The population of São Tome and Principe is of 187,356 inhabitants (156.84 inhabitants per square kilometer), accor-ding to the 2012 census.

The population of São Tome and Principe is the result of a mixture of descendants of slaves, workers hired in other parts of Africa and European settlers, mainly Portuguese. These groups gave rise to a population with remarkable cultural richness and diversity.
About half of the archipelago’s population lives in the city of São Tome.
