Segregation as a multiscalar phenomenon and its implications for neighborhood-scale research: the case of South Seattle 1990-2010

摘要

Neighborhoods and neighborhood change are often at least implicitly understood in relation to processes taking place at scales both smaller than and larger than the neighborhood itself. Until recently our capacity to represent these multiscalar processes with quantitative measures has been limited. Recent work on segregation profiles by Reardon and collaborators expands our capacity to explore the relationship between population measures and scale. With the methodological tools now available, we need a conceptual shift in how we view population measures in order to bring our theories and measures of neighborhoods into alignment. I argue that segregation can be beneficially viewed as multiscalar; not a value calculable at some correct scale, but a continuous function with respect to scale. This shift requires new ways of thinking about and analyzing segregation with respect to scale that engage with the complexity of the multiscalar measure. Using block-level data for eight neighborhoods in Seattle, Washington, I explore the implications of a multiscalar segregation measure for understanding neighborhoods and neighborhood change from 1990 to 2010.
