The Inuit are an Indigenous people of the Arctic, living across northern Canada, Greenland, Alaska, and a small part of Russia. They share a common ancestry, a family of closely related languages, and thousands of years of adaptation to one of Earth’s harshest environments. In Canada alone, the 2021 census counted 70,545 Inuit, making them one of the country’s three recognized Indigenous Peoples alongside First Nations and Métis.
Where Inuit Live
Inuit communities stretch across a vast arc of Arctic coastline. In Canada, the Inuit homeland is called Inuit Nunangat, an Inuktitut phrase meaning “the place where Inuit live.” It spans four distinct regions: Nunavut (the largest, covering much of the central and eastern Canadian Arctic), Nunavik in northern Quebec, Nunatsiavut in Labrador, and the Inuvialuit Settlement Region in the Northwest Territories and Yukon.
Outside Canada, Greenland is home to the largest single Inuit population. The Kalaallit, as Greenlandic Inuit are known, make up the majority of the island’s residents. In Alaska, Iñupiat communities live along the North Slope and western coastline. A smaller group, the Yupik, are sometimes discussed alongside the Inuit but are a separate people with their own languages. Across all regions combined, the total Inuit population is roughly 180,000.
Ancestry and the Thule Migration
Modern Inuit descend from the Thule culture, a maritime people who developed along the coasts of Alaska beginning around 1 A.D. The Thule were expert sea mammal hunters, building their lives around whales, seals, and walruses. Around 1,000 years ago, they began a rapid eastward migration, spreading across the entire North American Arctic and reaching Greenland. Archaeologist Therkel Mathiassen first proposed this migration pattern in 1927, and decades of archaeological evidence have confirmed it.
The Thule migration is remarkable for its speed and scale. Within a few centuries, a single cultural tradition had expanded from the Bering Strait to the Atlantic coast of Greenland, a distance of more than 6,000 kilometers. Along the way, the Thule displaced or absorbed earlier Paleo-Eskimo populations. By roughly 1500 A.D., the Thule tradition had given rise to the diverse regional Inuit cultures that exist today.
Language Across the Arctic
Inuit languages form one branch of the Eskimo-Aleut language family. Despite spanning thousands of kilometers, these languages are closely enough related that speakers from neighboring regions can often understand each other, though intelligibility drops with distance. The major groupings include Iñupiaq in Alaska, Inuvialuktun and Inuktitut across Canada, and Kalaallisut (Greenlandic) in Greenland.
Within each of these groupings, further regional dialects exist. Alaskan Iñupiat alone speak three distinct dialects with limited mutual intelligibility. Canadian Inuktitut splits into western variants like Inuinnaqtun and Kivallirmiutut, and eastern variants spoken in Baffin Island and Nunavik. Greenlandic has three main forms: standard Kalaallisut in the west, Tunumiit oraasiat in the east, and Inuktun in the far north around Qaanaaq.
Kalaallisut is the official language of Greenland and the most widely spoken Inuit language. In Canada, Inuktitut has co-official status in Nunavut alongside English and French, and language revitalization programs are active across all four Inuit Nunangat regions.
A Biology Shaped by the Arctic
Living in the Arctic for over a thousand years left a mark not just on Inuit culture but on Inuit genetics. The traditional diet consists almost entirely of marine animals: seal, whale, walrus, and Arctic char. These foods are extremely high in omega-3 fatty acids, a type of fat rarely consumed in such quantities by other populations.
Genetic studies have identified a cluster of genes involved in fat metabolism that show strong signs of natural selection in Greenlandic Inuit. These genes control enzymes that convert dietary fats into the long-chain fatty acids the body needs. In populations eating a typical Western diet, the body relies heavily on these enzymes to build essential fats from plant-based precursors. In the Inuit, where the diet already supplies those fats directly from marine animals, the genetic variants appear to dial down that conversion process. This adaptation also influences height, weight, and other metabolic traits, and likely developed over the roughly 1,000 years the Inuit have inhabited Greenland.
Political Self-Governance
Inuit political organization is notable for its scope. In Canada, the Inuit Tapiriit Kanatami (ITK) serves as the national representational organization, while each of the four Inuit Nunangat regions has its own land claims agreement with the federal government. These agreements are recognized as treaties under Canada’s Constitution, meaning they carry the force of law. Where any federal or territorial law conflicts with these agreements, the agreement prevails.
The creation of Nunavut in 1999 was a landmark in Indigenous self-governance worldwide. It carved a new territory out of the eastern Northwest Territories, giving Inuit a public government covering roughly 2 million square kilometers. Greenland has its own self-governing parliament, Inatsisartut, with authority over most domestic affairs. In Alaska, Inuit communities participate in regional Native corporations established under the 1971 Alaska Native Claims Settlement Act.
Internationally, the Inuit Circumpolar Council represents Inuit from all four countries at forums like the Arctic Council, giving a single people spread across multiple nations a unified political voice on issues from climate change to resource development.
Climate Change and Food Security
No population on Earth faces the consequences of a warming climate more directly than the Inuit. Arctic temperatures are rising two to three times faster than the global average, and the effects on daily life are already severe.
Sea ice is the foundation of traditional Inuit hunting. It serves as a travel platform for reaching marine mammals, a surface for ice fishing, and a habitat for the animals themselves. In Puvirnituq, a community in Nunavik, hunters used to travel on sea ice by late October. Now safe conditions arrive weeks later. In northwest Greenland, the period when dogsled travel on sea ice is possible has shrunk from five months to three.
The animals are disappearing with the ice. Walruses, which depend on ice floes for resting and traveling, have become dramatically harder to find. Hunters across the Arctic report declining marine mammal populations in areas where they were once abundant. This is not just an inconvenience. In remote communities where a gallon of milk can cost over $10 and fresh produce is scarce, traditional food from hunting and fishing remains a nutritional lifeline. Losing access to it means higher rates of food insecurity and greater dependence on expensive, lower-quality imported food.
Health Disparities
Inuit populations face significant health gaps compared to the broader populations of the countries they live in. Life expectancy data, while varying by region, consistently shows the disparity. Greenlandic Inuit men have a life expectancy of about 60 years, compared with roughly 72 for men in comparable northern European countries. Canadian Inuit life expectancy lags the national average by about a decade.
The causes are interconnected: limited healthcare infrastructure in remote communities, high rates of respiratory illness, food insecurity, housing shortages, and the mental health toll of rapid cultural change. Suicide rates among young Inuit men are among the highest in the world. Tuberculosis, largely eliminated in southern Canada, persists in Inuit communities at rates hundreds of times the national average. These disparities reflect decades of colonial policies, including forced relocations and residential schools, whose effects continue to shape health outcomes today.
