The book's checklist

  • Lower cost of livingEveryday prices run 4.9% below the U.S. average in the St. Louis metro area.
  • More house for the moneyA typical home costs 3.4 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 Weldon Spring 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 town5 public schools: 1 elementary, 2 middle and 2 other. No public high school in town: the nearest is Francis Howell Central High, about 3 miles away.
  • A hospital close byProgress West Hospital in Ofallon, about 2 miles away, has the nearest emergency room.
  • Within reach of a big citySt. Louis is about 23 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 Weldon Spring 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.

What kind of town

A suburb, not a stand-alone small town

Weldon Spring runs into the built-up area around St. Louis (Census Bureau, 2020 urban areas). We include suburbs under 20,000 people because some still feel like small towns, but daily life here is closer to the suburbs than to the towns Frank and Dave's book describes. Weigh it against towns farther out.

The book sorts small towns into six types. These labels come only from the numbers; take the quiz to see which type fits your family.

Home values and rents are what households told the Census Bureau across 2020 to 2024, so they trail today's market: county prices have moved up 21% since 2022. Everyday prices are the government's average for the St. Louis metro area, not Weldon Spring 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: Progress West Hospital, St. Peters, St. Louis.

St. Charles County is in a metro area of 1 million people or more (USDA rural-urban code 1, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
