Who are the Unreached?

Right now, over 3.2 billion people have little to no access to the Gospel. They belong to Unreached People Groups (UPGs) and Frontier People Groups (FPGs)- communities where less than 2% identify as evangelical Christians and where there are not enough believers to share the message of Jesus effectively.

Even more isolated than the unreached are the Frontier People Groups (FPGs)—communities where fewer than 0.1% of the population is Christian, and there are no known movements to Jesus. These groups have no churches, no local believers, and no Gospel presence. Without outside workers, entire generations will live and die without ever hearing the name of Christ.

Most of these groups live in what is known as the 10/40 Window, a region stretching across North Africa, the Middle East, and Asia. It is home to some of the largest and least-reached populations in the world.

...and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb...

The term “unreached” gained widespread recognition in the mid-20th century when mission leaders began identifying places where traditional missionary efforts had not taken root. In the 1970s, key figures in modern missions highlighted the need to reach ethnolinguistic groups - communities defined not just by geography but by shared culture and language.

An unreached people group (UPG) is generally defined as a distinct group with a common language and cultural identity, among whom there is no indigenous community of believing Christians capable of evangelizing their own people. According to missiologists, a group is considered unreached when less than 2% of its population is evangelical Christian and less than 5% is professing Christian. This means that without outside help - whether through prayer, support, or cross-cultural witness - they are unlikely to hear the gospel in their lifetime.

This definition is not about individual belief, but about access. Most unreached people have little to no opportunity to hear about Jesus in a way they can understand. They may live and die without ever meeting a Christian, hearing a Bible verse in their language, or knowing a local church exists.

Reaching the unreached isn’t just about geography, it’s about overcoming significant, layered barriers that prevent the gospel from taking root. These obstacles are often complex, overlapping, and deeply ingrained within the social, political, and spiritual fabric of these communities.

  • Geographic Barriers – Many unreached people live in remote or hard-to-access regions such as mountains, deserts, jungles, or politically restricted zones. Harsh terrain, limited infrastructure, and government restrictions can make consistent missionary presence extremely difficult.

  • Religious & Cultural Resistance – In many cultures, Christianity is perceived as a Western religion, incompatible with local values or traditions. Following Jesus can result in persecution, loss of livelihood, or rejection from one’s family and community.

  • Linguistic & Educational Gaps – Thousands of groups still lack a Bible in their heart language. Some languages have no written form, and others are spoken by very few people. 

  • Spiritual Opposition – Many unreached areas are places of deep spiritual bondage, where fear, animism, or other belief systems hold people captive. Evangelism in these contexts requires spiritual discernment, prayer, and long-term presence.

  • Lack of Workers – Despite the need, only about 3% of all cross-cultural missionaries work among the unreached. Many churches and sending organisations still focus on reached or more accessible places. Mobilising workers into the hardest places remains a significant challenge.

What’s more, many of the unreached live in parts of the world where Christianity is not just rare, but illegal or dangerous. Missionaries often cannot enter openly as religious workers. Creative access and tentmaking approaches - like teaching, business, or development - are often the only viable paths to presence. Even then, long-term fruit may take years to see, and workers must be prepared for slow, relational ministry.

To reach these groups, we need prayer-filled perseverance, creative strategies, and a long-term commitment. It’s not easy, but it’s essential.

Jesus commanded us to “Go and make disciples of all nations” (Matthew 28:19). Yet, despite having the greatest news in history, only 3% of Christian missionaries serve among the unreached. That means billions of people still live without access to the Gospel - without ever meeting a believer, hearing the name of Jesus, or holding a Bible in their own language.

 
At Pioneers Australia, we believe that everyone deserves the opportunity to know Jesus. God’s heart beats for the nations - every tribe, language, people, and culture. Scripture tells us that around His throne will be a great multitude “from every nation, tribe, people and language” (Revelation 7:9), worshipping the Lamb. But that vision has not yet been fulfilled. Entire people groups remain without a witness. That’s not just a mission statistic - it’s a spiritual emergency.

We exist to send and support Australian Christians who are passionate about seeing God glorified where He is not yet known, especially among those who have yet to hear. Whether through church planting, discipleship, business as mission, or community development, we long to see Christ exalted in places where His name is not yet worshipped.

This mission matters because eternity matters. Romans 10:14 reminds us, “How can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them?”  The unreached will remain unreached unless the Church takes intentional steps to go. This isn’t the task of a few - it’s the shared responsibility of us all. Whether by going, sending, praying, or giving, each of us is invited to play a part in what God is doing among the nations.
