ABSTRACT

This paper describes how the Modified Lilien Index (MLI) can be used to measure the rate of neighborhood racial and ethnic change. The MLI is useful because it measures the rate of change across multiple racial and ethnic groups. It also weights the rate of change for each neighborhood based on changes in the racial and ethnic composition of the entire population, which helps contrast neighborhoods undergoing high and low rates of change compared to the nation as a whole. Using harmonized census data, we demonstrate the utility of the MLI by analyzing neighborhood change across four groups—White, Black, Latino, and Asian—from 1970 to 2010. We find that the rate of racial and ethnic change decreased substantially during this time period, but also that there is significant variation in this trend at the regional and metropolitan level. Based on these results, we suggest that the MLI can be used to identify emergent geographies of neighborhood racial and ethnic change within a broader territory and to quantify how change impacts community structure and the outcomes of individuals.

摘要

本文介绍了如何使用修正的 Lilien 指数 (MLI) 来衡量社区种族和民族变化的速度。MLI 很有用，因为它衡量了多个种族和族裔群体的变化率。它还根据整个人口的种族和民族构成的变化对每个社区的变化率进行加权，这有助于对比与整个国家相比变化率高和低的社区。使用统一的人口普查数据，我们通过分析 1970 年至 2010 年四个群体（白人、黑人、拉丁裔和亚裔）的邻里变化来证明 MLI 的效用。我们发现，在此期间种族和民族变化率大幅下降，但在区域和大都市层面，这一趋势也存在显着差异。
