Columbiana County comprises the Salem, OH Micropolitan Statistical Area, which is also included in the larger Youngstown–Warren–Salem, OH Combined Statistical Area. Due to its location, Columbiana County is traditionally considered a part of Appalachian Ohio. While northern communities are more associated with Northeast Ohio, southern communities generally share more in common culturally with Greater Pittsburgh and the Upper Ohio Valley. The largely rural county sits midway between the two urban clusters. Officially considered part of the Youngstown media market, the Steubenville market media stations regularly report in the area as well.
