Mansfield is a city in the U.S. state of Ohio and the county seat of Richland County. The municipality is located in north-east/north-central Ohio in the western foothills of the Allegheny Plateau, approximately 66 miles (106 km) southwest of Cleveland and 66 miles (106 km) northeast of Columbus.
It was founded in 1808 on a fork of the Mohican River in a hilly region surrounded by fertile farmlands, and became a manufacturing center owing to its location with numerous railroad lines. After the decline of heavy manufacturing, the city's industry has since diversified into a service economy, including retailing, education, and healthcare sectors. The 2010 Census showed that the city had a total population of 47,821, making it Ohio's nineteenth largest city.
According to the 2010 Census, the Mansfield, OH Metropolitan Statistical Area (MSA) has a population of 124,475 residents, while the Mansfield-Bucyrus, OH Combined Statistical Area (CSA) has 168,259 residents.
