Data
Rights and attribution
How sources are licensed, which are restricted, and the credit each one requires.
Being able to download a dataset does not mean it may be redistributed. Every source Cadastre imports is checked against its publisher's terms before its figures are shown, and the result is recorded where every screen, report and export asks: a source's own declaration in the code (its licence, and whether it is restricted) and, for sources with conditions or unsettled terms, a row in the sources register. This page summarises that register; each dataset's page has the details.
How sources are licensed
Most of Cadastre's datasets are works of the U.S. federal government, which are in the public domain: the Census Bureau, the Bureau of Labor Statistics, the Bureau of Economic Analysis, the Energy Information Administration, FEMA, the EPA, the Department of Transportation and CDC. Some publishers attach conditions even to public-domain data (CDC asks for a credit and a disclaimer). OpenStreetMap is licensed under the Open Database License, which requires a credit and has share-alike terms.
For each source it holds, the register records a licence label and the uses it allows (a federal work without a register row is judged by its licence alone):
| Use | What it allows |
|---|---|
evaluation | Reviewing the data internally before deciding whether to use it |
internal | Internal use |
public_display | Showing figures from the source in the app and its reports |
derived_analytics | Computing figures from it: metro rollups, scores, rankings |
redistribution | Passing the data on to others |
bulk_export | Including its figures in a file a client takes away (CSV, Excel) |
public_geometry | Serving the source's own geometry publicly, such as map tiles |
A use the licence does not support cannot be granted: redistribution, bulk export and public geometry need an open licence.
Restricted sources
A restricted source is never redistributed. Its rows may be held, flagged, so the decision can be revisited, but no metric read sees them: no screen, criterion, ranking, report or export shows its values, and the API will not serve them. Its docs page describes it so you know it was reviewed, and says why it is restricted.
| Dataset | Why it is restricted |
|---|---|
| County Health Rankings | Its terms allow personal or non-profit use only; commercial use needs CHR&R's written consent, which Cadastre does not have. It is described here so you know it was reviewed, but its values reach no screen, report or export, and the API will not serve them. |
| HIFLD transmission lines via Esri Living Atlas archive | Its licence is unresolved: the federal record describes a U.S. government work, but the only live copy is republished under the Esri Master License Agreement. Until that is settled it is used for evaluation only: its values reach no screen, report or export, and the API will not serve them. The OpenStreetMap source answers the same questions. |
Attribution
Where a source requires a credit, Cadastre prints it on every page and in every file that shows the source's figures: the report's data sources page (web, PDF, PowerPoint), the CSV and Excel sources, and the API's responses when it launches. If you use figures from Cadastre, carry the same credit.

Every other available source is a U.S. federal government work that asks for no credit line beyond naming it. Cite the publisher and the product, as named on each dataset page.
CDC. CDC's terms for agency materials (opens in a new tab) also ask that the content not be changed (county values are kept as CDC published them; metro values are labelled as Cadastre's aggregates), that the data be stated to be available at no charge, that links to CDC open in a new window, and that no CDC or HHS logo be used. CDC's overdose rates come from death records, so the NCHS Data User Agreement (opens in a new tab) also applies: statistical use only, no attempt to identify any person, and no linking with individually identifiable data.
OpenStreetMap. The transmission-line measures derived from OpenStreetMap are kept separate from every other source. The line data itself is offered under the ODbL on the Open data page.
Your use of Cadastre
Your use of Cadastre, its data and its API is governed by the Terms of Service. What you may do with what the API returns, and the credit it must carry, is in API, MCP and developer access.
