Rust Belt

The Rust Belt, formerly the Steel Belt or Factory Belt, is an area of the United States that underwent substantial industrial decline in the late 20th century. The region is centered in the Great Lakes and Mid Atlantic regions of the United States. Common definitions of the Rust Belt include Ohio, Indiana, Northern Illinois, southeastern Wisconsin, Michigan, Pennsylvania, and Upstate New York. Some broader geographic definitions of the region include parts of Central Illinois, Iowa, Kentucky, Maryland, Minnesota, Missouri, New Jersey, and West Virginia. The term "Rust Belt" is considered to be a pejorative by some people in the region.

Between the late 19th century and late 20th century, the Rust Belt formed the industrial heartland of the country, and its economies were largely based on iron and steel, automobile manufacturing, coal mining, and the processing of raw materials. The term "Rust Belt", derived from the substance rust, refers to the socially corrosive effects of economic decline, population loss, and urban decay attributable to deindustrialization. The term gained popularity in the U.S. beginning in the 1980s, when it was commonly contrasted with the Sun Belt, whose economy was then thriving.

The Rust Belt experienced industrial decline beginning in the 1950s and 1960s, with manufacturing peaking as a percentage of U.S. GDP in 1953 and declining incrementally in subsequent years and especially in the late 1970s and early 1980s. Demand for coal declined as industry turned to oil and natural gas, and U.S. steel was undercut by competition from Germany and Japan. High labor costs in the Rust Belt were also a factor in encouraging the region's heavy manufacturing companies to relocate to the Sun Belt or overseas or to discontinue entirely. The U.S. automotive industry also declined as consumers turned to fuel-efficient foreign-manufactured vehicles after the 1973 oil crisis raised the cost of gasoline and foreign auto manufacturers began opening factories in the U.S., which were largely not strongly unionized like the U.S. auto manufacturers in the Rust Belt. Families moved away from Rust Belt communities, leaving cities with falling tax revenues, declining infrastructure, and abandoned buildings. Major Rust Belt cities include Baltimore, Buffalo, Chicago, Cincinnati, Cleveland, Detroit, Milwaukee, Philadelphia, Pittsburgh, Rochester, and St. Louis. New England was also hit hard by industrial decline, but cities closer to the East Coast, including in the metropolitan areas of Boston, New York, and Washington, D.C. were able to adapt by diversifying or transforming their economies, shifting to services, advanced manufacturing, and high-tech industries.

Since the 1980s, presidential candidates have devoted much of their time to the economic concerns of the Rust Belt region, which includes several populous swing states, including Michigan, Ohio, Pennsylvania, and Wisconsin. These states were crucial to Republican Donald Trump's victories in the 2016 and 2024 presidential elections.

In the 20th century, local economies in these states specialized in large-scale manufacturing of finished medium to heavy industrial and consumer products, and the transportation and processing of the raw materials required for heavy industry. The area was referred to as the Manufacturing Belt, Factory Belt, or Steel Belt as distinct from the agricultural Midwestern states forming the so-called Corn Belt and Great Plains states that are often called the "breadbasket of America".

The flourishing industrial manufacturing in the region was caused in part by the proximity to the Great Lakes waterways, and abundance of paved roads, water canals, and railroads. After the transportation infrastructure linked the iron ore found in the so-called Iron Range of northern Minnesota, Wisconsin and Upper Michigan with the coking coal mined from the Appalachian Basin in Western Pennsylvania and Western Virginia, the Steel Belt was born. Soon it developed into the Factory Belt with its manufacturing cities: Chicago, Buffalo, Detroit, Milwaukee, Cincinnati, Toledo, Cleveland, St. Louis, Youngstown, and Pittsburgh, among others. This region for decades served as a magnet for immigrants from Austria-Hungary, Poland, and Russia, as well as Yugoslavia, Italy, and the Levant in some areas, who provided the industrial facilities with inexpensive labor. These migrants drawn by labor were also accompanied by African Americans during the Great Migration who were drawn by jobs and better economic opportunity.

Following several "boom" periods from the late-19th to the mid-20th century, cities in this area struggled to adapt to a variety of adverse economic and social conditions. From 1979 to 1982, known as the Volcker shock, the U.S. Federal Reserve decided to raise the base interest rate in the United States to 19%. High-interest rates attracted wealthy foreign "hot money" into U.S. banks and caused the U.S. dollar to appreciate. This made U.S. products more expensive for foreigners to buy and also made imports much cheaper for Americans to purchase. The misaligned exchange rate was not rectified until 1986, by which time Japanese imports, in particular, had made rapid inroads into U.S. markets.

From 1987 to 1999, the U.S. stock market went into a stratospheric rise, and this continued to pull wealthy foreign money into U.S. banks, which biased the exchange rate against manufactured goods. Related issues include the decline of the iron and steel industry, the movement of manufacturing to the southeastern states with their lower labor costs, the layoffs due to the rise of automation in industrial processes, the decreased need for labor in making steel products, new organizational methods such as just-in-time manufacturing which allowed factories to maintain production with fewer workers, the internationalization of American business, and the liberalization of foreign trade policies due to globalization. Cities struggling with these conditions shared several difficulties, including population loss, lack of education, declining tax revenues, high unemployment and crime, drugs, swelling welfare rolls, deficit spending, and poor municipal credit ratings.
