Racial and ethnic segregation in U.S. metropolitan areas contributes to the existence of neighborhood poverty, with segregation typically conceptualized as occurring between central city and suburban neighborhoods due to the racially exclusive nature of suburbanization through much of the twentieth century. However, increasing suburbanization across race, ethnicity and socioeconomic status since around 1970 has complicated the spatial structure of residential inequalities among metropolitan areas. In this study, I assess how patterns of racial and ethnic inequality in exposure to neighborhood poverty changed across urban and suburban locations since 1980, and I investigate how different dimensions of segregation by race and ethnicity correspond to worsened racial and ethnic inequality in exposure to disadvantaged neighborhoods in urban as well as suburban areas. To study differences between suburbs, I contribute a novel approach for measuring suburban neighborhoods based on their density, housing stock age and overall degree of development. Results demonstrate how the conventional city-suburb dichotomy masks substantial differences between suburbs in (a) Black, Latino and White exposure to neighborhood disadvantage and (b) the degree to which patterns of segregation by race and ethnicity exacerbate Black–White and Latino–White inequalities in exposure to suburban neighborhood disadvantage. Black–White segregation exacerbates Black exposure to neighborhood poverty across space, especially in cities and older suburbs, while Latino–White segregation worsens Latino exposure to poor neighborhoods in cities as well as farther-flung rural and exurban areas.

美国大都市地区的种族和种族隔离导致了邻里贫困的存在，由于在整个20世纪的大部分时间里郊区化的种族排他性，种族隔离通常被概念化为发生在中心城市和郊区之间。但是，自1970年左右以来，随着种族，族裔和社会经济地位的不断郊区化，使大城市地区居民不平等的空间结构变得复杂。在这项研究中，我评估了自1980年以来，城市和郊区在邻里贫困中所遭受的种族和族裔不平等的模式是如何变化的，我研究了按种族和种族划分的不同维度如何对应于城市和郊区处于不利地位的社区所面临的加剧的种族和族裔不平等。为了研究郊区之间的差异，我提供了一种新颖的方法来根据郊区的密度，房屋存续年龄和总体发展程度来测量郊区。结果表明，传统的城市郊区二分法如何掩盖郊区之间在（a）黑人，拉丁裔和白人遭受邻里不利的巨大差异，以及（b）种族和种族隔离模式加剧黑人-白人和拉丁裔-白人的程度不平等在郊区居民中的不利地位。黑白隔离加剧了黑人在整个太空中遭受邻里贫困的风险，
