Cumberland Regional School District

New Jersey · runs grade 9 through grade 12

There is no ZIP Code area where Cumberland Regional is the only school district serving the homes. It holds a real share in 8 of them and shares every one, with 15 different districts in total. A lookup that returns a single district name for any of those ZIP Codes is guessing which side of a line an address falls on.

It never has a ZIP Code to itself

The counts below come from the census blocks assigned to Cumberland Regional, 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.

The ZIP Code areas it reaches

The spread is the thing to notice. In 08323 this district holds 100% of the homes; in 08318 it holds 1.7% of the homes. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

The areas it leads without holding most of the homes

Cumberland Regional is the largest district in 5 ZIP Code areas. Answer with its name alone and the answer misses 7,938 of the 16,463 homes those areas hold — though in 4 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Cumberland Regional is the largest name in ZIP Code 08302 · Bridgeton, New Jersey and still holds a minority of it: 7,795 of 15,733 homes. The other 7,938 homes are 7,932 with Bridgeton City, Alloway Township and Quinton Township; 6 in a district too small to name here. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

In ZIP Code 08320 · Fairfield, New Jersey the single-name answer is the true one: Cumberland Regional holds all 1 home counted there, and no other district holds a share worth naming.

ZIP Code 08323 · Othello, New Jersey is another area where one name covers everything — 364 homes, all of them inside Cumberland Regional.

Cumberland Regional is not the name anyone would give for ZIP Code 08332 · Millville, New Jersey — Millville City leads it — and Cumberland Regional holds 515 homes there all the same. Answer that area with one name and that is what it is wrong about.

ZIP Code 08318 · Olivet, New Jersey is another area where Cumberland Regional is present without being the answer: 79 of its 4,731 homes, behind Pittsgrove Township.

The elementary districts that feed it

Students arrive at Cumberland Regional from 6 districts that run the lower grades on the same ground — Bridgeton City, which sends 39%, Upper Deerfield Township, which sends 16% and Hopewell Township, which sends 12%. 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.

  • Bridgeton City School District39% of Cumberland Regional's homes come from here
  • Upper Deerfield Township School District16% of Cumberland Regional's homes come from here
  • Hopewell Township School District12% of Cumberland Regional's homes come from here

  • Unnamed district 34803717.1% of Cumberland Regional's homes come from here
  • Deerfield Township School District5.6% of Cumberland Regional'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

Cumberland Regional shares ZIP Code areas with 15 different districts. The most frequent are Fairfield Township, Deerfield Township, Alloway Township and Hopewell Township. 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.

Where this district sits

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 8 of the 8 ZIP Code areas Cumberland 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.
