The near doubling of Mason's population in the past decade has shaken that small-town atmosphere, as the corridor between Cincinnati and Dayton turned from farmland into a nearly seamless string of cityscapes. Census data show that Warren County, where Mason is situated between Dayton and Cincinnati, grew 39 percent in population between 1990 and 2000. Mason's population jumped from 11,452 in 1990 to 22,016 in 2000. Its land area has spread from 12 to 18 square miles.
