Demography of Elder Population in Iran Over the Period 1956 to 2006

age group. This study aims to assess the trend and changes in sex ratio, average annual growth rate, ageing index and dependency ratio of the elderly population by documen­tary method during the period 1956 through 2006 using Iranʹs Population and housing census data that collected by Statistical Centre of Iran. According to our findings, the estimates of some basic demographic in­dices such as the proportion, sex ratio, average annual growth rate, age­ing index and dependency ratio for the iranian elderly population at 2006 were 7/3%, 108, 2/5%, 29 and 43/4%, respectively. Considering the rapid decline in fertility during the last two decades, it is anticipated that ageing process will accelerate. This process is documented by observed trend of fertility and mortality rate and their possible changes in the future. Con­sidering the facts, figures and findings of this study iran is going to experi­ence an increasing proportion of elder population by the beginning of the next solar century
