The Youngstown–Warren, OH Metropolitan Statistical Area, typically known as the Mahoning Valley, is a metropolitan area in Northeast Ohio with Youngstown, Ohio, at its center. According to the U.S. Census Bureau, the metropolitan statistical area (MSA) includes Mahoning and Trumbull counties.[3] As of the 2020 census, the region had a population of 430,591, making it the 125th-largest metro area in the country.[2]

Taking its name from the Mahoning River, the area has a large commuter population that works in Cleveland and Pittsburgh and their metropolitan areas. It is located in the Rust Belt, the former industrial region of the northern United States. The Youngstown–Warren–Salem combined statistical area adds the Salem micropolitan area and Columbiana County, Ohio to the region, increasing the total population to 532,468.[4] The Youngstown–Warren media market serves all three counties in the CSA, as well as the Mercer County, Pennsylvania and Lawrence County, Pennsylvania.

Steel industry

Although steel has been produced in the Mahoning Valley since the mid-1800s, after the Civil War, the valley was primarily known for its iron production. Conversion to steel manufacturing began during the economic depression of the 1890s.[5] The Mahoning Valley is suitable for steel manufacture because of "its proximity to the Lake Erie ports that receive iron ore…the coal fields of Ohio, Pennsylvania and West Virginia; and to limestone deposits."[6] The "25-mile stretch of steel mills and related industries" along the Mahoning River is similar to the Ruhr Valley in Germany."[6] Historically, it was part of the largest steel producing region in the world, leading to the historical "Steel Valley" moniker that the area shared with the Pittsburgh metropolitan area.[citation needed]

The local steel industry declined during the 1970s steel crisis. A notable plant closure occurred on September 19, 1977, when Youngstown Sheet and Tube abruptly closed its Campbell Works and furloughed 5,000 workers.[7] Today the area produces little steel, and is home to many scrap metal yards and aluminum plants.[8] A 2009 documentary, Steel Valley: Meltdown, addresses "the past, present and future of the Mahoning Valley" through the eyes of local experts, including one local organizer who stated, "We are the first generation completely removed from the days when steel mills were active."[9]

The Mahoning Valley Economic Development Corporation, founded in 1979, is active in economic revitalization and diversification. It owns two industrial parks, and has purchased local rail lines, including the Youngstown and Austintown Railroad and the Warren and Trumbull Railroad.[10]
