The Maysville Micropolitan Statistical Area (μSA), as defined by the United States Census Bureau, is coterminous with Mason County, Kentucky, whose county seat and largest city is Maysville. As of the 2010 census, the population of Mason County and the current μSA was 17,490, and 2014 Census Bureau estimates place the population at 17,166.[1]
Prior to a 2013 change in Census Bureau definitions, the Maysville μSA also included Lewis County, Kentucky. At that time, the μSA was redefined to consist solely of Mason County, and was also added as part of the Cincinnati-Wilmington-Maysville Combined Statistical Area.
As of the 2000 census, the μSA, which then consisted of Mason and Lewis Counties, had a population of 30,892 (though a July 1, 2009 estimate placed the population at 31,130).[2]
