AbstractDemographic variables play a decisive role in the level of savings. Therefore, the present research, using cross-sectional data and measuring the amount of savings among urban households in Tehran, intends to test its relationship with age transition. The research method is secondary analysis. The investigated data includes the information of 18,610 participating households in the sampling of the expenses and incomes of urban households in Tehran province in 2017 which is done annually by the Iranian Statistics Center and its raw information is provided to researchers. In this research From Dyson's theory of age transition and Modigliani and Endo's life cycle theory used as the theoretical framework of the research. The research findings show that the average percentage of savings among the surveyed middle to low households is 21.80. Also, based on the results of T, F mean difference tests, the average household savings according to the age variables of the head of the household. Gender and activity status are different. Also, the results show that the life cycle theory applies in the urban economy of Tehran and active young population has a more significant savings rate than the two spectrums of children-teenagers and the elderly. Keywords: age transition, household savings, household head age, life cycle Model.

Population growth and changes in age structure both are the most important consequences of demographic transition. how the interaction between these two important variables is resulted from fertility and mortality, and in turn affects national economy is a question which has not been answered in previous researches. Examining the age details of the effect of demographic changes on the economic growth rate, the purpose of this article is to provide an answer to this question. To do this, the population growth rate has been aggregated into age-specific growth rates and using the age profiles of production and consumption, the impacts of the weight and changes of population by age segments on the first demographic dividend have been estimated and analyzed. The findings show that the share growth rate, which indicates both the size and the changes of population of each age, is capable to represent the effect of phenomena such as baby boom, and population momentum on the amount of Iran's demographic dividend. Also, almost simultaneously with the age transition, a demographic-economic transition is taking place due to the interaction of the economic life cycle and the change in the age structure. The results show that the decrease in the population of age groups under 30 years old, during a period from the middle of the first phase to the middle of the third phase of the age transition, makes an important contribution to the negative growth of the effective number of consumers and the increase of the population of prime age adult (30-49 years old) leading to the positive growth of the effective number of producers per consumers and, as a result , the realization of the first demographic dividend in Iran.

According to estimates, more than 5/1 billion Muslims live around the world. Of this population, 45 percent are living in six Muslim countries: Indonesia, Pakistan, Bangladesh, Iran, Turkey and Egypt. Until now, many factors such as levels of development and geographical regions have been considered a basis for the analysis of demographic trends. But it has been less attention to religion as a determinant of age structure changes. The story of demographic transition and its dimensions is essentially based on the pattern of Western Christian societies. Currently, many development experts believe that the development linear models are not efficient enough; hence there should be more attention to the social, cultural similarities and differences between countries and communities. In this paper, according to this assumption that Muslim countries will experience a certain pattern of demographic transition, the age transition will be discussed. In this paper, similarities and differentials of trends and patterns of fertility, mortality and especially age structure are studied in six Muslim countries.
