[[Demography|Demographic]] features of the [[population]] of the [[Republic of the Congo]] include [[population density]], [[Ethnic group|ethnicity]], education level, health of the populace, economic status, [[Religion in the Republic of the Congo | religious affiliations]] and other aspects of the population.

The Republic of the Congo's sparse population is concentrated in the southwestern portion of the country, leaving the vast areas of tropical [[jungle]] in the north virtually uninhabited. Thus, Congo is one of the most urbanized countries in Africa, with 85% of its total population living in a few urban areas, namely in [[Brazzaville]], [[Pointe-Noire]], or one of the small cities or villages lining the {{convert|332|mi|km|order=flip|adj=on}} [[Congo-Ocean Railway|railway which connects the two cities]]. In rural areas, industrial and commercial activity has declined rapidly in recent years, leaving rural economies dependent on the government for support and subsistence. Before the [[Republic of the Congo Civil War (1997–1999)|1997 civil war]], about 15,000 Europeans and other non-Africans lived in Congo, most of whom were French. Presently, only about 9,500 remain. [[Pygmies]] make up 2% of Congo's population.<ref>{{cite news|url=http://www.lemonde.fr/afrique/article/2011/08/05/les-pygmees-du-congo-en-danger-d-extinction_1556735_3212.html|title=Les pygmées du Congo en "danger d'extinction"|newspaper=Le Monde.fr|date=5 August 2011|via=Le Monde}}</ref>
