Defining Indigenous Peoples: Key Criteria and International Perspectives

Ask ten scholars to define “indigenous people” and you will likely get ten different answers. That is not because nobody has tried. Since the 1970s, the United Nations, the International Labour Organization, and the World Bank have all attempted working definitions, each shaped by different mandates and political pressures. For students of tribal cultures, understanding these definitions matters because they determine who gets legal protection, land rights, and international recognition, and who gets left out.

Why there is no single legal definition 🔗

Indigenous communities exist on every continent, from the Sami of Scandinavia to the Adivasi communities of central India. Their histories, languages, and relationships with the state vary so widely that no single checklist fits everyone. Rather than forcing one rigid definition, international bodies have built working frameworks that describe common features without claiming to capture every case. This is a deliberate choice, not an oversight, and it explains why the frameworks you will study overlap but never fully agree.

The Cobo definition: where it all began 🔗

The most widely cited starting point comes from a 1972 study commissioned by the UN Sub-Commission on Prevention of Discrimination and Protection of Minorities, which appointed Ecuadorian jurist José Martínez Cobo as Special Rapporteur to study discrimination against indigenous populations.

The working definition his report produced describes indigenous communities as groups with historical continuity with the societies that existed on their territory before invasion or colonisation. These communities see themselves as distinct from the sectors of society now dominant in that territory, occupy a non-dominant position within it, and are committed to preserving and passing on their ancestral lands and ethnic identity to future generations, following their own cultural patterns, social institutions, and legal systems.

Four ideas anchor this definition: continuity with a pre-colonial past, self-perceived distinctiveness, non-dominant social status, and a determination to transmit identity forward. Notice that the Cobo definition does not ask how long a group has been isolated or how “traditional” its lifestyle looks. It focuses instead on historical relationship and self-perception, which is precisely why later bodies found it useful but incomplete.

Widening the lens: the 1983 and 1986 additions 🔗

The UN’s Working Group on Indigenous Populations, set up in 1982 to carry this work forward, soon realised the original Cobo definition risked excluding groups whose experience of colonisation did not fit a strict “pre-invasion” mould. So the definition was enlarged twice.

1983: descent, isolation, and alien state structures 🔗

In 1983, the Working Group added three criteria. Indigenous peoples are descendants of groups that were already present in a territory when other groups of a different culture or ethnic origin arrived there. Because of relative isolation from other segments of a country’s population, they have largely retained the customs and traditions of their ancestors. And they live, even if only in a formal sense, under a state structure that carries national, social, and cultural characteristics foreign to their own. These additions shifted the emphasis away from a single colonial moment and toward an ongoing structural relationship between indigenous communities and the modern state.

1986: the self-identification clause 🔗

Three years later, the Working Group added a clause that has since become central to almost every subsequent definition: any individual who identifies as indigenous, and who is accepted by the relevant community as one of its members, should be regarded as an indigenous person. This introduced what scholars call a two-part test, combining a subjective element, the person’s own identification, with an objective one, acceptance by the group itself. Neither element alone is treated as sufficient. The addition mattered because it placed the power of recognition back with indigenous communities rather than with outside governments or researchers.

ILO Convention 169: a working rulebook, not a definition 🔗

The International Labour Organization’s Convention No. 169, adopted in 1989, takes a deliberately different approach. Rather than offering a formal definition, it sets out identification criteria and openly states that self-identification is the fundamental test for deciding who the Convention protects.

Objective and subjective criteria for indigenous peoples 🔗

For groups described as indigenous, the Convention looks at descent from populations that inhabited a country, or a geographical region within it, at the time of conquest, colonisation, or the establishment of present state boundaries. It also considers whether the group retains some or all of its own social, economic, cultural, and political institutions, regardless of its current legal status. This is the objective side. The subjective side is self-identification as indigenous, which the Convention treats as a fundamental criterion that complements, rather than replaces, the objective conditions.

