US Minority Migration and Metropolitan Change

描述(由申请人提供)：这项研究建议评估1975-2000年间在美国大城市地区范围内和在大城市地区内与种族-民族重新分布相关的移民过程，以发现少数民族更大程度分散的趋势。在过去的三十年里，美国种族和少数民族人口的规模和多样性出现了戏剧性的增长，但它们也表明，这些人口在大都市地区以及大都市地区内部的分布相当不均匀。 拉美裔和亚裔人口集中在纽约、洛杉矶和其他几个大城市地区，与他们最近的移民身份和对这些地区同族社区的依恋有关。然而，最近的人口普查200：0结果表明，它们在地理上的分散度更大。非洲裔美国人人口虽然不像这些群体那样集中，但表现出在南方重新安置的趋势增加，扭转了长期向相反方向流动的趋势。 在大都市地区，与非西班牙裔白人相比，这三个群体都更集中在中心城市和选定的近郊社区。然而，这三个城市都表现出了更大的郊区化趋势，这在吸引更多少数民族的增长中的大都市地区更加明显。 这项研究将通过对1980年、1990年和2000年美国人口普查中“五年前居住”问题的分析，评估这些大都市间和大都市内少数民族再分布模式背后的移民过程。这项研究将评估这些移徙过程在多大程度上导致大都市地区和大都市地区内的种族和少数民族更加分散。 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，以及具有地理信息系统(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，并使用标准的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.
