A recent study published in Acta Psychologica explored how the number and gender of children influence parental happiness in modern China. Researchers analyzed data from the Chinese General Social Survey (CGSS), which collected responses from over 49,000 people between 2012 and 2021. The study focused on how parents' happiness is affected by whether they have sons, daughters, or a mix of both. The findings suggest that parents with only daughters tend to report higher levels of happiness compared to those with only sons. The researchers used a standard happiness measurement, asking participants to rate their overall life satisfaction on a five-point scale ranging from "very unhappy" to "very happy." They then categorized families based on the number and gender of their children. The results showed that parents with two daughters reported greater happiness than those with two sons. However, having one son and one daughter did not significantly increase happiness compared to having two sons. The strongest link between having daughters and increased happiness was found among middle-aged parents, specifically those aged 45 to 59, and especially in rural areas. Researchers suggest that this could be due to cultural and economic factors. For example, young men in China often move to cities for work, which may reduce their contact with their parents. In contrast, daughters may stay closer to their families, maintaining regular emotional and social connections with their parents. The study challenges the traditional belief that sons bring more happiness to parents than daughters. However, the researchers caution that their findings only show a correlation, not a direct cause-and-effect relationship. They emphasize that more research is needed before using these results to inform policy decisions.
