Rural migration crisis is one of the most challenging problems in the socio-economic space of Iran. In this study, the fuzzy approach is applied to examine the effects of some variables like poverty, rural unemployment rate, the rural Gini coefficient, urban to rural wage ratio, drought situation and literacy rate on migration. In order to find the appropriate model, the Tanaka and FLSR fuzzy regression approaches are compared. The effects of the socio-economic variables on rural migration in Iran are examined during the period 1990-2018
