Despite widespread interest in spatializing sociology, consideration of space in research on stratification remains limited. Well-recognized, coherent literatures on stratification are found mainly at two opposite spatial scales, the city and the cross-national level. A large urban literature explores inequalities of poverty, racial segregation, crime, and other conditions within and across cities. Much of it focuses on large, world cities such as New York, Chicago, Los Angeles, and Atlanta. At the other extreme, cross-national literature charts the socioeconomic position of entire nations in the global system. But there is a missing middle: large swathes of places, people, and substantive topics are not systematically investigated because they fail to fall into the relatively binary pattern by which sociologists carve up space. Illustrating this lack of attention is that sociology has no customary term for the middle geographic scale between city and nation-state. © 2007 State University of New York. All rights reserved.
