US Minority Migration and Metropolitan Change

描述（由申请人提供）：本研究建议评估与种族-民族再分配相关的移民过程-在1975-2000年期间跨越和美国大都市地区-以检测更大的少数民族分散的趋势。在过去的三十年里，美国的种族和少数民族人口的规模和多样性急剧增加，但他们也表明，这些人口在大都市地区以及在大都市地区内部的分布相当不均匀。 西班牙裔和亚裔人口集中在纽约、洛杉矶和其他几个大都市地区，这与他们最近的移民身份和对这些地区同种族社区的依恋有关。然而，最近的200 '0年人口普查结果表明，他们的地理分布更加分散。非洲裔美国人虽然不如这些群体集中，但越来越倾向于迁往南方，扭转了长期以来的反向流动。 在大都市地区，所有这三个群体都比非西班牙裔白人更集中在中心城市和选定的内郊区社区。然而，这三个城市都表现出更大的郊区化趋势，这在吸引更多少数民族的不断发展的大都市地区更为明显。 这些大都市间的迁移过程，和大都市内的少数民族再分配模式将在本研究中进行评估，从1980年，1990年和2000年美国人口普查的“居住五年前”的问题分析。这项研究将评估这些移徙过程在多大程度上导致少数种族和族裔在大都市地区之间和内部更加分散。 该项目涉及一个由人口学家、社会学家和地理学家组成的团队，以及具有GIS（地理信息系统）专业知识的顾问，以协助对大都市地区进行分类，进行移民建模，并使用标准人口统计方法评估移民过程的影响。

DESCRIPTION (provided by applicant): This research proposes to evaluate migration processes associated with race-ethnic redistribution -- both across and within large US metropolitan areas over the period 1975-2000 -- to detect tendencies toward greater minority dispersal. The last three decades have shown a dramatic rise in the size and diversity of the nation's race and ethnic minority populations, but they have also shown these populations to be quite unevenly distributed across metropolitan areas as well as within them. The concentration of Hispanic and Asian populations in New York, Los Angeles, and a few other large metropolitan areas is related to their recent immigrant status and attachments to co-ethnic communities in those areas. Yet, recent Census 200'0 results suggest their greater geographic dispersal. The African-American population, while less concentrated than these groups, has shown an increased tendency to relocate in the South reversing a long-standing movement in the reverse direction. Within metropolitan areas, all three groups are more concentrated in central cities and selected inner suburb communities, than non-Hispanic whites. Yet, all three have shown tendencies toward greater suburbanization, which have been more apparent in growing metropolitan areas which are attracting more minorities. The migration processes underlying these inter-metropolitan, and intra-metropolitan minority redistribution patterns will be evaluated in this study from analyses of the "residence five-years ago" question from the 1980, 1990, and 2000 US censuses of population. The study will assess the extent to which these migration processes are leading to a greater dispersion of race and ethnic minorities both across and within large metropolitan areas. This project involves a team of demographers, sociologists, and geographers as well as consultants with GIS (Geographical Information Systems) expertise to assist in classifying metropolitan areas, conducting migration modeling, and evaluating the impacts of migration processes using standard demographic methods.
