THE 2015 UPDATE: A RE-SHAPED HUMAN, SOCIAL AND ECONOMIC GEOGRAPHY
The 2015 Update identifies 1 947 urban agglomerations as of 2010 and the data allows to characterise and track the evolution and territorial transformation of old and new urban centres (population, location, distances between agglomerations, and morphology).
The data highlight the importance of small- and medium-sized agglomerations in national urban networks and the emergence of new urban agglomerations through in situ urbanisation.
The SWAC Secretariat worked with the e-Geopolis Project on the 2015 update of Africapolis which covers 17 West African countries spanning the period 1950 to 2010.
The Update provides:
- Systematic geolocation of urban agglomerations (with at least 10,000 inhabitants and less than 200 metres between buildings) broadening the analytical scope for mapping and spatial analysis;
- The identification of small cities (fewer than 100 000 inhabitants) that are not listed in any international database and which count for 90% of West Africa’s cities, or a combined population of 45 million people;
- Extensive and updated inventory of agglomerations in Nigeria, accounting for more than half of West Africa’s population.
