Filial piety—the belief that children should provide care, support, respect, and obedience to their older parents—is a fundamental normative expectation in East Asian societies. This study investigates the relationship between the geographic proximity of children and the support received from them, and their parents’ perceptions of filial piety in rural China.

We used the 2021 wave of the Longitudinal Study of Older Adults in Anhui Province to predict parental assessments of filial piety for each of their children. Random-effects linear probability models using an internal moderator approach were employed to compare coresident children with non-coresident children based on their proximity and support provided.

Findings indicate that parents tend to perceive their coresident children as being more filial compared to non-coresident children, particularly when parents are in worse functional health. However, non-coresident children can compensate for their deficiency in being perceived as filial by providing more financial support and maintaining frequent telephone communication with their parents.

The study's results suggest that filial piety norms in rural China have adapted to the diminished emphasis on intergenerational coresidence resulting from the trends of urbanization and significant rural–urban migration in modern China, requiring that children find alternative ways to fulfill their filial obligations.
