13,068,161 people (2010 est.) live in Angola, and like most other African countries the population is very young, with a median age of 18.  The population is divided into three main ethnic groups: the Ovimbundu in the central highlands (37%), the Mbundu along the coastal plain and around the capital city Luanda (25%), and the Bakongo people of northern Angola (13%), who are also a prominent group in neighboring Congo-Brazzaville and the Democratic Republic of the Congo.  Other African ethnic groups, Europeans, and people of mixed European and African descent (mesticos) make up the rest of the population.
