Social class, intergenerational mobility, and desired number of children in China

With more countries entering an era of low fertility, factors that may shape individuals' childbearing desires have been extensively explored. One's intergenerational social mobility experience, however, remains under-discussed. This paper examines this issue against the backdrop of China, in which the total fertility rate has rapidly declined to the lowest-low level in recent decades. Using pooled five-wave data from the Chinese General Social Survey from 2010 to 2017, we found a checkmark-shaped relationship between social class and fertility desire. Chinese farmers have the greatest desired number of children, manual workers have the lowest, and the two upper classes lie in the middle. In general, one's origin class and destination class play a similar role in shaping fertility desire, demonstrating the coexistence of socialization and acculturation processes. The gender-specific examination further suggests that, compared to women, men are more reluctant to change the fertility attitude learned from the origin class. Based on these findings, our study proposes a novel explanation of the decline in fertility desire in China and contributes to the literature on how social mobility experiences and gender ideology jointly construct fertility desire.
