The median family's century, on the record

A decade-by-decade museum of the median-income four-person family's lifestyle. Every fact carries its source card and confidence tier; where the record is silent, the museum shows the gap.

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.

The record at a glance

Every room × every case, counted. The sliver under each count is the tier mix (green A to grey D — see the legend); an ember line marks documented silences the museum renders instead of guessing.

Counting rule: N sourced facts, +M exhibits computed at build from sourced inputs. A "gap" is a curated, documented silence — never a value. 95 sources stand behind every cell.

Ways in

The wings

Each country is its own wing: its rooms interlink, and its exhibits never borrow another country's record. A wing without curator's routes shows bare stages over complete, sourced ledgers.

Docent tours

Short curated walks through the evidence — every figure bound to its exhibit.

Confidence & flags

A — official statistical series
B — official microdata, computed by this project
C — reconstructed from period surveys
D — scholarly estimate
Gap — no reliable record; shown as the gap it is

Reading the atlas

Provenance is in the scan-line: every exhibit's row names its value, confidence tier, the population actually measured, and the source record. Chart points and stage glyphs open the same record.

Rising series draw in petrol, falling in ember. Absent technology isn't drawn — a bare house says more than ghosts.
