The development of urbanization and urbanism in Iran has created a wide socioeconomic gap in urban areas. Rapid population growth along with the lack of socioeconomic growth programs and urban development strategies have deteriorated unemployment, inflation, housing price, traffic congestion, and marginalization in cities, particularly in metropolises of Iran. This paper, using a descriptive-analytic research method and a meta-analysis technique, addresses the urbanization and urbanism changes in Iran. Using GIS technique and CV formula, the spatial distribution of urbanization and its rapid growth in Iran are depicted. The research data was derived from a systematic review of documents and techniques over 40 years. The results of the study demonstrated that Iranian cities have undergone an unsustainable growth trend and urbanization has overtaken urbanism. Over the past 4 decades, cities have been struggling with rapid growth and development. In this regard, development-oriented governments can play a significant role in tackling growth and urbanization problems. These problems are especially evident in the socio-economic, urban planning and urban ecology. The rapid growth of urbanization (74% in 2016) has resulted in the emergence of metropolitan areas in an unstable process. Also, in metropolitan areas of Iran, environmental and ecological threats, rural–urban migration and marginalization have posed serious national–regional and local challenges. The structural–functional reforms in Iran, along with skeletal–spatial and socio-economic changes in cities, have given rise to a new social class (low-income people), which is characterized with non-formal businesses and informal settlements in the outskirts of cities, especially metropolitan areas. This has prompted unsustainability in main indicators of urban development such as security, building density, environmental threats, and centralization, among other things. This analysis is based on indicators such as density and centralization, informal settlement, and urban security.

伊朗城市化和城市化的发展在城市地区造成了巨大的社会经济差距。人口的快速增长，加上缺乏社会经济增长计划和城市发展战略，加剧了失业率，通货膨胀，房价，交通拥堵和城市边缘化，特别是在伊朗大都市。本文采用描述性分析研究方法和荟萃分析技术，探讨了伊朗的城市化和城市化变化。利用GIS技术和CV公式，描述了伊朗城市化的空间分布及其快速增长。研究数据来自40多年来对文件和技术的系统回顾。研究结果表明，伊朗城市经历了不可持续的增长趋势，城市化已经超过了城市化。在过去的40年中，城市一直在努力快速发展。在这方面，以发展为导向的政府可以在解决增长和城市化问题方面发挥重要作用。这些问题在社会经济，城市规划和城市生态学中尤为明显。城市化的快速增长（2016年为74％）导致大都市地区出现了不稳定的过程。同样，在伊朗大都市地区，环境和生态威胁，农村向城市的迁徙和边缘化构成了严重的国家，地区和地方挑战。伊朗的结构功能改革以及城市的骨架，空间和社会经济变化，已经引起了新的社会阶层（低收入人群），其特征是城市郊区，特别是大都市地区的非正规企业和非正式住区。这导致了城市发展的主要指标（例如安全性，建筑密度，环境威胁和集中化）中的不可持续性。该分析基于密度和集中度，非正式住区和城市安全性等指标。
