# Cadastre

> Cadastre is a data source for real-estate and site-selection data (not listings): public market, labor, demographic, infrastructure, hazard and health datasets for every U.S. metro area, with their sources, licences and methods documented.

These docs describe every dataset Cadastre holds, how metro values are computed, and the rights and credit each source carries. Pages describe data; they do not publish data values. The read-only API and a remote MCP server are coming soon.

- [Dataset: CDC Mapping Injury, Overdose, and Violence](https://getcadastre.com/docs/datasets/cdc-overdose.md): CDC's county drug overdose death rates per 100,000 residents from the Mapping Injury, Overdose, and Violence county file, built from NCHS National Vital Statistics System death records by county of residence.
- [Dataset: BLS LAUS](https://getcadastre.com/docs/datasets/bls-unemployment.md): Local Area Unemployment Statistics (LAUS): the unemployment rate for every metro and micro area, as the latest full-year annual average, with the latest published month kept as a separate measure.
- [Dataset: BLS QCEW](https://getcadastre.com/docs/datasets/bls-qcew.md): The Quarterly Census of Employment and Wages: annual-average private-sector employment, establishments and location quotients by county and NAICS industry, for a curated list of manufacturing, logistics and related industries, so a question like "does this market have an aerospace base?" can be screened.
- [Dataset: BEA GDP](https://getcadastre.com/docs/datasets/bea-gdp.md): BEA regional GDP: total GDP, manufacturing GDP and the manufacturing share of GDP.
- [Dataset: BLS LAUS history](https://getcadastre.com/docs/datasets/bls-laus-history.md): Trend measures from the LAUS annual history: labor-force and resident-employment growth, the unemployment rise in the Great Recession and in 2020, and the ten-year average and volatility of the unemployment rate.
- [Dataset: BLS QCEW history](https://getcadastre.com/docs/datasets/bls-qcew-history.md): Trend measures from QCEW annual averages: private-sector and manufacturing employment growth, nominal average-pay growth, the latest average annual pay and the change in the manufacturing location quotient.

A new major source in a non-attainment area needs emission offsets and the strictest controls, which makes permitting slower and dearer.
- [Dataset: HIFLD transmission lines via Esri Living Atlas archive](https://getcadastre.com/docs/datasets/hifld-transmission-lines.md): Reported electric transmission lines from DHS's Homeland Infrastructure Foundation-Level Data (HIFLD), through Esri's archived republication, and five metro measures of line length and voltage.
