Among the survey years used for state-level estimation only (2006–2007, 2007–2008, 2008–2009), the survey design did not include provision of stratum-specific estimates; therefore, county type data was not estimated for these years.

d

Terms used to classify each Ohio county into one of four categories: Appalachian: designated by the Appalachian Regional Commission; metropolitan: a non-Appalachian county that contains at least one city with 50,000 or more inhabitants; suburban: a non-metropolitan, non-Appalachian county that meets the US Census definition of an urbanized area); and rural/non-Appalachia: all other counties not classified as Appalachian, metropolitan, or suburban.
