What Are Unreached People Groups, Anyway?

There are lots of ways to look at the Earth’s population. But if your goal is to plant churches that give everyone access to the gospel, some perspectives are more helpful than others.

What a map may not tell you

Maps are useful for navigating from point A to point B, but the political boundaries on a map don’t reveal much about the people who live there.

• A single country like Papua New Guinea can be home to over 1,000 distinct people groups—each with its own language, culture and religious traditions.
• The country of Chad is home to more than 200 distinct tribes and ethnic groups.
• Even Japan, though less diverse, is home to more than 40.
• Some groups, like the Fulani of West and Central Africa, stretch across multiple countries.
• Global migration brings people from many groups into new places. Some blend together. Others hold tight to their languages, cultures and identities.

The concept of “people groups” has had a significant impact on mission work for decades and led to the launch of ministries like Pioneers. Of course, people group thinking builds on ideas that go back much further—even to the book of Genesis, which describes one family meant to bless all the families of the earth. God sent His Son to be born into that family, making a way for all who receive Him to become God’s sons and daughters. We see the vision fulfilled in Revelation, which describes a great multitude worshiping God—people from every tribe, language, people and nation.

The people group paradigm

A group of mission leaders gathered in the 1980s to wrestle with that question. They sought to clarify and define the remaining missionary task. A few basic definitions have emerged that still influence how we approach ministry today.

• A people group is “a significantly large grouping of individuals who perceive themselves to have a common affinity for one another because of their shared language, religion, ethnicity, residence, occupation, class or caste, situation, etc., or combinations of these.” That’s a sociological definition.
• For evangelistic 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.” That’s a missiological definition.
• 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 outside assistance.” This tells us where cross-cultural missionaries are most needed. If you want to make a list of them, though, you have to add metrics (like percentages). Note that most groups considered unreached have some Christians among them.
• There are also degrees of “reachedness.” Some groups are said to be partially reached, superficially reached or minimally reached. About one in four people in the world—1.9 billion people—belong to frontier people groups. These are the “least reached,” with less than one person in a thousand identifying as a Christian in any sense of the word.

Still with us? Let’s add one more definition.

• An unengaged people group is “one where there are no known efforts focused on establishing self-sustaining churches consistent with evangelical faith and practice.”

A people group becomes engaged when:

• There is sustained activity to share Christ and make disciples
• There are efforts to establish self-sustaining churches
• The work occurs in culturally appropriate and locally relevant ways

That’s what we want to see happen! You, too? We’re happy to link arms with others who share this passion to share the gospel, make disciples and plant churches that can multiply and reach whole communities.

An important note: Most people group lists focus on ethno-lingistic groupings. But they don’t tell the whole story. Other factors play a part—like social status, caste and especially geography. Pioneers is working to engage people in more unreached people groups and in more unreached places—places that lack gospel access. And the way we do that is by planting churches.

If that’s your heartbeat, let’s talk.
