Overview and character

The county’s economy relies on agriculture, food processing, manufacturing, health care, and education, with a mix of small towns and suburban neighborhoods around Decatur.

History

Before Euro‑American settlement the area was inhabited by Indigenous peoples. European‑American settlement accelerated in the early 19th century as Illinois was organized and opened for farming. The county grew around transportation routes and the city of Decatur, which developed as a local trade and manufacturing center. The county name honors a prominent political figure from the early republic.

Economy and infrastructure

Agriculture has long been central: corn and soybeans dominate the surrounding countryside, while food processing and agribusiness firms provide local employment. Decatur hosts educational institutions and regional health centers that serve county residents. Transportation connections include regional highways, rail corridors and a municipal airport that support freight and travel.
