Defining The Unreached

An unreached people group, or UPG, is a society among which there is no established local community of believers. This small to nonexistent church often also lacks the resources and is relatively insufficient to evangelize their people group and make Christ known in the broader population without outside help.

According to the Joshua Project, a people group is considered unreached based on the following criteria:


Evangelical Christian
Christian adherent (one who claims any form of the Christian religion)
Total people groups in the world
Unreached People Groups
% Unreached People Groups
7.83 bn
Population of the world

people worldwide are unreached
of the world population is unreached


People group

"For evangelization purposes, a people group is the largest group within which the Gospel can spread as a church planting movement without encountering barriers of understanding or acceptance” (1982 Lausanne Committee Chicago meeting). Understanding or acceptance barriers include things like ethnicity, religion, culture, and language.

The biblical focus of unreached

Reaching the unreached is not just a mission strategy, its roots are found in the Bible. From Genesis to Revelation, the ultimate desire of God is revealed for His name to be known and His glory enjoyed among all the nations of the world.

  • The LORD reigns, let the earth rejoice; let the many coastlands be glad! (Ps. 97:1)
  • Be still and know that I am God. I will be exalted among the nations I will be exalted in the earth. (Ps. 46:10)
  • Let the peoples praise you, O God; let all the peoples praise you! (Ps. 67:5)
  • Declare His glory among the nations his marvelous works among all the peoples. (Ps. 96:3)
  • Praise the LORD, all nations! Extol him, all peoples! (Ps. 117:1)
  • For the earth will be filled with the knowledge of the glory of the LORD as the waters cover the sea. (Hab. 2:14)
  • Yes, LORD, walking in the way of your laws, we wait for you; your name and renown are the desire of our hearts. (Isa. 26:8)
  • I am the Lord; that is my name, my glory I give to no other. (Isa. 42:8)
  • Everyone who is called by my name, whom I created for my glory, whom I formed and made. (Isa. 43:7)
  • Ascribe to the LORD, O families of nations, ascribe to the LORD glory and strength, ascribe to the LORD the glory due his name. Bring an offering and come before him; worship the LORD in the splendor of his holiness. (1 Chron. 16:28-29)
  • Behold, a great multitude that no one could number from every nation, from all tribes, peoples and languages, standing before the throne and before the Lamb…crying out with a loud voice, β€œSalvation belongs to our God who sits on the throne, and to the Lamb!” (Rev. 7:9-10)

God’s desire is for all people to be reconciled to Him (1 Timothy 2:4). The Great Commission, Jesus’s mandate for all His disciples in Matthew 28:19, continues this worldwide scope: “Go therefore and make disciples of all nations.” Nations, the Greek word ethne, means all people groups of the world. God’s heart is that the Gospel would be proclaimed in every tribe, tongue, nation, and people group.


The Great Imbalance

Despite Christ’s call to β€œGo into all the world and proclaim the Gospel to every creature,” less than 2% of missional resources and approximately 3% of cross-cultural workers go to serve among unreached people groups. This is what missiologists refer to as The Great Imbalance. This disparity of missional resources results in the Gospel rich getting richer at the expense of the Gospel poor.

Followers of Christ have been entrusted with the Gospel message (2 Corin. 5:18-20) and have been commissioned with the task to go and make disciples of all people groups. The reality that 42% of the world’s population is unreached with the Gospel, signals that this task is unfinished (Matt. 24:14).

Our call is to go where they have not heard (Rom. 10:14-15, 15:20). At TRIAD, we are spurred on by our worship and love of the King, by the reality of the unfinished task, and the ultimate vision of every tribe, tongue, nation, and people group coming together to praise our God (Rev. 7:9-12).
