基于人口普查区域的居住隔离文献依赖于地理规模和邻近性的问题假设。我们追求一种新的无痕迹的方法,结合明确的空间概念和方法来研究不同大小的自我中心的地方环境中的种族隔离。使用2000年美国100个最大的大都市区的人口普查数据,我们计算了一个空间修改版本的信息理论指数H来描述不同尺度下的黑人-白人,西班牙裔-白人,亚裔-白人和多群体隔离模式。大都市的结构特征,最好区分微观隔离从宏观隔离为每个组的组合,其影响被分解成部分,由于种族的变化发生在短距离和长距离。比较我们的结果,从轨道为基础的分析证实了新方法的价值。
The census tract-based residential segregation literature rests on problematic assumptions about geographic scale and proximity. We pursue a new tract-free approach that combines explicitly spatial concepts and methods to examine racial segregation across egocentric local environments of varying size. Using 2000 census data for the 100 largest U.S. metropolitan areas, we compute a spatially modified version of the information theory index H to describe patterns of black-white, Hispanic-white, Asian-white, and multi-group segregation at different scales. The metropolitan structural characteristics that best distinguish micro-segregation from macro-segregation for each group combination are identified, and their effects are decomposed into portions due to racial variation occurring over short and long distances. A comparison of our results to those from tract-based analyses confirms the value of the new approach.
