Rural-Urban Continuum 2013, Grouped
The U.S. Department of Agriculture Economic Research Service’s 2013 Rural-Urban Continuum Codesexternal icon form a classification scheme that distinguishes metropolitan counties by the population size of their metro area, and nonmetropolitan counties by degree of urbanization and adjacency to a metro area.
This variable in this database groups the 2013 Rural-Urban Continuum Codes (also referred to as the Beale Codes) into 3 categories: metropolitan counties (rural-urban continuum codes 1–3), nonmetropolitan counties (rural-urban continuum codes 4–9), and unavailable (blank or unknown).
Categorizing counties by population size helps researchers investigate geographic correlates of the burden of cancer in the area of interest.
