Worry about old-age support: Chinese rural bachelors' perspective

China's gender imbalance has led to severe bachelorhood for decades. The purpose of this study was to examine the association between potential availability of family support and worry about old-age support for themselves and their parents from the perspective of rural bachelors. Data was drawn from a cross-sectional survey "Mobility, Sexuality, and Quality of Life of Never Married Men in Rural China", which was conducted in 9 provinces in 2017. The sample included 359 men who were at least 28 years old, have rural household registration (hukou, in Chinese), and never married. Logistic regressions were used to examine the association between potential availability of family support, measured by living parents and siblings, and worry about old-age support. Results showed that rural bachelors who had a sister(s) were less likely to worry about both their own and their parents' old-age support than those without sister(s) (OR = 0.496, p < 0.01; OR = 0.494, p < 0.01). Bachelors with a non-bachelor brother(s) were less likely to worry about their parents' old-age support than those without brother(s) (OR = 0.436, p < 0.01). Our findings highlight the importance of potential availability of family support in determining worries about old-age support for bachelors and their parents. Considering the low level of social security in rural China and the rapid increase in the number of aging bachelors, policies that compensate for the lack of family support should be implemented to relieve vulnerable bachelors' worries.
