After Hague's retirement from politics, a series of mayors including John V. Kenny, Thomas J. Whelan and Thomas F. X. Smith attempted to take control of Hague's organization, usually under the mantle of political reform. None were able to duplicate the level of power held by Hague, but the city and the county remained notorious for political corruption for years. By the 1970s the city experienced a period of urban decline that saw many of its wealthy residents leave for the suburbs, due to rising crime, civil unrest, political corruption, and economic hardship. From 1950 to 1980, Jersey City lost 75,000 residents, and from 1975 to 1982, it lost 5,000 jobs, or 9% of its workforce.
