Earth’s Hidden Peoples: The World’s Least-Contacted Communities
An estimated 196 uncontacted or voluntarily isolated Indigenous groups survive in roughly 10 countries, from the Sentinelese on North Sentinel Island to groups in the Amazon like the Kawahiva and Mashco Piro. Definitions of “uncontacted” vary, and some communities erase footprints to stay hidden, while others have historically suffered harmful contact. The debate centers on whether to pursue protective contact or to respect autonomy, grounded in Indigenous rights to self-determination and safety.
