History and origin

DeWitt County was created on March 1, 1839 from portions of neighboring counties. It was named for DeWitt Clinton, an influential early-19th-century governor of New York who was widely admired for his role in promoting canals and internal improvements. The county developed during the mid-1800s as settlers moved westward into Illinois, established farms, and organized local government and towns.

Economy, demographics and services

The county's economy remains anchored in agriculture, with corn and soybeans, livestock production, and services that support farming communities. Small manufacturing firms, retail businesses in Clinton, and public-sector employers contribute to local employment. Population density is low compared with urban counties; the 2010 census recorded 16,561 residents, and the county has continued to function as a small, close-knit community centered on township and municipal institutions.

Government, institutions and notable facts

Local government is organized around a county board, elected officials, and municipal administrations for towns such as the county seat. Public services include schools, libraries, health clinics and recreational facilities. Notable local sites often reflect the county's agricultural heritage and small-town character, and energy or manufacturing facilities near the seat have played roles in the local economy.
