The 2010s room

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.

Curator note: From ICWP 2015 white paper, Chapter 7, Section 1 (Figure 7-2-1-1), data end of 2014: computer household penetration 78.0%. Essentially unchanged from 2004 (77.5%) — PC penetration plateaued as smartphones displaced secondary PCs. Source: 2014 Communications Usage Trend Survey, MIC.
Source note: Annual white paper since 1973. English online summaries available 2001–2024. Key data: household penetration of mobile phones, PCs, fax, car navigation, broadband; internet users and penetration. Pre-2001 English summaries not available online (may be Japanese-only or print). Chapter PDFs downloaded for 2001 (ch.2), 2005 (ch.2), 2010 (ch.4), 2015 (ch.5).

All-types broadband availability was 100% (55.57 million). Fixed-line broadband subscriptions 36.80 million. Source: 2014 Communications Usage Trend Survey, MIC.

Confidence: D — Scholarly estimate
Curator note: The 2014 NSFIIE and the 2019 survey (renamed to National Survey of Family Income, Consumption and Wealth) do not publish English durable-goods summaries — the English pages link only to e-Stat statistical tables (Japanese interface). The NSFIIE 2009 figures shown above are the closest available English-language durable-goods data; the ICWP 2015 household penetration rates (mobile, smartphone, PC, broadband) fill part of the gap for the 2010s.
Source note: Quinquennial deep-dive survey since 1959. Publishes 'Summary of Results Concerning Major Durable Goods' with possession rates (% of households) and ownership quantities (per 1,000 households) for ~40 categories. English HTML summaries available for 1999, 2004, 2009. The 2014 and 2019 (renamed) surveys do not publish English durable-goods summaries — data only via e-Stat (Japanese). Main data tables are image-based (GIF) on HTML pages; numbers transcribed from narrative text.

Confidence: D — Scholarly estimate
Curator note: No item prices are in the archive for the 2010s, so hours-of-work-to-afford comparisons cannot be computed. The MLS wage (¥361,684/month, 2015) is the available wage reference. Under deflation, the affordability axis (hours-to-afford) would be the more reliable comparator than nominal-value ratios.
Source note: Monthly payroll survey of employment, wages (total cash earnings), and working hours. Long-term actual CSV (mls-long-term-actual.csv) covers 1960–2026 at industry level; all-industry (TL) total available from 1970. Data for 1955/1965 taken from scanned Japan Statistical Yearbook pages. 'Total cash earnings' includes regular pay (所定内給与) and special pay (特別に支給された給与).

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.
