rural-urban migrations

Iranian formal censuses indicate that the share of rural population in total population of Iran have been decreasing over the time and many villages are uninhabited. Migration statistics in Iran have also indicated intense migration from villages to the cities during the past half- century. Many researches have been conducted due to the importance of rural-urban migrations, during the past few years. Therefore, the main goals of this study are to criticize and evaluate the written articles using meta-analysis method in rural-urban migrations field and to identify the most important factors affecting rural-urban migrations, widely used theoretical approaches in this area and etc. The findings of this research show that attraction and repulsion viewpoint and Michael Todaro&rsquos theory are appropriate theoretical approaches to state the problem of rural-urban migrations in Iran. Also, urban attraction variables with impact size of 0.75 and occupation with impact size of 0.62 have the most effect on rural-urban migration. Other findings indicate that the most solutions proposed in the reviewed researches are general, vague and non-executive and there is no proportionality between the proposed solutions and the study objectives in most cases.
