整合的障碍:物理边界与居住隔离的空间结构

Barriers to Integration: Physical Boundaries and the Spatial Structure of Residential Segregation

Elizabeth Roberto, Jackelyn Hwang

摘要:

尽管自民权时代以来,居住隔离水平略有下降,但隔离仍然是美国景观的一个决定性特征。这项研究强调了在衡量隔离时考虑物理障碍的重要性-城市环境的特点,这些特点使各个地点脱节。我们使用2010年十年一次的人口普查中的20个美国锈带城市的人口和地理数据,以及一种测量和分析隔离的新方法,该方法包括道路的连通性和物理障碍(如高速公路,铁路轨道和死胡同)造成的额外距离。我们发现,物理障碍划分城市空间的方式,加强或加剧隔离,但有很大的差异,在何种程度上,他们增加隔离,这些城市内部和跨和不同的民族群体。通过揭示城市居民所经历的隔离的一个新的变异来源,研究结果对理解导致隔离持续存在的机制和隔离的后果具有影响。

英文摘要:

Despite modest declines in residential segregation levels since the Civil Rights Era, segregation remains a defining feature of the U.S. landscape. This study highlights the importance of considering physical barriers--features of the urban environment that disconnect locations--when measuring segregation. We use population and geographic data for 20 U.S. Rustbelt cities from the 2010 decennial census and a novel approach for measuring and analyzing segregation that incorporates the connectivity of roads and the excess distance imposed by physical barriers, such as highways, railroad tracks, and dead-end streets. We find that physical barriers divide urban space in ways that reinforce or exacerbate segregation, but there is substantial variation in the extent to which they increase segregation both within and across these cities and for different ethnoracial groups. By uncovering a new source of variation in the segregation experienced by city residents, the findings have implications for understanding the mechanisms that contribute to the persistence of segregation and the consequences of segregation.
