The lasting impact of historical residential security maps on experienced segregation
研究1930年代住宅安全地图对当代经历性隔离的影响，利用地理位置数据比较相邻不同信用等级社区，发现低评级社区居民更常访问其他低评级及低收入、低教育水平社区，且非通勤或收入差异所致。
Abstract We study the impact of 1930s Residential Security maps on experienced segregation as measured by geolocation data. We compare adjacent neighborhoods with different creditworthiness grades. Using a sample of neighborhood boundaries, which, based on estimated propensity scores, were likely drawn for idiosyncratic reasons, residents of neighborhoods on the lower graded side of the boundary are more likely to visit other historically lower graded destination neighborhoods and neighborhoods that currently tend to have lower household income and lower educational attainment. Disparities in visits are not driven by work commutes, very local visits, or differences in income.
