Improving the vitality of a city can not only make people satisfied with the aspects of green ecology, economic development, cultural creativity and quality of life, but also helps to promote its sustainable development. Today, however, cities have rapidly undergone spatial changes under the pressures of modernity. These developments have caused social and economic imbalances. As the largest city in the country with diverse economic, social, physical and cultural functions, Tehran is experiencing complex problems, which has led to the reduction of its vitality. Therefore, the current research was conducted with the aim of evaluating the living conditions in the neighborhoods of Tehran. The data to measure the vitality were extracted from the statistical blocks of the statistics center, land use map of the city, and satellite images. To evaluate vitality, several main components including economy, demographics, tourism, quality of life, air quality, and nightlife were used as indicators. The results of the research showed that vitality in Tehran can be summarized into four main factors. The first factor with 19% of the total variance had the highest impact, and the fourth factor with 10% of the total variance had the least impact in the vitality category. In total, by combining the four factors of vitality in Tehran, the final map of vitality was produced. The combined vitality map showed that the central and northwestern parts of the city have good conditions in terms of urban vitality, but the southern and southeastern parts of the city are in unfavorable conditions in this regard. Also, the results indicated that, as one moves away from the central part of the city, the level of vitality gradually decreases.
