Abstract Urban vitality is one of the key indicators of the quality of public spaces and plays a decisive role in enhancing social interactions, dynamism of activities, and citizens’ sense of place attachment. However, vitality is not evenly distributed across the city and is influenced by the spatial structure, accessibility, and locational characteristics of public spaces. The aim of this study is to analyze the spatial pattern of urban vitality in the public spaces of Tabriz and to identify its distribution and concentration using spatial data. The research adopts a descriptive–analytical methodology with a quantitative approach based on spatial analysis. The required data were obtained from statistical sources, urban spatial layers, and information related to public spaces. To measure urban vitality, a set of physical, functional, and accessibility indicators was selected and, after standardization, analyzed within a Geographic Information System (GIS) environment. Spatial pattern analysis and zoning techniques were employed to identify areas with high and low levels of vitality.The findings indicate that urban vitality in Tabriz exhibits an uneven spatial pattern, such that public spaces located in central areas with better accessibility demonstrate higher levels of vitality, while peripheral and underserved areas experience lower vitality. The results of the analyses suggest that factors such as activity density, spatial connectivity, and accessibility play a significant role in shaping this pattern. In conclusion, spatial analysis of urban vitality proves to be an effective tool for identifying spatial inequalities and guiding urban planning toward improving the quality of public spaces. The findings of this study can provide a basis for urban managers’ decision-making aimed at achieving a more balanced distribution of facilities and strengthening urban vitality throughout the city of Tabriz.
