A check means Deerfield 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
Deerfield runs into the built-up area around Chicago (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 25% since 2022. Everyday prices are the government's average for the Chicago-Naperville-Elgin metro area, not Deerfield alone. Check current listings before you budget.
