In this article, we assess trends in residential segregation in the United States from 1960 to 2000 along several dimensions of race and ethnicity, class, and life cycle and present a method for attributing segregation to nested geographic levels. We measured segregation for metropolitan America using the Theil index, which is additively decomposed into contributions of regional, metropolitan, ...

As all these megacities have influenced the population and employment structure in a region extending well beyond their official boundaries, three zones are defined for each megacity: the metropolitan...

Invertebrate assemblages in metropolitan areas where forests or shrublands were being converted to urban land were strongly related to urban intensity. In metropolitan areas where agriculture and grazing lands were being converted to urban land, inver...

The authors find evidence of income convergence across all substate labor markets in the lower forty-eight U.S. states during the 1969 to 1999 period. However, convergence is not expressed in a uniform way across metropolitan/nonmetropolitan regions, across time periods, or across census regions. The authors show that catching up within the distribution is more common for nonmetropolitan region...
