North Carolina sources & data layers

Every layer in districtry North Carolina, and exactly where its data comes from.

← Back to the map 🧩 What data is missing?

This app is a reader over other people's data. It draws no boundary of its own and names no officeholder it cannot cite, so the useful question about any answer it gives is who published this, and when. That is what this page is for: the publishers the app credits as a whole, then one row per layer naming the source behind that layer specifically.

Not for legal or official use. Boundary and roster data come from public sources that explicitly disclaim legal precision. Always confirm district assignments and officeholders with the relevant government office before relying on them for anything official.

Data last verified: September 29, 2026

Where a source publishes nothing, the app says so rather than guessing — the missing-data panel on the map is the standing list of what nobody publishes yet, and what would close each gap.

This page says where each answer comes from today.

Who publishes the data

The upstream publishers this app depends on, across all layers. Per-layer provenance is in the matrix below.

The layer matrix

15 layers — 5 political and legislative, 2 public safety, 2 schools, 6 geography and amenities. Each row names the publisher the boundary comes from, where the names on the card come from, and the ground the layer actually answers on — outside that ground the layer hides itself rather than guessing.

Political & legislative 5 layers

Districts that elect somebody — from your ward to your seat in Congress.

LayerWhat it answersBoundary sourceWho it namesWhere it applies
U.S. Houseus-house The U.S. House district covering the point, and the representative holding it. congress-roster.json, rebuilt weekly by CI from the public-domain unitedstates/congress-legislators dataset — including each member's district office and Washington office. North Carolina — statewide, all 14 districts.
NC Senate Districtnc-senate The North Carolina Senate district covering the point, and the senator holding it. nc-senate-members.json, rebuilt weekly by CI from the Open States current-people export for North Carolina (name, party, e-mail, links). What the General Assembly publishes beyond that is recorded in nc/WATCH.md rather than assumed. North Carolina — statewide, all 50 districts.
NC House Districtnc-house The North Carolina House district covering the point, and the representative holding it. nc-house-members.json, rebuilt weekly by CI from the Open States current-people export for North Carolina. North Carolina — statewide, all 120 districts.
Tribal Governmenttribal-government Whether this address is on tribal land, and which nation's government answers for it — North Carolina has 2 such areas, both the Eastern Band of Cherokee Indians'. Nobody yet: the Eastern Band's site could not be read from where this project is built, and the card says so. The communities the Census draws on the land are named on the card. The government, its seat and its website come from the Bureau of Indian Affairs' tribal leaders directory (data/bia-tribal-governments.json); the land is joined to the government by this project's own data/tribal-government-join.json. Western North Carolina — the Qualla Boundary and its trust land. Most points in the state are on no tribal land.
City Council Districtcity-ward The city council district or ward containing the point, in the 17 North Carolina cities above 25,000 people that elect council members by district or ward, and the member for it. The member for each district, from the same city council roster the City or Town card reads (nc/data/app/nc-city-councils.json), written down from each city's own pages (Raleigh's from the State Board of Elections' results) and proved against them by nc/scripts/build_nc_city_councils.py. Which seats a district elects was read from each city's own pages. Its check holds every drawn district to a seat its voters elect and every such seat to a drawn district. Gastonia's members for Wards 3, 4 and 6 were elected by the whole city, and the card says so. The 17 North Carolina cities above 25,000 people that elect council members by district or ward: Cary, Charlotte, Fayetteville, Gastonia, Goldsboro, Greensboro, Greenville, High Point, Jacksonville, Mooresville, New Bern, Raleigh, Rocky Mount, Sanford, Statesville, Wilson and Winston-Salem. Durham, Concord, Hickory and Morrisville tie seats to wards or districts and elect every one by the whole city, so a district there would elect no one of its own. Ground inside a city's Census outline that its map leaves out lies in no district here.

Public safety 2 layers

Who answers a call at this address, and where they answer it from.

