This article examines the effect of the increase in the cost of living on the age of marriage in Iran. Age of marriage, reproductive age and number of children are used as dependent variables and income, unemployment and living expenses are used as independent variables in this article. The required data was collected from the distribution of ۳۸۴ questionnaires among single and married men and women. For data analysis, one-sample t-test and Kolmogorov-Smirnov test were used. According to the results obtained from the data analysis, with the increase in the cost of living, the age of marriage and reproductive age also increases, and also with the increase in the cost of living, the desire to have more children decreases, and there is a significant relationship between income and the number of children. This is despite the fact that there is no significant relationship between unemployment and marriage age, if unemployment and income and living expenses are dependent on each other, but in the statistical population of this article, unemployment does not explain its effect on marriage age correctly. Also, there is an inverse relationship between the amount of income and the age of marriage.
