The Great Depression took its toll on the Argyle area, and the population declined to only ninety in 1950. Argyle incorporated as a separate city on September 19, 1960, with M.H. Wilson as the first mayor. Gradually the town grew in population as more people from the Dallas-Fort Worth area discovered its rural charm. By the 1970s a number of retail establishments were located in Argyle, and the population reached 1,575 in 1990, and doubled from that figure to 3,282 at the 2010 census. The high rate of growth is expected to continue as part of the general development of northern areas in the Dallas-Fort Worth metroplex.
