Antofagasta (Spanish pronunciation: [antofaˈɣasta] (listen)) is a port city in northern Chile, about 1,100 kilometres (700 mi) north of Santiago. It is the capital of Antofagasta Province and Antofagasta Region.
According to the 2015 census, the city has a population of 402,669. Previously part of Bolivia, Antofagasta was captured by Chile in the War of the Pacific (1879–83), and sovereignty was transferred under the terms of the 1904 Treaty of Peace and Friendship between the two countries. The city of Antofagasta is closely linked to mining activity, being a major mining area of the country. The last decade has seen a steady growth in the areas of construction, retail, hotel accommodations, population growth, and remarkable skyline development. Antofagasta has the highest GDP per capita of Chile, US$47,000 and the 3rd place for Human Development Index just after Metropolitana de Santiago Region and Magallanes and Antártica Chilena Region. Currently there are several theories to explain the origin of the name Antofagasta. A clear consensus regarding the true origin of the word has not yet been determined. It is probably a compound word that comes from the southern Cacan "anto" (or "hattun", which means "Grande" –big-), "faya" (or "haya", which means "salar"–dry lake-) and "gasta" (meaning "pueblo"), being a toponymy meaning "Pueblo del Salar Grande" ("Town of the great salt lake").