LayerWhat it answersBoundary sourceWho it namesWhere it applies
Police Stationpolice-station The three nearest police stations to the point, by straight-line distance, with each one's address. NO OFFICEHOLDER, AND NONE IS MISSING: a police station is a facility, not an elected district. Nobody is elected from one. North Carolina — plus the border strip its envelope necessarily includes. A BUILDING, NOT A JURISDICTION: which agency answers at a given point is a service-area question this instance has not been researched for, so the card says where the nearest are and never who serves you. Nearest-three is a proximity fact, so for a reader near the state line the nearest one really may be in Virginia or South Carolina, and the card's intro says these are straight-line distances.
Fire & EMS Stationfire-station The three nearest fire and EMS stations to the point, by straight-line distance, with each one's address. NO OFFICEHOLDER, AND NONE IS MISSING: a fire and EMS station is a facility, not an elected district. Nobody is elected from one. North Carolina — plus the border strip its envelope necessarily includes. A BUILDING, NOT A JURISDICTION: which agency answers at a given point is a service-area question this instance has not been researched for, so the card says where the nearest are and never who serves you. Nearest-three is a proximity fact, so for a reader near the state line the nearest one really may be in Virginia or South Carolina, and the card's intro says these are straight-line distances.

Schools 2 layers

The district, the attendance zone, and the schools nearest the point.

LayerWhat it answersBoundary sourceWho it namesWhere it applies
School Districtschool-district-unified The public school district covering the point. NO OFFICEHOLDER, AND THE CARD NAMES THE DISTRICT ONLY. North Carolina's boards of education are elected, and no statewide roster of their members was found in this pass — recorded as a gap rather than left unstated. North Carolina — statewide. The label carries no qualifier because there is nothing to distinguish it from: the elementary-only and secondary-only tilings TIGERweb serves for other states are EMPTY in North Carolina (0 features each, measured 2026-09-29), so one tiling ships where Illinois ships three.
School Board Districtschool-board-district The election district of a North Carolina school board that elects members by district, and the school district whose board it is. Where one election's ballots in a precinct carried two of a board's districts, both are named; where different elections put different districts on the ballot, each election's are named and none is chosen; where the results place no current district seat, the card says so. NO MEMBER IS NAMED YET. The results name each contest's winner, but a board fills a vacancy by appointment, which no results file records, and the seats on the November 3, 2026 ballot stay with the members serving now until that election's winners take office. Matching the winners to the members serving now has not been done, so the card names no one rather than guessing — recorded as gap nc-school-board-members. The card links each board's school district website instead: the address that the National Center for Education Statistics' Common Core of Data district directory for the 2025-26 school year gives, kept where it answered with a page when the file was built, which all 38 did on 2026-10-17. The 38 North Carolina school districts whose boards elect members by district, measured 2026-10-17 from the results as the boards whose district seats are each voted on in only part of the school district: Alexander, Anson, Beaufort, Bladen, Buncombe, Caswell, Charlotte-Mecklenburg, Craven, Cumberland, Duplin, Durham, Edenton-Chowan, Edgecombe, Forsyth, Franklin, Granville, Guilford, Harnett, Hickory City, Iredell-Statesville, Lenoir, Lexington City, Madison, Martin, Montgomery, Nash-Rocky Mount, Newton-Conover City, Pamlico, Pitt, Robeson, Rockingham, Union, Vance, Wake, Watauga, Wayne, Whiteville City and Wilson. 45 boards are elected at large, and 32 more label seats by district while every precinct votes on each of them; neither kind has districts to draw, and the empty card says so.

Geography & amenities 6 layers

The boundaries that place an address without electing anyone, plus the nearest public services.

