Macon County comprises the Decatur, IL Metropolitan Statistical Area.
Macon County was formed on January 19, 1829 out of Shelby County. It was named for Nathaniel Macon, a Colonel in the Revolutionary War. Macon later served as senator from North Carolina until his resignation in 1828. In 1830, future US President Abraham Lincoln and his family moved to Macon County.
Macon County is primarily flat, as is most of the state and all of the surrounding counties, the result of geological activity during the Pleistocene epoch. During the Illinoian Stage of the Pleistocene, the Laurentide Ice Sheet covered about 85 percent of Illinois, including the Macon County area. The subsequent thaw of the region and retreat of the ice sheet left central Illinois with its present characteristic flat topography.
Because of its central location, Macon County is often referred to as "The Heart of Illinois."

In its early years Macon County favored the Democratic Party, voting for it in every election through 1856. Republican Abraham Lincoln won the county in his landmark 1860 election, and from then until the Great Depression Macon County became solidly Republican, only giving a narrow plurality to Woodrow Wilson in 1912 when the GOP was mortally divided by Theodore Roosevelt's splinter–party run.
The FDR-era New Deal saw the county turn Democratic again due to its strong industrial base, although Macon was a perfect bellwether between 1932 and 1996 apart from the Catholicism-influenced 1960 election and the 1988 election heavily influenced by a major Midwestern drought. Al Gore did narrowly hold the county in 2000 despite losing the election due to a razor-thin loss in Florida, but since then the county has trended Republican. Illinois-bred Barack Obama did win Macon County in his 2008 triumph, but was convincingly defeated by Mitt Romney in 2012, whilst in 2016 Hillary Clinton suffered the worst Democratic loss since George McGovern.
