What it’s like
The place. Old Monroe is a very small city in Lincoln County, Missouri, home to far fewer people than most American towns. Homes here are valued well below what a typical buyer might expect in many parts of the country, and the share of residents living below the poverty line is low. Winters are cold, with January the chilliest month, and snow falls most winters. Summers are warm to hot, with July the warmest month, and rain and melted snow arrive steadily through the year.
Work. Residents work mostly in schools, hospitals and social care, the building trades, manufacturing and shops. The commute is a moderate one, typical of a small town where many people drive to jobs elsewhere in the county. Among the largest workplaces across Lincoln County are Toyota Motor Manufacturing Missouri, which casts aluminum, the Troy R-III Schools district and Daddy Ray's, a bakery products maker. Few adults here hold a four-year degree, and unemployment across the county has eased a little over the past year.
Things to do. Several creeks are a short drive away, including Bobs Creek, Birkhead Branch and Big Creek, for quiet time near the water. A longer drive brings you to Cuivre River State Park, a protected area, and Pere Marquette State Park, another protected area along the Illinois River. For a day out with visitors, Mid America Adventure is an amusement park a longer drive away.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Old Monroe’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Lincoln County and the St. Louis, MO-IL metro.
