Overview

Understanding ZIP code 01031

ZIP code 01031 is assigned to Gilbertville, MA, and falls within Worcester County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 1,715 people live inside it.

At 255 residents per square mile spread over 6.733 square miles, 01031 reads as a small-town area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings run below the national median. At $58,125, 01031 sits in the lower half, ahead of 29% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Living here

What life in Gilbertville looks like

Housing in 01031 costs close to the national median. A typical home is valued at $237,700 against a US median of $207,500, and median gross rent runs $1,164 a month. The split between owning and renting is fairly even at 52.2% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by detached single-family houses, which account for 49.6% of housing units here. The median construction year is 1938, making the housing here largely pre-war.

The population skews younger than the country as a whole, with a median age of 35.9 against 42 nationally. The average household holds 2.46 people, and 65.0% are family households.

Getting to work takes 31.3 minutes on average one way. The dominant mode is drove alone at 69.3% of workers.

Where to stay

Where to stay in Gilbertville, MA

Gilbertville is a smaller community, so options inside 01031 may be limited to a handful of independent inns, motels or bed-and-breakfast properties. Travellers often widen the search to the surrounding area, where the choice is greater and prices are usually competitive.

Median rent in 01031 is $1,164 a month, which sits in the middle of the national range; accommodation pricing locally tends to be similarly mid-market. For reference, Boston, MA is about 57.9 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses

What ZIP code 01031 is used for

Beyond addressing mail, 01031 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 01031 offers a compact profile of Gilbertville: 1,715 residents, a median household income of $58,125, 22.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 2.2%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 01031 may cover parts of several distinct areas, and a single neighbourhood in Gilbertville may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.

Median gross rent in 01031 is $1,164 a month, according to the American Community Survey. Gross rent includes contract rent plus the estimated cost of utilities and fuels, so it is closer to what a tenant actually pays than a headline rent figure. Of 697 occupied homes here, 333 are rented.

Accommodation in and around Gilbertville, MA ranges with the character of the area. See the 'Where to stay' section on this page for local context, and use the live search there for current availability and pricing.
Does 01031 cover more than one city or county?
This page lists Gilbertville as the primary place and Worcester County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 01031 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
