Isolated indigenous groups avoid contact with modern society

There are an estimated 196 indigenous groups worldwide living in voluntary isolation or avoiding contact with modern society. These communities are primarily located across approximately ten countries in South America, Asia, and the Pacific, including Brazil, India, and Indonesia.

These groups live in diverse environments such as dense tropical forests, isolated islands, and deserts. While some experience sporadic contact due to the encroachment of oil, logging, mining, and agricultural industries, others actively work to avoid external influence to preserve their unique ways of life.

A prominent example is the Sentinelese people, who inhabit North Sentinel Island in India’s Andaman and Nicobar archipelago. Believed to be direct descendants of the first human populations to leave Africa roughly 55,000 years ago, the community likely numbers between 50 and 150 individuals. They rely on fishing, hunting, and gathering, and have historically responded to approaching vessels or aircraft with arrows to signal their desire to remain undisturbed. To protect the community from external diseases and ensure visitor safety, India has prohibited access within a five-kilometer radius of the island.
