Passage:

A sociologist revisits a long-running dispute about whether urban neighborhoods change because of broad economic forces or because of the choices of individual residents. The sociologist grants that citywide shifts in employment and housing finance set the outer limits of what is possible. Yet the sociologist argues that many accounts treat those limits as if they directly determine outcomes, ignoring how residents and local organizations interpret constraints and then coordinate around those interpretations. In one neighborhood, a modest increase in rents triggered rapid turnover not because the increase made the area objectively unaffordable for all long-time tenants, but because a few widely discussed departures convinced remaining residents that the area had entered an irreversible transition. Local landlords then raised rents more aggressively, and small businesses altered their offerings, actions that made the feared transition self-fulfilling. The sociologist concludes that structural conditions matter most when they are translated into shared expectations that reorganize local behavior.
