The research dealt with the application of the spatial spread analysis of the slums housing areas in the city of Zagazig using geographic information systems, and the spatial distribution pattern of the slums and the regions were classified in terms of the area into (large, medium, and small). And it determined the spatial spread of these areas: the central area of the city with a radius of 1.5 km, the next area on the borders of the urban boundary with a distance of about 1.5: 3 km, and the area outside the urban boundaries, including Shaybah and Nakaria, about 3: 4.5 km. The results of the research revealed that small slum areas are the most prevalent in the central region, representing \(61.54\%\) and an area of \(13.22\%\), but large areas represent a total area of \(49.11\%\) and therefore small areas can be removed and large areas developed.
