Neighborhood socioeconomic disadvantage and child health: The role of neighborhood mobility networks.

Despite a large body of work on neighborhood effects on health, past studies are limited in their treatment of neighborhoods as largely static spaces with (dis)advantages based primarily on the average characteristics of their residents. In this study, we draw on the triple neighborhood disadvantage perspective to explore how socioeconomic disadvantage in a neighborhood's mobility network uniquely relates to children's overall health levels, independent of residential disadvantage. We investigate this by combining 2019 SafeGraph data on mobility patterns from roughly 40 million U.S. mobile devices with information on children, families, and neighborhoods from the 2015-19 American Community Survey and 2019 Panel Study of Income Dynamics Child Development supplement. We find that mobility-based neighborhood disadvantage (MND) generally predicts child health better than residential neighborhood disadvantage (RND), but associations vary by race and by family income and are contingent on the broader metropolitan context. Our study advances existing research on the effects of mobility networks by shifting from analyzing aggregate-level outcomes to exploring how mobility-based disadvantage affects individual outcomes. Overall, our results indicate that the relationship between neighborhood disadvantage and child health is nuanced and complex. Findings from our study suggest that researchers aiming to understand the influence of neighborhood contexts should examine individuals' residential environments as well as the environments of neighborhoods connected through individuals' everyday mobility.
