Cleveland ( KLEEV-lənd), officially the City of Cleveland, is a major city in the U.S. state of Ohio, and the county seat of Cuyahoga County. It is located along the southern shore of Lake Erie, across the U.S. maritime border with Canada and approximately 60 miles (100 kilometers) west of the Ohio-Pennsylvania state border.
The largest city on Lake Erie, Cleveland anchors the Greater Cleveland Metropolitan Statistical Area (MSA) and the Cleveland–Akron–Canton Combined Statistical Area (CSA). The CSA is the most populous combined statistical area in Ohio and the 18th largest in the United States, with an estimated population of 3,586,918 in 2019. The city proper, with an estimated 2019 population of 381,009, ranks as the 53rd-largest city in the U.S., as a larger portion of the metropolitan population lives outside the central city. The seven-county metropolitan Cleveland economy, which includes Akron, is the largest in the state.
Cleveland was founded in 1796 near the mouth of the Cuyahoga River by General Moses Cleaveland, after whom the city was named. It grew into a major manufacturing center due to its location on both the river and the lake shore, as well as numerous canals and railroad lines. A port city, Cleveland is connected to the Atlantic Ocean via the Saint Lawrence Seaway. The city's economy relies on diversified sectors such as manufacturing, financial services, healthcare, biomedicals, and higher education.
