The oft-studied phenomenon of population dispersal from central city areas has often solely focused on examining the massive migration to suburban areas, but fewer scholars have examined decentralization trends within major central city areas. Written by Alan Berube and Benjamin Forman (under the auspices of the Brookings Institution), this 20-page report details the primary findings of their investigation into the growth of "outer-ring" city neighborhoods in close proximity to the nearest outlying suburban areas. Utilizing 2000 Census information for the 100 largest cities in the US, the authors demonstrate that, while many central cities grew in population since 1990, the growth continued to be uneven, and that relatively little population growth occurred in "inner-core" communities. Concluding that "decentralization is occurring even inside city borders," this analysis is a well-designed addition to the literature surrounding urban demographics and will be a good resource for metropolitan policy makers.
