Changing Income Inequality in Nonmetropolitan Counties, 1980 to 1990*

Abstract Income inequality has been increasing across the United States, but little is known about changing income inequality in nonmetropolitan counties. Data from the 1980 and 1990 Summary Tape Files of the U.S. Census of Population and Housing are used to estimate ordinary least squares models of change in income inequality. Household income inequality increased in a smaller share of nonmetro than metro counties from 1980 to 1990, and increases in income inequality were influenced more strongly by economic restructuring in nonmetro than in metro counties. Other factors, such as change in household structure, demographic composition, and labor supply and job quality, were generally similar in affecting income inequality in nonmetro and metro counties. The greater importance of economic restructuring in nonmetro counties indicates the lesser diversity and smaller size of local economies, and their greater vulnerability to forces of economic restructuring.
