What kind of town

A suburb, not a stand-alone small town

Allentown runs into the built-up area around Trenton (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.

Everyday prices are the government's average for the New York-Newark-Jersey City metro area, not Allentown alone. Check current listings before you budget.
