Angola is a west-coast country of south-central Africa. It is the seventh-largest country in Africa, bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. Angola has an exclave province, the province of Cabinda that borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and largest city of Angola is Luanda. Although inhabited since the Paleolithic Era, what is now Angola was molded by Portuguese colonisation. Angola has vast mineral and petroleum reserves, and its economy is among the fastest-growing in the world, especially since the end of the civil war; however, the standard of living remains low for most of the population, and life expectancy in Angola is among the lowest in the world, while infant mortality is among the highest.
