According to the [[2010 United States Census|2010 census]], it had a population of 14,666.<ref name="QF">{{cite web|title=State & County QuickFacts|url=http://quickfacts.census.gov/qfd/states/17/17125.html|publisher=United States Census Bureau|accessdate=July 7, 2014}}</ref> Its [[county seat]] is [[Havana, Illinois|Havana]].<ref name="GR6">{{cite web|url=http://www.naco.org/Counties/Pages/FindACounty.aspx|accessdate=2011-06-07|title=Find a County|publisher=National Association of Counties}}</ref> The county is named in honor of [[George Mason]], a member of the Virginia legislature who campaigned for the adoption of the [[United States Bill of Rights]]. ==History== Mason County was created in 1841 out of portions of [[Tazewell County, Illinois|Tazewell]] and [[Menard County, Illinois|Menard]] counties. <gallery> File:Mason County 1841.png|Mason County at the time of its creation in 1841 </gallery> ==Geography== According to the [[U.S. Census Bureau]], the county has a total area of {{convert|563|sqmi}}, of which {{convert|539|sqmi}} is land and {{convert|24|sqmi}} (4.3%) is water.<ref name="census-density"/> Mason County is bounded on the south by the [[Sangamon River]], and on the west by the [[Illinois River]]. These rivers join at the southwest tip of the County. The soil covering much of Mason County is very sandy in composition. This was formed during the melting of the [[Wisconsin Glacier]] about 10,000 years before present. Meltwater from the glacier deposited large amounts of sand in a delta region near at the junction of the Sangamon and Illinois Rivers. The sandy soil does not hold water well, quickly exposing crops to drought conditions as the [[water table]] drops during periods of low precipitation. The soil is, however, very good for growing vegetables that are otherwise not common in Illinois. Modern irrigation has made this a highly productive agricultural area. A sand wetland on the Illinois River is managed by the [[U.S. Fish and Wildlife Service]] as the [[Chautauqua National Wildlife Refuge]]. ===Climate and weather=== {{climate chart |[[Havana, Illinois]] |14|32|1.85 |19|38|1.94 |30|50|3.02 |40|63|3.45 |51|74|4.43 |60|84|3.81 |64|88|3.87 |61|86|3.45 |52|80|3.21 |41|68|2.86 |30|51|3.26 |19|37|2.63 |float=right |units=imperial |clear=both |source=The Weather Channel<ref name="weather">{{cite web |url=http://www.weather.com/weather/wxclimatology/monthly/graph/USIL0521 |title=Monthly Averages for Havana, Illinois |accessdate=2011-01-27 |publisher=The Weather Channel }}</ref>}} In recent years, average temperatures in the county seat of Havana have ranged from a low of {{convert|14|°F}} in January to a high of {{convert|88|°F}} in July, although a record low of {{convert|-30|°F}} was recorded in January 1999 and a record high of {{convert|106|°F}} was recorded in July 1983.
