T Futurology of Iran's Demographic Changes from 1390 to 1420 (2011- 2041)

The present paper investigates the futurology of Iran's population, in which a demographic-documentary analysis is used as its method. The most recent demographic predictions (2012) for world's countries, made by United Nations Population Division, indicate that Iran's population, according to three scenarios of UN (lower level, medium level and higher level), will reach to 87.7, 96.8 and 106 million people, respectively. According to the adjusted scenario which is proposed by the authors of this paper, Iran's population will reach to 91 million people in 1420 (2041).The received results indicate that under replacement level fertility (less than 2.1 infants born alive for each mother) will continue in Iran, which highlights the necessity of futuristic planning for managing seniority in the country. Improvement and reinforcement of family foundation and promotion of religious and Islamic values which are mostly family-based can help to promote the level of fertility and amend the age pyramid of population.
