Saint Helena is the most populous part of Saint Helena, Ascension and Tristan da Cunha. The language spoken in Saint Helena is English.

The island has a small population of a few thousand inhabitants, mainly descended from Africans, Mixed race African and Europeans, British settlers, East India Company employees and indentured labourers from the South Asian sub-Continent, East Indies, Madagascar and China.[1]

The people of Saint Helena are Saint Helenians (though locally they are known as "Saints"); the demonym being Saint Helenian.

The fall between 1998 and 2008 can be explained mostly by emigration, especially since 2002 when the islanders were granted full British citizenship.

The population density, based on the 2016 figure, is 37.3 persons per km2, or 95.3 per sq mile.
