Mason County is a county in the U.S. state of Illinois. According to the 2010 census, it had a population of 14,666. Its county seat is Havana. 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.
The soil covering much of Mason County is very sandy. This was formed during the melting of the Wisconsin Glacier about 10,000 years ago. 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. However, the soil is very good for growing vegetables that are otherwise not common in Illinois. Modern irrigation has made this a highly productive agricultural area.

Although it voted for the Whig Party in the three elections from 1840 to 1848, Mason County was to be solidly Democratic for the next sixty to seventy years due to its anti-Yankee German-American heritage. It was not until the 1920 election when bitter resentment was felt by German-Americans at Woodrow Wilson’s postwar policies that Mason supported a GOP candidate.
In the following eighty years, Mason was a Republican-leaning swing county, although isolationist sentiment did cause it to vote narrowly for Wendell Willkie in 1940 and more convincingly for Thomas E. Dewey in 1944. The past decade or so has seen Mason turn solidly Republican due to opposition to the Democratic Party’s social liberalism and concern over the lack of employment and other economic opportunities in the “Rust Belt” – whose edge Mason County lies on.
