The corpus as a citable dataset
The museum's fact base is available as deterministic JSON and CSV exports. They are projections of the gated corpus, not a second source of truth.
The versioned record includes room metadata, every authored fact and all structured values, the computed results and operand ids for derived facts, the source register, and the assumption ledger.
A flat projection with the fact id, decade, panel, display value, structured quantity, unit, tier, source id, and short citation. Cells that could be interpreted as formulas are prefixed with an apostrophe. For exact, unmodified CSV values, use the raw CSV projection; JSON remains the canonical machine-readable record.
What the record means
The composite family Each room is a statistical composite, assembled from separate distributions with separate sources. The family at the median income did not also have the median house, the median car, and the median diet. No single family described here ever existed; each fact tells you, in its provenance drawer, which real population it was measured from.
Confidence tiers
Official statistical series.
Official microdata, computed by this project.
Reconstructed from period surveys.
Scholarly estimate.
How to cite
For a number, cite the primary source named by its
source in JSON (or source_id in CSV), then cite the
vitrine corpus for the compilation and tier assignment. The repository's
CITATION.cff is the corpus citation;
the exporter software is separately MIT-licensed. The corpus and rendered site
are licensed CC BY-SA 4.0.
This export contains aggregate facts and citations only;
underlying source material keeps the terms stated on its source record. The
full series observations included in corpus.json make computed
derivations reproducible without republishing raw source files.
