Özet: Since the 20th century, cities have been accepted to have a chaotic structure consisting of many subsystems related to political, social, economic life, and space. This chaotic structure that repeats itself independently of scale has a fractal geometry. Developments in the field of geographic information systems in the last 30 years have provided great conveniences in examining this structure of cities with fractal dimension analysis. The geometrical shapes of buildings, streets, and blocks that create the physical city form constitute at the same time the fractal urban geometry. The study aims to determine the complexity level of the city by calculating the fractal urban geometry. The fractal dimension values of the buildings, roads and zoning blocks were calculated and the geographical distribution of these values were examined by statistical methods. In this context, the fractal dimension values of fractal urban geometry components were calculated separately in the study area consisting of 65 neighborhoods in Sivas province, central distirict. A two-step cluster analysis was used to determine how these obtained fractal values dispersed geographically within the study area. According to the results, neighborhoods with high level of complexity constitute 71% of the study area.
