ABSTRACT Ethnic residential segregation remains a central challenge for urban integration in an era of rising international and internal migration. While prior research has focused primarily on selective mobility mechanisms—such as white flight and native avoidance—the role of in‐movers' settlement patterns in shaping segregation trajectories is less well understood. This study examines how the arrival of in‐movers influences residential segregation in Stockholm by analysing their direct settlement choices, the indirect effects of their arrival on current residents' mobility decisions, and the cumulative long‐term consequences of these processes. Using rich Swedish population registers linked to an empirically calibrated simulation model, we show that immigrant and native in‐movers contribute to segregation through distinct pathways. Immigrant in‐movers disproportionately settle in neighbourhoods with higher shares of immigrants, and their arrival increases the likelihood that existing immigrant residents relocate to these same areas, reinforcing clustering over time. Native in‐movers, by contrast, exhibit a dual effect: although they preferentially settle in native‐majority neighbourhoods, their arrival also attracts some immigrant residents, partially counterbalancing segregation pressures. Taken together, these findings demonstrate that segregation dynamics are shaped not only by internal mobility but also by the arrival of in‐movers and the behavioural responses of current residents to them, underscoring the central role of migration‐driven mechanisms in contemporary urban segregation.