A separate test for tribal peoples 🔗

Convention 169 also covers tribal peoples as a distinct category. Here the criteria are social, cultural, and economic conditions that set the group apart from other sections of the national community, combined with a status that is regulated wholly or partly by the group’s own customs, traditions, or special laws. Both indigenous and tribal peoples receive the same protections under the Convention, but the routes to qualifying under each label differ slightly. This distinction is one reason the Convention has been used well beyond the handful of countries that formally ratified it, since governments and researchers often borrow its criteria as a practical shorthand.

The World Bank’s approach: geography over ideology 🔗

The World Bank takes a more operational route, since its main concern is protecting communities affected by development projects it finances. Its policy avoids offering a universal definition altogether, noting instead that no single accepted definition exists.

Instead, the Bank’s operational policy identifies indigenous peoples in a given geographical area through characteristics that may be present in varying degrees. These include close attachment to ancestral territories and the natural resources on them, self-identification as members of a distinct cultural group along with recognition of that identity by others, customary social and political institutions separate from those of the dominant society, an indigenous language often different from the national language, and production systems that are primarily subsistence-oriented.

Crucially, the Bank does not require a group to meet every characteristic. This flexible checklist lets project teams identify affected communities on the ground without getting stuck in definitional debates, which matters enormously in countries with dozens or hundreds of distinct tribal groups.

Five threads that run through every framework 🔗

Despite their differences, the Cobo definition, the ILO Convention, and the World Bank’s policy share five recurring threads. There is historical continuity with pre-colonial societies. There is a strong attachment to territory and natural resources. There are distinct social, economic, and political systems. There is a distinct language, culture, or belief system. And there is self-identification as different from the mainstream national society.

Of these, self-identification has become the closest thing to a universal anchor. Most contemporary working definitions, including the criteria used in the Draft UN Resolution on Indigenous Rights, treat self-identification as the primary test, with the other four threads serving as supporting evidence rather than strict requirements.

Why many communities reject definitions imposed from outside 🔗

It is worth pausing on why indigenous communities themselves have often resisted being defined by external agencies. Many groups carry a long history of forced assimilation, land dispossession, and policies designed by colonial or national governments without their input. Being defined by outsiders, even well-meaning ones, can feel like a continuation of that pattern rather than a break from it. This is precisely why the 1986 self-identification clause and the ILO’s “fundamental criterion” language matter so much in practice: they shift authority over identity back to the communities themselves.

This tension also plays out in terminology. The World Bank’s policy notes that the communities it protects are known by different names in different countries, including indigenous ethnic minorities, aboriginals, hill tribes, minority nationalities, scheduled tribes, or tribal groups. In India, the constitutional term is Scheduled Tribes, a category defined under Article 342 and administered through the Ministry of Tribal Affairs. Indian policy generally uses “Scheduled Tribes” rather than “indigenous peoples,” partly because the government has historically taken the position that most of India’s population descends from ancient migrations, making a strict distinction between “indigenous” and “non-indigenous” groups difficult to apply domestically. Even so, most of the communities the world calls indigenous, and India calls Scheduled Tribes, satisfy the same underlying criteria found in the Cobo, ILO, and World Bank frameworks: historical continuity, distinct institutions, and a strong claim to self-identification.

Why the absence of one definition is not a failure 🔗

Students sometimes assume that the lack of a single legal definition reflects confusion or indecision on the part of international bodies. It is more accurate to see it as a considered response to genuine diversity. A rigid, universal definition would inevitably exclude legitimate communities whose history or circumstances do not fit a narrow template. The working-definition approach, imperfect as it is, allows the ILO, the UN, and the World Bank to apply protections flexibly across radically different national and cultural contexts, from the Amazon basin to the hill tracts of northeast India.

What do you think? Given that self-identification now sits at the centre of almost every definition, should governments have any role at all in deciding who counts as indigenous, or should that decision rest entirely with the communities themselves? And does India’s continued use of “Scheduled Tribes” instead of “indigenous peoples” change how protections are applied in practice, or is it mostly a matter of terminology?
