Louisville, Illinois

Louisville is a small town of about 1,100 people in Clay County, Illinois. It's the county seat. It has lost about 3% of its people since 2020. A typical home costs about 2 years of the typical household's income, compared with 4.1 across the U.S. The nearest metro area of about a million people or more, St. Louis, is about 94 miles away as the crow flies.

The book's checklist

  • Lower cost of livingEveryday prices run 12.6% below the U.S. average in the parts of Illinois outside metro areas.
  • More house for the moneyA typical home costs 2 years of the typical household's income here. Across the U.S. it's 4.1.
  • A safer neighborhoodThe FBI has no 2025 figures for Louisville itself. Many small towns are patrolled by the county sheriff, so call the sheriff's office and ask what calls they get most.
  • Schools in town2 public schools: 1 elementary and 1 high school.
  • A hospital close byClay County Hospital in Flora, about 6 miles away, has the nearest emergency room.
  • Within reach of a big citySt. Louis is about 94 miles away as the crow flies. The book suggests staying within about 60 miles if you'll miss big-city sports, concerts and theater.

A check means Louisville meets the rule of thumb from Frank and Dave's book. An empty box isn't a deal breaker: it's something to weigh for your family. A question mark means there isn't enough data.

Everyday prices are the government's average for the parts of Illinois outside metro areas, not Louisville alone. Check current listings before you budget.

Getting around

Straight-line miles. The road is always longer, and as the book says, an interstate at 70 is a different trip from a farm road at 45. Check the real drive: Clay County Hospital, Evansville, St. Louis.

Clay County is outside any metro area, with fewer than 5,000 people in its towns, not next to a metro area (USDA rural-urban code 9, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
