In the present study, by examining the literature on the subject, indicators related to Iranian household income were identified, and then by extracting census data from the last 50 years from the Statistics Center of Iran, the trends of changes in these indicators were identified and then using software SMART PLS2 software, the model of the impact of trends related to household income in the country was presented. In this study, structural equation modeling and partial least squares method were used to test the hypotheses and the fit of the model. It shows that Iran's household income in the last 50 years has been affected by changes in agriculture and changes in the capital market, and there is no relationship between energy changes and changes in household income. Based on the obtained data, the population growth trend of Iran has been affected by the trend of income changes. The health index has also been effective on this trend
