A longstanding finding is that neighborhood racial segregation is linked to violence. In this paper, we look beyond neighborhoods of residence to consider the everyday mobility of urbanites in their daily rounds. Analyzing estimates of neighborhood mobility from largescale social media data in the 50 largest American cities, we find that residential segregation by race is not only associated with higher violence but also lower equitability of travel across neighborhoods and a lower concentration of visits to common hubs. Further, the interaction of equitable and concentrated mobility is significantly associated with rates of violence, controlling for both racial and income segregation, education, city size, and density. There is little evidence, however, that patterns of everyday mobility mediate the influence of residential racial segregation. Both dimensions of the structural connectedness of cities—one rooted in place of residence, and the other encompassing interneighborhood exposure based on travel throughout the metropolis—are implicated in violence.

超越居民隔离：大城市中基于流动性的联系和暴力发生率

一个长期的发现是，邻里种族隔离与暴力有关。在本文中，我们不仅仅考虑居住区，还考虑了城市居民在日常工作中的日常流动性。通过分析美国50个最大城市中大型社交媒体数据对邻里流动性的估计，我们发现，按种族进行的居住隔离不仅与暴力行为加剧有关，而且与跨社区旅行的公平性较低以及对公共枢纽的访问集中度较低有关。此外，公平和集中流动的相互作用与暴力发生率显着相关，控制着种族和收入隔离，教育，城市规模和人口密度。然而，几乎没有证据表明，日常出行方式可以调节居民种族隔离的影响。
