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 Moreover, the evidence on mixed or integrated neighborhoods that does exist is out of date and methodologically limited.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.

这项研究的目的是记录和解释在 从1970年到1980年，都是种族混杂的城市社区。尽管他们 理论和政策上的重要性，种族混杂的地区只吸引了 社会科学家的附带兴趣。这种忽视可以追溯到 基于继承权和“小费”等概念的信念-- 种族融合是一种罕见的暂时现象。 此外，关于混合或一体化社区的证据确实存在 是过时的，在方法上也是有限的。 为了更好地了解种族混杂的社区是如何以及为什么发生变化的， 计划进行多阶段、多层次的分析。在第一阶段，人口普查 所有展览场地将收集按种族划分的人口数据。 1970年混合种族组成，分布在美国60个中心城市 在1970年或1980年有25万或更多的居民。这群人 将使用区域(N=2500)来解决以下描述性问题 1970年混合社区的发生率和种族变化的类型 他们在接下来的十年里所经历的。 分析的第二阶段检查先行因素和伴随因素 第一阶段描述的模式。在进行了系统的样本之后 从混合地区的人口中提取了1000例病例，甚至更多 收集了详细的数据，采用多元技术进行检验 关于1970年区域水平特征的另一种假设 预测这些地区种族构成变化的方向和程度 从1970年到1980年的街区。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 这伴随着社区种族构成的变化。 在研究的最后阶段，更大的城市背景的作用 将从三个方面进行探索。首先，执行区域级别的分析 在之前的阶段中，将对混合社区的子组重复 按选定的城市结构特征分类。第二，相同的 构造特征将与区域一起作为预测因素。 变量，对邻里关系变化进行跨层分析。最后， 将执行聚合级回归以确定哪些维度 城市结构的变化解释了城市(N=60)之间的差异 呈现不同种族类型的混合社区的比例 1970-80年期间的变化和变化的幅度。
