Industry specialization varies across rural counties

Map showing U.S. nonmetro county economic types

The ERS county economic typology codes are a classification system that provide a tool to analyze and characterize the economic dependence of U.S. counties. This typology reveals that rural (nonmetropolitan) counties have diverse industrial specializations. Where farming was once almost synonymous with rural, the predominance of farming as an industry in rural areas of the United States is now largely confined to the Plains States, and only 6 percent of the rural population in 2015 lived in the 391 rural farming-dependent counties. In contrast, although also declining in number, manufacturing predominated in the economies of a similar number of rural counties (351)—concentrated mainly east of the Mississippi but also including a scattering of counties further west—and these account for about 22 percent of the rural population. The 183 rural mining dependent counties accounted for 7 percent of rural population in 2015, and were the only economic type among rural counties to see strong population growth (1.6 percent) in 2010-15. A version of this map is found in the Amber Waves article, “ERS County Economic Types Show a Changing Rural Landscape,” and the underlying codes may be found in the ERS data product, County Typology Codes.
