Port Monmouth, New Jersey

Port Monmouth is an unincorporated community of about 3,000 people in Monmouth County, New Jersey, in the New York area. It has no city government of its own: local services come from the county, or in some states from the town or township. A typical home costs about 4.3 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, New York, is about 18 miles away as the crow flies.

The book's checklist

  • Lower cost of livingEveryday prices run 12.6% above the U.S. average in the New York-Newark-Jersey City metro area.
  • More house for the moneyA typical home costs 4.3 years of the typical household's income here. Across the U.S. it's 4.1.
  • A safer neighborhoodThe FBI doesn't publish crime figures for unincorporated communities. Call the county sheriff's office (or the town or township police, where there is one) and ask what calls they get most.
  • Schools in town4 public schools: 1 elementary, 1 middle, 1 high school and 1 other.
  • A hospital close byBayshore Medical Center in Holmdel, about 5 miles away, has the nearest emergency room.
  • Within reach of a big cityNew York is about 18 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 Port Monmouth 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

Port Monmouth runs into the built-up area around New York (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 28% since 2022. Everyday prices are the government's average for the New York-Newark-Jersey City metro area, not Port Monmouth 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: Bayshore Medical Center, Perth Amboy, New York.

Monmouth 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).
