Identifying the structure of social classes and how to change it can be helpful in explaining many social and economic issues. The present study compares the structure of social classes in Iran during the years 1956 to 2016. In this study, the secondary analysis method has been used. The results show that the upper class has been almost constant during these years and the traditional middle class has had almost a larger share than other classes, the new and lower middle classes have the most fluctuations during the years under study. Observing the trend of class structure in different historical periods in Iran shows that political, economic and international factors are the determinants of changes and fluctuations in the structure of social classes in Iran and these effects have been more on the middle and lower class.
