Cities such as Detroit, Buffalo and Youngstown, Ohio have experienced severe economic decline in the 21st century due to what phenomenon?
Explanation
Answer: C -Cities such as Detroit, Buffalo, and Youngstown, Ohio have experienced severe economic decline in the 21st century due to deindustrialization-a phenomenon in which workers lose their jobs due to increased industrial (mechanical) productivity or because the jobs are moved to an area with cheaper labor. While outsourcing can lead to deindustrialization, it is not the sole cause of the phenomenon. Detroit (and nearby Flint, Michigan), Buffalo and Youngstown were all cities with local economies driven by manufacturing. As manufacturing jobs were terminated or relocated, the local economies began to crash.
