Personal Birth Order Affects Subjective Well-Being—Empirical Analysis Based on CFPS Data

Whether the order of personal birth affects subjective well-being is a question to be tested. This paper uses CFPS2010 data to conduct an empirical study on the relationship between personal birth order and subjective well-being. The main findings of this article are as follows: First, the order of birth (the value from small to large means that the child is born from first to last) has a significantly negative impact on happiness. Second, there is a gender difference in the negative impact of birth order on happiness.
