Settlement patterns
The country’s four main cultural regions developed from contact and exchange between neighbouring clusters of peoples. The southern region between Brazzaville and the coast is inhabited by the Kongo peoples. Also in the south, the Teke inhabit the Batéké Plateau region. In the north, the Ubangi peoples live in the Congo River basin to the west of Mossaka, while the Binga Pygmies and the Sanga are scattered through the northern basin. Precolonial trade between north and south stimulated both cooperation and competition, while French favouritism toward the peoples of the southwest and postindependence politics intensified ethnic and regional rivalries. Massive internal migration and urbanization since independence have reproduced these cleavages in the cities and towns.
Population distribution within the country is very uneven. The southwestern quarter of the country is home to the majority of the population, while in the north and northeast, population is sparse. In spite of the civil conflict of the late 1990s, which dampened the rate of urbanization, Congo nevertheless remains highly urbanized relative to the sub-Saharan African average, with more than one-half of the population living in cities. Because the urban growth rate far exceeds that of the country as a whole, urbanization continues to intensify. Since this growth has been chiefly the result of internal migration, most rural communities have ties to the larger national community and economy.
The major cities are Brazzaville, Pointe-Noire on the Atlantic coast, Nkayi (formerly Jacob) in the Niari valley, and Loubomo (formerly Dolisie) in the Mayombé region. Colonial creations by and large, the cities reflect French influence: a central administrative and commercial core is surrounded by residential areas. Before independence there was a marked separation between the spacious planned European neighbourhoods and the less-regimented, more populous African parts of town. Since 1960, however, greater social and economic mobility in the African population, attempts at urban renewal, and massive rural-to-urban migration have blurred these distinctions.
