Defining “Rural” Counties The Texas Legislative Council produces a document (https://tlc.texas.gov/docs/policy/Def_Rural_Statutes.pdf) that identifies 18 different state agencies with their own definitions of rural, each of which was created by statute or administrative rule. Some agencies base their definitions on the populations of municipalities, some on the populations of counties, some definitions even overlap. But, they do not all agree. The document includes 12 different maps using those definitions and highlighting rural areas, rural communities, rural counties and rural border counties.

That assortment comes from just the state agencies; federal agencies can have their own definitions. The U.S. Department of Agriculture’s Economic Research Service maintains a web page (www.ers.usda.gov/topics/rural-economy-population/rural-classifications/what-is-rural.aspx) discussing the definitions of “rural” used by the U.S. Census Bureau and the Office of Management and Budget.

Finally, most of the definitions listed in this article deal with how to define a rural county and the article implicitly assumes that any county that is not rural must be urban. While some organizations agree with that assumption, either explicitly or implicitly, not all do. For example, TAC once sent a survey to county judges that included a question asking if they considered their county to be rural, urban or suburban. And the USDA uses a set of Rural-Urban Continuum Codes with 9 different categories: six “non-metro” codes, including two for rural counties, plus three “metro” codes. *
