Saint Helena, Ascension, and Tristan da Cunha Population

Saint Helena, Ascension, and Tristan da Cunha, a British Overseas Territory in the South Atlantic Ocean, have experienced slow and fluctuating population growth due to their isolated locations and limited economic opportunities. Saint Helena, the largest and most populous island, has seen its population decline from a peak of over 5,000 in the mid-20th century to around 4,400 in recent years, as many residents have emigrated for work, particularly to the United Kingdom. Ascension Island and Tristan da Cunha have even smaller populations, with Ascension hosting a transient community of around 800 mainly military and contract workers, and Tristan da Cunha, known as the world’s most remote inhabited island, home to fewer than 250 permanent residents. Overall, the territory’s population growth remains minimal, shaped by migration patterns, employment opportunities, and the challenges of remote island living.
