The Relationship Between Wealth Disparity and the Sex Ratio at Birth

This work delves into the complex interplay between the wealth gap, son preference, and sex ratio at birth (SRB) imbalance. Although the natural sex ratio is around 105 to 100, imbalances in some regions that exceed this range are associated with a preference for boys, which has cultural and economic roots. This paper examines the link between wealth inequality and SRB and finds that the relationship is not direct. Global and Chinese data analysis shows no direct relationship between GDPs per capita and SRB in different countries, nor is there a one-to-one correspondence between GDPs per capita and SRB in other provinces in China. The study found that the family planning policy and unregistered women after birth also contributed to the gender gap. Contrary to assumptions, the study shows no significant relationship between wealth gaps and skewed SRBS, underscoring the multifaceted nature of this issue.
