Mahoning County is a northeastern Ohio county, centered on the city of Youngstown — once one of the great steel cities of America and now a symbol both of the industrial decline that swept the Rust Belt and the grassroots resilience being mustered in its wake. The county straddles the Ohio-Pennsylvania border along the Mahoning River valley and was home to spectacular blast furnaces and rolling mills that made Youngstown steel integral to American industrial might for over a century. The Black Monday of September 19, 1977 — when the Youngstown Sheet and Tube Company closed its Campbell Works, eliminating 5,000 jobs overnight — is considered by many economists and historians to mark the beginning of the American deindustrialization era. Today, Youngstown State University anchors economic recovery alongside healthcare employers including Mercy Health – St. Elizabeth and Ultium Cells. The Youngstown Business Incubator has become a nationally recognized model for innovation-driven urban revitalization. The Youngstown Phantoms (USHL hockey) provide local sports entertainment.
