        <label>Abstract</label>
        <p>The development of large cities has a significant influence on surrounding settlements. Urban areas are characterized by diversity and variability, depending on their size, function, combination of elements, and the spatial distribution of industrial and transport infrastructure. Over the past decade, due to population resettlement, urban settlements have undergone substantial transformations. However, spontaneous processes often accompany urban development, and land use efficiency remains suboptimal. The relevance of this study is determined by the necessity of analyzing urban territories as an integral part of the city. This paper presents an analysis of the structure and dynamics of suburban development in the vicinity of Aktobe. The expansion of these areas plays a crucial role in shaping the city’s economic landscape and determining its growth trajectories. The study employs statistical, comparative-analytical, and isochrone methods. From a geodemographic perspective, the suburban zone of Aktobe is of particular interest due to its formation characteristics and specific spatial dimensions. The most active and attractive development occurs within a 15–30 km radius from the city center, corresponding to 40-minute and 90-minute isochrones. In recent years, Aktobe has been experiencing rapid urban growth, necessitating the resolution of key planning issues such as functional zoning, urban regulation, development of major transport infrastructure, preservation of recreational areas, and the establishment of green spaces. A SWOT analysis of the settlements surrounding Aktobe was conducted as part of the study. One of the identified strengths is the favorable transport and logistics situation. Additionally, the study evaluates other strengths and weaknesses, as well as potential opportunities and existing constraints for suburban development.</p>
