means The long-term decline of manufacturing and heavy industry in a region or economy, as factories close, jobs disappear, and the local economy shifts toward services.

from A 20th-century coinage built from 'industrialization' plus the undoing prefix 'de-'. 'Industry' itself traces back to the Latin 'industria', meaning diligence or active effort. The word 'deindustrialization' gained real traction in the later 1900s as economists and journalists needed a term for whole regions — steel towns, mill towns, mining valleys — watching their industrial base hollow out and move elsewhere.
