Mobility network approaches for studying neighborhood inequality and change.

Research on neighborhood inequality increasingly emphasizes the need to move beyond residential-based frameworks by considering the neighborhood environments individuals visit beyond their homes. This talk examines how citywide mobility networks-structural connections within cities formed by residents' routine travels between neighborhoods-offer new insights into neighborhood inequality and change. Using examples at both individual and aggregate levels, I show how mobility-based disadvantage predicts child health independently of residential factors and how segregated mobility patterns influence the likelihood of neighborhood socioeconomic ascent. These findings highlight the importance of studying structural and spatial dynamics beyond residential boundaries to fully understand neighborhood inequality and change.