LayerWhat it answersBoundary sourceWho it namesWhere it applies
Countycounty Which county contains the point, who won each seat on its board of commissioners, and who sits on the board of the soil and water conservation district that covers it. Every county's board of commissioners, each seat named for the winner of its most recent election in the North Carolina State Board of Elections' results (the 2022 and 2024 generals), read with the State Board's candidate filing lists for each seat's term and dated to that election; rebuilt weekly by nc/scripts/build_nc_county_commissioners.py. A winner is not a sitting member: a board fills a vacancy by appointment, which no result records, and the card says so. A seat the 2026 filing list shows has changed hands names nobody and says why. Three limited-voting counties' seat counts were read from the counties' own board pages; Tyrrell's could not be, so its board names nobody. Every seat in the county is listed because no publisher draws commissioner districts (G.S. 153A-22(f) keeps them as written descriptions in each clerk's office). The card also names the supervisors of the county's soil and water conservation district, from the Division of Soil and Water Conservation's District Directory, one PDF printed from the division's database, read by nc/scripts/build_nc_conservation_boards.py: each supervisor's office on the board, whether the seat is elected or appointed, and the term; re-read quarterly and after each November election (nc/WATCH.md). A seat the directory lists with no name is shown that way and never as a vacancy, and the Albemarle district's supervisors are listed county by county, as the directory lists them. North Carolina — statewide, all 100 counties.
Townshipcounty-subdivision The township containing the point. NO OFFICEHOLDER. A North Carolina township is a census and historical unit with no governing board of its own, unlike Illinois's, so the card is identity-only and says so. MEASURED CAVEAT: at least two counties (Gaston, Hyde) name their COMMISSIONER districts after townships in their certified returns, so a township can carry an electoral function even where it has no government — recorded in nc/WATCH.md rather than generalised from two counties. North Carolina — statewide.
ZIP Codezip-code The ZIP Code Tabulation Area covering the point — the Census Bureau's areal approximation of the USPS delivery routes sharing a ZIP code, not a postal boundary. NO OFFICEHOLDER, AND NONE IS MISSING: a ZIP code is a mail-routing convenience, not a unit of government, so nobody is elected from one. The card says what the boundary actually is rather than leaving a reader to assume it means more. North Carolina. A ZCTA is kept where it overlaps the state, so a click in Virginia, Tennessee, Georgia or South Carolina gets the layer's own empty note rather than a false silence or a neighbouring state's ZIP code.
Voting Precinctvoting-precinct The voting precinct containing the point — where a reader votes and how their ballots are reported. NO OFFICEHOLDER, and none is missing. A precinct elects nobody — it is an election-administration unit, not a district with a representative — so the card says that rather than leaving a reader to wonder which name is absent. North Carolina — statewide.
City or Townmunicipality The city or town containing the point, if any. In the 42 cities and towns above 25,000 people, the mayor and every council member, alderman or commissioner, written down from each city's own pages and proved against those pages by nc/scripts/build_nc_city_councils.py, which fails when a name is no longer on the page it cites (nc/data/app/nc-city-councils.json). Where the page a seat cites prints an e-mail address or a telephone number beside that member alone, the card shows it, and the build proves it on that page in the same way; a line or mailbox the page gives the office or several members is not shown, and no street address is. Raleigh's and Matthews's names are the candidates with the most votes in the State Board of Elections' results, because both websites answer this app with a managed challenge, and the card says so. Each seat says whether its district's own voters or the whole city elect it, read from each city's own pages, because nothing the state publishes records it. North Carolina's other 510 cities, towns and villages name nobody yet, recorded as gap nc-municipal-officeholders. North Carolina — statewide. A point outside every incorporated place is unincorporated, which the card states.
Post Officepost-office The three nearest post offices to the point, by straight-line distance, with each one's address. NO OFFICEHOLDER, AND NONE IS MISSING: a post office is a facility, not an elected district. Nobody is elected from one. North Carolina — plus the border strip its envelope necessarily includes. A BUILDING, NOT A JURISDICTION: which agency answers at a given point is a service-area question this instance has not been researched for, so the card says where the nearest are and never who serves you. Nearest-three is a proximity fact, so for a reader near the state line the nearest one really may be in Virginia or South Carolina, and the card's intro says these are straight-line distances.
