Urbanization in Algeria: Toward a More Balanced and Sustainable Urban Network?

Before colonization, Algeria was primarily a rural country with a nomadic and semi-nomadic population. However, significant changes occurred during and after the colonial era as modernization efforts were implemented. This paper provides a regional overview of Algeria’s pre-and post-millennium urban development based on census population data expressing the quantitative side of urbanization. Our analysis focuses on three aspects: regional structural tendencies of urbanization, sources of urban growth, and the current state of Algeria’s urban network. We contextualize our findings by comparing them with the existing literature and the priorities outlined in the country’s National Spatial Development Plan 2025. Our research suggests that: (1) First-stage (concentration) and second-stage (suburbanization) urbanization features, as well as internally and externally determined development, characterize Algeria’s urban network. (2) A decreasing and regionally differentiated urban growth rate indicating a moderate shift towards non-coastal regions and the above-average dynamics of large cities and smaller towns can be observed. (3) The significance of natural growth as a source of urbanization is higher than the contributions of rural-urban migration and new “de jure” towns. However, these factors are differentiated among the regions, highlighting the secondary role of rural-urban migration in the internal peripheries and the importance of new “de jure” towns in the densely populated and urbanized northern regions. (4) Algeria’s urban network is divided into three sharply differentiated zones that have experienced only moderate changes. We regard this shift toward a spatially more balanced urban network as a factor supporting but not guaranteeing sustainable development.
