About Jeffrey City
Jeffrey City is a former uranium mining boomtown located in Fremont County, in the central part of the U.S. state of Wyoming. The town is known in Wyoming and the American West as symbol of a boomtown that went "bust" very quickly, as the mine was shut down in 1982 and over 95% of the inhabitants left the town within three years. The population was 58 at the 2010 census, far lower than its onetime population of several thousand people. For statistical purposes, the United States Census Bureau has defined Jeffrey City as a census-designated place (CDP).
