Hampshire School District

It never has a ZIP Code to itself

The counts below come from the census blocks assigned to Hampshire, grouped by the ZIP Code area each block falls in. The Census Bureau publishes the blocks; the grouping is computed here, and it is the only place these particular numbers exist.

• Homes inside the boundary5,548
• Residents12,110
• ZIP Code areas it reaches8
• Where it is the only district0
• Where it shares with another district7
• Where it holds under half a percent1

• Homes per square mile43

The ZIP Code areas it reaches

The spread is the thing to notice. In 01012 this district holds 100% of the homes; in 01026 it holds 2 homes, under half a percent. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

• ZIP Code 01012 · Chesterfield, Massachusetts100% of the homes
• ZIP Code 01032 · Goshen, Massachusetts100% of the homes
• ZIP Code 01084 · Chesterfield, Massachusetts100% of the homes
• ZIP Code 01073 · Southampton, Massachusetts94% of the homes
• ZIP Code 01096 · Williamsburg, Massachusetts93% of the homes
• ZIP Code 01039 · Williamsburg, Massachusetts79% of the homes
• ZIP Code 01027 · Easthampton Town, Massachusetts8.7% of the homes
• ZIP Code 01026 · Cummington, Massachusetts2 homes, under half a percent

What one name misses, and what changes later

Hampshire is the largest district in 3 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 396 of the 4,495 homes those areas hold. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.

ZIP Code 01073 · Southampton, Massachusetts is a two-district area: 2,394 of its 2,551 homes are inside Hampshire, and the other 157 homes are with Easthampton. Which one an address belongs to is settled by the street, not by the five digits.

Hampshire holds 549 of the 699 homes in ZIP Code 01039 · Williamsburg, Massachusetts, so its name is right for most of the area and wrong for the rest: 150 homes with Frontier and Hatfield.

In ZIP Code 01096 · Williamsburg, Massachusetts the split runs 1,156 to 89 and the larger part is Hampshire's: the rest is 89 homes with Frontier and Mohawk Trail School District.

Hampshire is not the name anyone would give for ZIP Code 01027 · Easthampton Town, Massachusetts — Easthampton leads it — and Hampshire holds 747 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 01012 · Chesterfield, Massachusetts is close to being two districts in equal parts: Hampshire holds 318 of its 318 homes and Chesterfield-Goshen leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

ZIP Code 01032 · Goshen, Massachusetts is another area where Hampshire is present without being the answer: 292 of its 292 homes, behind Chesterfield-Goshen.

The elementary districts that feed it

Students arrive at Hampshire from 6 districts that run the lower grades on the same ground — Southampton, which sends 41%, Chesterfield-Goshen, which sends 21% and Williamsburg, which sends 19%. Each of those addresses therefore belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

• Southampton School District41% of Hampshire's homes come from here
• Chesterfield-Goshen School District21% of Hampshire's homes come from here
• Williamsburg School District19% of Hampshire's homes come from here
• Easthampton School District15% of Hampshire's homes come from here
• Whately School District2.0% of Hampshire's homes come from here
• Conway School District1.2% of Hampshire's homes come from here

The names in this list are exact: the federal file gives the district of each band for every census block. The percentages are not. They spread each shared ZIP Code area's homes across the other band in proportion to the share each district holds there, because the file names the two districts of a block and not how a household moves between them. Read them as the size of the crossing, not as a count of houses.

Who it shares ZIP Codes with

Hampshire shares ZIP Code areas with 10 different districts. The most frequent are Chesterfield-Goshen, Easthampton, Frontier and Williamsburg. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

What to do next

Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.

A ZIP Code is a set of mail delivery routes, not a boundary: in 7 of the 8 ZIP Code areas Hampshire reaches, at least one other district holds a real share of the homes as well, and the line between them runs along streets. Only the district can say which side of that line an address is on.

This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.

If a house purchase depends on the answer, ask the district itself for written confirmation of that exact address. A listing is not a district record, and neither is this page.

What this cannot tell you

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.

A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.

A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.

A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.

Where these numbers come from

School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.

The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.

Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
