Data catalog
Data Catalog
A transparent catalog of the public datasets, fixture snapshots, and computed signals used by Housing BuildDesignHub.
About this catalog
Housing BuildDesignHub production pages currently use source-attributed static fixtures. This catalog documents the fixture-backed data pipeline and the public datasets the system is structured around. It does not provide a public CSV/API download yet, and Housing BuildDesignHub does not claim ownership of or any official license on the upstream public datasets it cites.

Computed signals
Derived scores on city pages. Each signal lists its inputs and source dependencies. See methodology for formulas and weights.
Affordability
Higher score = relatively more affordable for typical income.
- Inputs
- Median household income (ACS) · Median gross rent (ACS)
- Sources
- Census ACS
Supply
Higher score = supply growing relative to existing stock.
- Inputs
- Trailing-12 building permits (BPS) · Housing units (ACS)
- Sources
- Census BPS · Census ACS
Price momentum
Higher score = stronger recent price appreciation.
- Inputs
- Home Price Index year-over-year change (FHFA)
- Sources
- FHFA HPI
Not a forward forecast.
Job market
Higher score = lower / improving unemployment.
- Inputs
- Unemployment rate (BLS LAUS) · 12-month unemployment trend (BLS LAUS)
- Sources
- BLS LAUS
Economic strength
Higher score = higher and growing per-capita income at metro level.
- Inputs
- Per-capita personal income (BEA) · Per-capita personal income growth (BEA)
- Sources
- BEA Regional
Climate risk
Lower exposure = higher score. Mapped at the city's primary county.
- Inputs
- FEMA National Risk Index composite + classification
- Sources
- FEMA NRI
County-level context, not property-level risk.
Overall score
Composite balanced reading across all signal categories.
- Inputs
- Weighted composite of the six signals above (see /methodology).
- Sources
- All six wired adapters
Coverage
The platform reports 100% required fixture coverage when every required fixture field exists for the current supported reports. That is a structural completeness signal — it does not mean the platform represents every real-world fact about a market.
Per-source freshness and stale-snapshot warnings are surfaced at /data-status on every deploy.
Public data exports
Each supported market is exposed as a read-only fixture profile in two formats: JSON (full object response) and CSV (one row per metric). All endpoints are static, do not call live APIs, and explicitly set liveData: false (JSON) or live_data=false (CSV column). See /api-docs for the response schema, column reference, examples, and caveats.
Bulk CSV — all markets
One row per market metric across every supported market; same columns as the per-market CSV.

Access and licensing
- Public exports are live in two formats. Each market exposes a fixture-backed JSON profile at
/api/markets/<market-id>and a one-row-per-metric CSV at/api/markets/<market-id>/csv. - DataDownload schema. City-page
DatasetJSON-LD references both the JSON and CSV endpoints viadistribution. - Machine-readable contract. /api/schema/market-profile serves JSON Schema (draft-07) for the JSON profile; /api/schema/market-csv describes the CSV column contract.
- Upstream licenses. Raw datasets cited above retain their own licenses, terms, and citation conventions — see each agency's landing page.
- No standalone Housing BuildDesignHub license claim. Fixture profiles are shown for transparency, not offered as a standalone downloadable dataset. /methodology acts as the current usage/license caveat page.
