The city was named for John Young. He was an early settler from Whitestown, New York, who started the town's first sawmill and gristmill. Youngstown is in an area of the United States that is often called the Rust Belt. The town was known as a center of steel making. Youngstown was forced to change itself when the U.S. steel industry fell into decline in the 1970s. Towns in the area did not have a lot of business after that. Youngstown also falls within the Appalachian Ohio region, among the foothills of the Appalachian Mountains. The 2010 census showed that Youngstown had a total population of 66,982, making it Ohio's ninth largest city. The city has had a decline of over 60% of its population since 1960.
