Pemi-Baker Regional School District

10,556 homes hold 19,018 residents, about 1.8 people each. Where households are small, a district's share of the homes overstates its share of the children, and this page counts homes.

What one name misses, and what changes later

Pemi-Baker Regional is the largest district in 5 ZIP Code areas. Answer with its name alone and the answer misses 592 of the 7,635 homes those areas hold — though in 3 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Pemi-Baker Regional is one of 4 districts the file names for ZIP Code 03266 · Dorchester, New Hampshire at that level. It holds 922 of the 1,318 homes there; the rest is 396 homes with Mascoma Valley Regional, Unnamed district 3399983 and Ellsworth. One name for that area is not a simplification, it is a different answer for 396 of the homes in it.

ZIP Code 03264 · Plymouth, New Hampshire is a two-district area: 2,309 of its 2,505 homes are inside Pemi-Baker Regional, and the other 196 homes are with Unnamed district 3399983. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 03245 · Holderness, New Hampshire the single-name answer is the true one: Pemi-Baker Regional holds all 1,435 homes counted there, and no other district holds a share worth naming.

ZIP Code 03282 · Wentworth, New Hampshire is another area where one name covers everything — 503 homes, all of them inside Pemi-Baker Regional.

Pemi-Baker Regional reaches into ZIP Code 03223 · Campton, New Hampshire with 2,161 of its 2,232 homes; 3 districts there hold a real share of it, and Campton leads them. The familiar answer for that area is one of the others, and it is wrong for those 2,161 homes.

ZIP Code 03217 · Ashland, New Hampshire is close to being two districts in equal parts: Pemi-Baker Regional holds 1,352 of its 1,352 homes and Ashland leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

The elementary districts that feed it

Students arrive at Pemi-Baker Regional from 6 districts that run the lower grades on the same ground — Plymouth, which sends 20%, Campton, which sends 20% and Thornton, which sends 18%. 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.

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.

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 7 ZIP Code areas Pemi-Baker Regional 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.
