Is late childbirth advantageous to the offspring’s development?
【Abstract】In the process of industrialization, the marriage and childbirth ages are generally postponed. This trend is also increasingly significant in China. Examining the persistent influence of parents’ childbearing age on their offspring’s development has become a global research project. According to most studies, for the offspring whose parents’ childbearing age is late, their development is more advantaged, but the relevant assessment based on Chinese context still needs to be filled. Using the data from China Education Panel Survey, this paper systematically tests the relationship between them and has the following findings. Regarding most indicators, there is a clear inverse U-shaped curve relationship between the parents’ childbearing age and the offspring’s development condition in adolescence. For the offspring whose parents conceived them among 26–29 years old, they have the best development in multiple aspects (especially educational achievement) in adolescence; while for the offspring whose parents conceived them too early or too late, they are more likely to be disadvantaged in development environment and achievement. Several factors could partly explain the above disadvantaged situations, including offspring composition, parents’ social-economic status and family environment.

. (1) The data are based on the sixth census in 2010. The census data also provide the childbearing ages of parents in different childbirth orders. In 2010, the average age when the married women aged 15–49 give birth to the first child is 25.94 years old, that when they give birth to the second child is 30.44 years old, and that when they give birth to the third child or more is 33.22 years old. While the data in the fifth census are: 24.33 years old, 28.56 years old and 30.44 years old. The data in the fourth census in 1990 is: 22.64 years old, 25.44 years old and 29.33 years old. It can be seen that the childbearing age of each child is generally moving backward. [^Back]
