District Level Estimation of Life Expectancy in Iran

Life expectancy (at birth) is an estimate of the number of years a baby born in a certain year will expected to live, based on the mortality rates measured in that year. Demographers use the symbol e00 for life expectancy at birth (age 0). However, the index is heavily influenced by the rate of infant mortality. The main objectives of the paper are to estimate life expectancy for sub provinces population using IMR only.
Secondary data were used for the study. This study is to estimate the life expectancy of sub population. IMR is available for combined, males and females separately.
To estimate the life expectancy regression models were used. We have to fit a regression equation. With the help of this observed life expectancy and infant mortality rate we fit a regression equation. The regression equation is e00: a + (b*IMR) + (c*IMR2).
We used the estimated IMR values for the major provinces for 2010. According to data Esfahan, females had high IMR , Kordestan and Sistan Baloghestan have the lowest life expectancy. Razavi khorasan and Esfahan had high IMR. Golestan had the least difference for the combined and females life expectancy, but for males the least values are in Khozestan and Semnan. The T- Test was also applied and the values are significant.
