The transition to nonmetropolitan population deconcentration.

A major aim of this study is to address our lack of understanding of rural-urban population change within nonmetropolitan counties of the United States. Specifically, we (a) examine trends between 1950 and 1975 in differential rural and urban growth rates within nonmetropolitan countries, and (b) examine the relationship between county location/function and within-county deconcentration. We show that the post-1970 period has not simply marked the net shift of population from metropolitan to nonmetropolitan areas, but has also ushered in a pattern of population deconcentration within most nonmetropolitan areas. It is also clear that traditional ecological base variables have been of diminishing utility in explaining deconcentration during the 1970s, suggesting that deconcentration is now evident in nonmetropolitan counties characterized by a broad spectrum of economic and sociodemographic traits.
