How many people groups are there in the world? Some say 27,000. Others say 16,000. Some suggest 12,000. Still others say 10,000. Which numbers are correct? Could they all be correct?

The many different answers to this question often cause confusion. Different sources quote significantly different numbers. If we are commanded to make disciples of all people groups, just how many are there? But before trying to answer that, an example might help illustrate why the confusion exists. Suppose someone innocently asked ... What is the largest country? What is the answer? It all depends on what is meant by "largest." The answer is Russia if largest refers to geographic land area. The answer is China if largest refers to population. The answer is the United States if largest means financially. All are different, yet are correct answers to the same simple question. The underlying issue is definitions ... what is meant by" largest?" So the core question is what is meant by the term " people group?"

What is A People Group?
The Lausanne 1982 people group definition says "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".

The Joshua Project list is just a step toward a yet to be defined larger peoples list. From a church planting perspective, a complete peoples list would be a unimax peoples list. Unimax people are defined as “the maximum sized group sufficiently unified to be the target of a single people movement to Christ, where “unified” refers to the fact that there are no significant barriers of either understanding or acceptance to stop the spread of the gospel.” (“ Finishing the Task," Perspectives on the World Christian Movement, Winter and Koch, 1999)

There are two barriers cited, (1) understanding, and (2) acceptance. The barrier of understanding suggests that language always is important when defining a people group. If for a particular situation the understanding barrier is more important than the acceptance barrier then defining people group by language, perhaps exclusively by language, is appropriate. And this seems to be the case in most cultures and situations.

In other situations the acceptance barrier may be as high, or perhaps higher, than the understanding barrier. The reasons for lack of acceptance may include caste, religious tradition, location, common histories and traditions, and other subtle cultural distinctives. In these situations the barrier of acceptance should be considered on an equal footing with the barrier of understanding, and sometimes acceptance is a higher barrier than is the barrier of understanding.

Understandability and Acceptance Top

The 1982 peoples definition began a process of identifying the unreached peoples of the world that is still not complete. Various ways of defining people groups has lead to several types of peoples lists and sometimes confusing counts of peoples.

Varying the Definition of a People Varies the Resulting Lists Top

Ethno-linguistic Peoples Lists
Because of the remarkable language research compiled in the last 100 years, the first people group lists have generally been ethno-linguistic, meaning that a people generally was defined by language and/or dialect. Because of language research and the somewhat definable nature of language, ethno-linguistic peoples lists generally have uniform definitions across all countries and tend to be an "apples-to-apples" comparison. Ethno-linguistic peoples lists have great usefulness, particularly for language-oriented outreach and ministries.

Ethnic Peoples Lists Top
While language is a key barrier to understanding, in parts of the world factors other than language form barriers of acceptance across which the Gospel will not naturally flow. For church planting purposes, it is helpful to allow factors other than language to define the boundaries of a people group. An ethnic peoples list, in addition to language, allows distinctives such as religion, caste and culture to define a people group.

In parts of the world where peoples are defined by their language an ethnic peoples list and an ethno-linguistic peoples list are virtually the same. However in places like South Asia, parts of North Africa and China, where religion, caste and culture are more determinative than language in defining a people group, an ethnic peoples list and an ethno-linguistic list can be quite different. For example, in India there are approximately 450 ethno-linguistic people / language groups but over 2,300 ethnic people groups when caste, religion and cultural factors are considered.

Does moving from Ethno-linguistic to Ethnic Peoples get messy?
Yes. Ethno-linguistic peoples lists tend to have uniform definitions and global standards and generally yield "apples-to-apples" results. However, an ethnic (cultural-ethno-linguistic) peoples list allowing language, religion, caste and/or cultural distinctives to define a people group can occasionally introduce a bit of "apples-to-oranges" comparison. National and local people group researchers in one area of the world may use slightly different definitions based on their perception of onsite realities compared to another area of the world. Each may differently evaluate the barriers of acceptance. Even with these limitations, the hope is that an ethnic peoples list can help continue to define the church planting task of the Great Commission.

Is the Joshua Project list a complete Unimax Peoples list? Top
No. Unimax peoples may involve distinctives such as education, political and ideological convictions, historical enmity between clans or tribes, customs and behaviors, etc. that are not considered in the current Joshua Project list of ethnic peoples. In certain parts of the world such as South Asia, where extensive caste research has been done, a much clearer church planting picture is emerging. In these areas an ethnic peoples list is moving closer to a unimax peoples listing. In other parts of the world, there will be barriers of acceptance that will only be determined once workers are on-site. Therefore, all lists of peoples will be estimates until the task is completed. While the Joshua Project list offers a certain level of understanding regarding people group church-planting needs, it is not a complete unimax peoples list. The World Christian Encyclopedia estimates approximately 27,000 total unimax peoples.

What if Country Boundaries are Ignored? Top
All the above models consider country boundaries when defining people groups. For example, if the Tatar are in 21 Central Asian countries they are counted 21 times. Some hold that in the purest sense people groups should be counted without reference to political boundaries. The suggestion is that modern country boundaries did not exist when the command of Matthew 28:19 "to make disciples of all the ethne" was given. Others suggest that in many cases political boundaries do not distinguish peoples. The "pure peoples" model counts the Tatar living in 21 Central Asian countries as one people group, not 21. By following standard Registry of Peoples (ROP) coding, the Joshua Project list allows country boundaries to be counted or ignored as desired. The current Joshua Project count for peoples-by-country is 16,304 and the count for pure peoples is 9,871 .

Model Strengths and Weaknesses
The various models have different strengths and serve different purposes. An ethno-linguistic peoples list has a somewhat quantifiable criterion namely language, and serves as a helpful target for language oriented ministries such as Bible Translation, radio broadcasting, Jesus Film production etc. An ethnic peoples list considers non-language distinctives which create significant barriers of acceptance. An ethnic peoples list presents a church planting target that begins to quantify some of the acceptance barriers. An estimated model serves as a reminder of the yet to be quantified, ultimate task.

Summary of People Group Counts Top

Other Factors in People Group Counts
When comparing lists of peoples care should be taken to understand all factors. For example, some lists have population cutoff points. The original Joshua Project list of approximately 1,600 peoples only considered people groups greater than or equal to 10,000 in a given country. The India Missions Association (IMA) list for India cuts off the population at 10,000, yielding only about 950 groups. Another example is the K.S. Singh list for India peoples which often breaks people groups by state boundaries, yielding a total of about 4,700 groups for India. Understanding these kinds of factors helps explain the very different counts that result.

So What is the Answer? Top
So after all that, what is the answer to the simple question of how many people groups are there? It depends, if referring to ethno-linguistic peoples about 13,000 and if referring to unimax peoples (the church planting perspective) about 27,000, of which about 16,000 are listed here as 'ethnic' (cultural-ethno-linguistic) peoples'. Or if referring to ethnic (cultural-ethno-linguistic) peoples without reference to country boundaries about 10,000. All are right answers depending on the persepective.
