Understanding the consequences of mother age at first birth on the outcomes of kids becomes more important as the rate of maternal age at first birth continues to climb in industrialised countries. Using data from the Indian administrative register that covers birth cohorts from 2018 to 2020, this research analyses the complex link that exists between the age of the mother and a variety of life outcomes. By using fixed-effects regression models, we are able to separate individual-level impacts from changing period circumstances associated with birth cohorts. Our primary areas of focus include educational achievement, physical fitness, and height. According to the findings of our study, there is a fascinating inverse U-shaped connection between maternal age and outcomes. Children who were born to moms who were either the youngest or the oldest had lower rates of achievement. By the by, when the ideal impacts of being brought into the world in a later birth companion is thought about, the general impact of expanding mother age shows up as ceaselessly certain. In contrast to the prevalent worries, fully adjusted models demonstrate that there are no significant disadvantages for people who were born to moms who were older when they reached maturity. The implications of these results call for a reassessment of the discussion around delayed motherhood. They offer light on possible advantages that go beyond considerations at the individual level and involve wider social trends.
