| Summary: | The urban areas in Algeria suffer from several imbalances in different regions, where the inequality of opportunities has led to an imbalance in the population density “from north to south”. And to the urban chaos, this matter made it face many challenges, which prompted us to search for this defect. Development plans in Algeria focus on the role of cities with high hills in restoring balance to the national sphere and reducing these disparities. The study aims to extract and evaluate the spatial differences of the three cities and reveal the spatial disparities, in order to establish a balanced regional development, while preparing the various development plans, based on several criteria by integrating the Delphi method with the analytical hierarchy process, and determining its spatial regions in the (GIS) environment. Through a comparative study of three cities, the study showed the progress of the city of Setif, achieving (11%) of the study area, achieving high quality, with an area (14.50 km²), Al-M’sila (03%) with an area (7.99 km²). Barika (01%) with an area of (3.98 km2). The results can be used during the preparation of development plans for this region.
