In this study, we examined the effects of development on the relationship between fertility and female labor supply. Methods: We used data of population and housing census of Iran and estimated three separate models. To do this we employed Logistic Regressions (BLR). Results: The estimation results of our study showed that there was a negative relationship between fertility rate and female labor supply and there are some differences for this relationship in three models. Conclusion: When fertility rate increases, FLS would decreases. In addition, for higher fertility rates, the woman might be forced to work more because of the economic conditions of her family; and negative coefficients of the fertility rate effects on FLS would increase with a diminishing rate.   https://ijph.tums.ac.ir/index.php/ijph/article/view/6103 https://ijph.tums.ac.ir/index.php/ijph/article/download/6103/5301
