Residential segregation has been intensively studied in the past decades. The growing availability of high-resolution residential mobility data has encouraged the analysis of mobility patterns, to disentangle the dynamics of residential sorting processes. However, to date, no systematic method has been proposed for the analysis of sorting trends. In this research, a methodological framework was designed specifically to examine such trends. The framework enables determining whether residential mobility patterns reflect a fixed, increasing or decreasing tendency to segregate over time, and to assess the extent of trend changes. It is based on a socio-spatial mobility approach, which regards residential moves between neighborhoods as moves between social positions, and on the application of concepts and measures from social mobility research. It can be applied in the context of various segregation criteria, such as income, ethnic origin and race.
Implementing the method, two empirical analyzes were conducted, focusing on the Tel-Aviv metropolitan area; the first dealing with residential sorting by income, and the second with the spatial assimilation of immigrants from the Former Soviet Union. A unique database constructed for the study includes a 50% sample of all individual moving records within the Tel-Aviv metropolitan area from 1997 to 2008 (approximately 700,000 records), and appended socioeconomic attributes of all origin and destination neighborhoods (908 metropolitan neighborhoods) for each year respectively.
With respect to income sorting, the results indicate that residential mobility patterns are associated with the segregation of affluence rather than the segregation of poverty; in addition, the main contribution of mobility to segregation is at the inter-locality rather than at the intra-locality level. With respect to immigrants’ spatial assimilation, the research shows an increasing tendency of immigrants to spatially integrate into the host society. The analysis also reveals a trade-off between immigrants' upward mobility in terms of neighborhood socioeconomic status and mobility to neighborhoods with higher shares of compatriots.
The method and its potential applications open new possibilities in the analysis of residential sorting trends. It is the first work explicitly applying concepts and methods from social mobility research to the fields of residential mobility and segregation. Thus, it contributes to the continuous interdisciplinary interaction between the fields of inequality economics and segregation.
