项目摘要

The purpose of the research is to document and explain changes occurring in racially-mixed urban neighborhoods from 1970 to 1980. Despite their theoretical and policy importance, racially-mixed areas have attracted only incidental interest from social scientists. This neglect can be traced to the belief--founded on concepts such as succession and "tipping"--that racial integration constitutes an infrequent, temporary phenomenon. Moreover, the evidence on mixed or integrated neighborhoods that does exist is out of date and methodologically limited. To better understand how and why racially-mixed neighborhoods change, a multi-stage, multi-level analysis is planned. In the first stage, census data on population by race will be collected for all tracts exhibiting mixed racial compositions in 1970 and located in the 60 U.S. central cities with 250,000 or more inhabitants in either 1970 or 1980. This population of tracts (N = 2500) will be used to address descriptive issues concerning the incidence of mixed neighborhoods in 1970 and the types of racial change experienced by them over the ensuing decade. The second stage of the analysis examines antecedents and concomitants of the patterns described in the first stage. After a systematic sample of 1000 cases has been drawn from the population of mixed tracts and more detailed data assembled, multi-variate techniques will be employed to test alternative hypotheses about the 1970 tract-level characteristics that predict the direction and magnitude of racial compositional change in these neighborhoods from 1970 to 1980. The other major task during this stage involves an assessment of the non-racial demographic and housing trends that accompany changes in neighborhood racial composition. In the last stage of the research, the role of the larger urban context will be explored in three ways. First, the tract-level analyses performed in prior stages will be repeated for subgroups of mixed neighborhoods categorized by selected urban structural characteristics. Second, the same structural characteristics will serve as predictors, along with tract variables, in a cross-level analysis of neighborhood change. Finally, aggregate-level regressions will be preformed to determine which dimensions of urban structure explain variation across cities (N = 60) in the proportions of mixed neighborhoods exhibiting different types of racial change and in the magnitude of such changes for the period 1970-80.

研究的目的是记录和解释发生的变化 1970 年至 1980 年间种族混居的城市社区。理论上和政策的重要性，种族混合地区只吸引了社会科学家的偶然兴趣。这种忽视可以追溯到这种信念——建立在继承和“小费”等概念的基础上—— 种族融合是一种罕见的、暂时的现象。此外，确实存在混合或综合社区的证据已经过时并且方法有限。为了更好地了解种族混合社区如何以及为何发生变化，计划进行多阶段、多层次的分析。第一阶段，人口普查将为所有展示区域收集按种族划分的人口数据 1970年混合种族构成，分布于美国60个中心城市 1970 年或 1980 年有 250,000 或更多居民。这个人口的小册子（N = 2500）将用于解决有关的描述性问题 1970 年混合社区的发生率以及种族变化的类型他们在接下来的十年里所经历的。分析的第二阶段检查前因和伴随因素第一阶段中描述的模式。经过系统抽样已从混合地区及更多地区的人口中抽取了 1000 例病例收集详细数据，将采用多变量技术进行测试关于 1970 年地区特征的替代假设预测这些地区种族构成变化的方向和幅度 1970年至1980年的社区。这一阶段的另一项主要任务涉及对非种族人口和住房趋势的评估伴随着社区种族构成的变化。在研究的最后阶段，更大的城市环境的作用将从三个方面进行探讨。首先，进行区域级分析对于混合社区的子群体，将重复先前阶段的操作按选定的城市结构特征进行分类。二、同样结构特征将作为预测因子，以及区域变量，在邻里变化的跨层次分析中。最后，将执行聚合级别回归以确定哪些维度城市结构的差异解释了不同城市 (N = 60) 的差异表现出不同种族类型的混合社区的比例 1970-80 年间的变化以及这种变化的幅度。
