An atlas of ordinary life
The rooms hold snapshots; the plates follow change. Its exhibits are arranged around four questions rather than one long register of charts. Every mark still opens the sourced record behind it, and every silence in the record remains visible.
Plate I · 7 exhibits
The household
Who made up the family, and how long did life last?
Population records describe the household from the outside: its size, its prevalence, and the health conditions surrounding it. The gaps show where the national series had not yet learned to count.
Life expectancy at birthyears (all races, both sexes) 7 of 13 rooms charted
Infant mortalitydeaths under age 1 per 1,000 live births 9 of 13 rooms charted
The mortality revolution: heart disease, cancer, strokeage-adjusted deaths per 100,000 population 9 of 13 rooms charted
Cancer 5-year relative survival% surviving 5 years after diagnosis (SEER) 7 of 13 rooms charted
People in poverty% below the official poverty line 7 of 13 rooms charted
Average family sizepersons per family 10 of 13 rooms charted
Number of familiesfamilies in the United States 9 of 13 rooms charted

The threshold
When did shelter become infrastructure?
Tenure, plumbing, cooling, mobility, and floor area entered the record on different clocks. Read together, they show a house becoming a bundle of systems rather than a single possession.
Homeownership% of occupied housing units owner-occupied 13 of 13 rooms charted
Complete plumbing% of homes with complete plumbing 7 of 13 rooms charted
Air conditioning% of households with AC 6 of 13 rooms charted
Vehicle at home% of households with a vehicle 7 of 13 rooms charted
Median home sizemedian sq ft, new single-family houses completed 6 of 13 rooms charted
Median gross rentUSD/month, nominal (specified renter-occupied units) 7 of 13 rooms charted

Signals into the home
How did the outside world cross the walls?
Broadcast, voice, cable, computing, and networks arrived in waves. Short series remain short: an absent line is not filled from a later technology with a similar name.
Radio% of households 1 of 13 rooms charted
Television% of households 3 of 13 rooms charted
Household landline telephone% of households 5 of 13 rooms charted
Cable television% of households with TV 3 of 13 rooms charted
Home computer% of households 1 of 13 rooms charted
Internet at home% of households 1 of 13 rooms charted

The household economy
Where did the family's time and money go?
Paid hours, unpaid production, prices, and the food budget expose the work behind the room. This wing also holds the computed affordability exhibits: ratios made at build time, never authored as facts.
A median home · in hours of workPrice ÷ the room's wage anchor · computed at build 9 of 13 rooms charted
Tier letters carry the weakest input. The ratio is computed, never authored as a fact.
A new car · in hours of workPrice ÷ the room's wage anchor · computed at build 13 of 13 rooms charted
Tier letters carry the weakest input. The ratio is computed, never authored as a fact.
Budget compositionShare of household expenditure · fixed categories 7 rooms charted

Weekly hours, manufacturinghours per week, production workers 3 of 13 rooms charted
Expenditure-to-income ratio% (total expenditures ÷ income before taxes, all CUs) 5 of 13 rooms charted

The study table
Put two decades on the same table
The atlas follows one measure through time. Pairwise pages instead gather every fact family the measure guard certifies comparable between two chosen rooms.

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.
