Demographic features of the population of the Republic of the Congo include population density, ethnicity, education level, health of the populace, economic status, 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 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 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.
