WhenSaint Helena was discovered in the 16th century the island was uninhabited. With almost 10,000 inhabitants at the 1901 census, the highest number of residents was reached. However, this number included almost 6,000 Boer prisoners of war.[1] Excluding the prisoners of war (who were on the island during 1900-1902), the highest population in the twentieth century was reached in 1987. The population gradually decreased thereafter and reached 4,000 in 2024,[2] mainly descended fromAfricans,Mixed race African and Europeans, British settlers,East India Company employees and indentured labourers from theSouth Asian sub-Continent,East Indies,Madagascar and China.[3]
The language spoken in Saint Helena is English.
The people of Saint Helena areSaint Helenians (though locally they are known as "Saints"); thedemonym beingSaint Helenian.
Acensus in February 2016 recorded a population of 4,534 on the island.[4] This compares with a figure of 4,257 recorded in 2008[5] and a figure of 5,157 recorded in 1998. The fall between 1998 and 2008 can be explained mostly by emigration, especially since 2002 when the islanders were granted full British citizenship. The maindiasporas are to the United Kingdom, South Africa and more recently to theFalkland Islands, as well as onAscension Island. The population density, based on the 2016 figure, is 37.3 persons per km2, or 95.3 per sq mile.
The island of Saint Helena is administratively divided into eight districts,[6] each with a community centre. The districts also serve as statistical subdivisions. The island is a single electoral area, sending twelve representatives to theLegislative Council.
