Segregation is a key challenge in promoting more diverse and inclusive cities. Research based on smartphone data has revealed that segregation can extend beyond residential areas into everyday activities like visiting shops and restaurants. The impact of these activities on segregation, however, is unclear. Some studies suggest that they promote mixing, while others indicate they reinforce segregation. Here, we elucidate how day-to-day mobility shapes overall segregation levels, looking at the distinctive segregation experienced by native and foreign-born individuals. Our study is based on ~320,000 smartphone trajectories collected in Sweden, where immigration creates profound divides. We find that while mobility levels generally promote mixing for native-born individuals, foreign-born individuals remain segregated in their out-of-home activities. Using counterfactual simulations, we show that this heterogeneous effect of mobility on experienced segregation results mainly from two mechanisms: homophily and limited travel, i.e., foreign-born individuals (i) prefer destinations visited by similar individuals, and (ii) have limited mobility ranges. We show that homophily plays a minor role, while limited mobility, associated with reduced transport access, limits opportunities for foreign-born to diversify their encounters. Our findings reconcile conflicting literature and suggest that enhancing transport accessibility in foreign-born areas could reduce social segregation. |
