The impact of Mehr housing on population growth and immigration of cities of Iran

The Mehr housing is a special experience in the direct intervention of governments on a large scale, which instead of focusing only on big cities and metropolises, has entered different levels of the urban network, and it is different from similar programs in different countries of the world. The positive and negative residential, spatial, social, economic and programmatic characteristics of Mehr housing affected the direction and destination of migrations in the urban network, so that with the increase in the ratio of built of Mehr housing to the existing households in the cities of the country, increased the rate of population growth and finally immigration. This subject forms the hypothesis of the current research. The research method of the article is descriptive-analytical and its purpose is theoretical and practical. Statistics were collected through library and documentary methods and studies at two different levels including 31 provinces and urban sampling (40 cities in different provinces. The relationship between research variables measured through Pearson's correlation coefficient, kernel density and spatial weighted regression and its findings confirmed the research hypothesis. The results of the research show that the increase in the building of low-cost housing in cities has led to an increase in population growth and ultimately their immigration, and small and medium-sized cities have accepted the largest population impact within the urban network. The suggestions of the article also include empowerment, dispersion and native development.
