In this study, households’ incomeexpenditure raw data published by the Statistical Center of Iran was used. The results show that the incidence and intensity and MPI are decreased in this period of study. The most incidence and intensity of poverty belongs to 1989. Also, the poverty incidence of rural areas is more than in urban areas in 1989, 1994, 1999, 2004, and 2014, but intensity of poverty in rural areas is more than urban areas in all years.
