The document summarizes the impacts of industrial decentralization in metropolises like Istanbul, Turkey. 1) Industrial decentralization has led to the emergence of five new social classes in Istanbul's labor force, including skilled workers employed locally and various informal/temporary workers. 2) It has also contributed to the redistribution of urban revenues and caused conflicts between globalized elites and local groups. 3) One result is the rise of a new social group of self-employed workers providing services flexibly within the city.
