84% of the total number of unreached people groups were estimated to be in the 10/40 Window.
- For more up-to-date statistics and information on unreached peoples, please visit the website of the Joshua Project website, a research initiative seeking to highlight the ethnic people groups of the world with the least followers of Christ.
As the Church approaches the task of reaching all people groups with the Gospel, the 10/40 Window has become more of a focus to more sending congregations. It is also likely that the completion of the Great Commission and the return of Christ will be connected to the involvement of His Church in this region of the world!
A people group is…
“a significantly large ethnic/sociological grouping of individuals who perceive themselves to have a common affinity for one another. From the viewpoint of evangelization, this is the largest group within which the Gospel can spread as a church-planting movement without encountering barriers of understanding or acceptance.”
An unreached people group is…
“a people group among which there is no indigenous community of believing Christians with adequate numbers and resources to evangelize this people group without requiring outside (cross-cultural) assistance.”
