The 2010 census estimated the population as 8,032,551 which makes South Sulawesi the most populous province on the island (46% of the population of Sulawesi is in South Sulawesi), and the sixth most populous province in Indonesia. By mid 2019 this was estimated to have risen to 8,851,200. The main ethnic groups in South Sulawesi are the Buginese, Makassarese, Toraja, and Mandar. The economy of the province is based on agriculture, fishing, and mining of gold, magnesium, iron and other metals. The pinisi, a traditional Indonesian two-masted sailing ship, is still used widely by the Buginese and Makassarese, mostly for inter-insular transportation, cargo, and fishing purposes within the Indonesian archipelago.
