What the data teaches

The atlas lets you look anything up. These pieces do the opposite: they start from the full matrix — 26 measures × 23,818 ZIP/ZCTA areas — and show the structure that emerges. Everything is precomputed from the same public payloads the atlas serves; every figure is interactive.

The structure of place-based health

Most of ZIP-code health is one axis

57% of variance, one axis

Run a principal component analysis on all 26 measures and a single dimension — tracking deprivation and income, not any one disease — explains the majority of the variation between America's ZIP codes.

Correlation structure

No measure moves alone

ρ 0.98 food insecurity × transport barriers

Diabetes predicts blood pressure. Food insecurity predicts housing insecurity at ρ ≈ 0.97. The 26 measures form tight blocks — and the blocks track demographics more than medicine.

Community archetypes

The four health Americas

4 archetypes, 32k ZIP areas

Cluster ZIP codes on all 26 measures at once and four recognizable kinds of community emerge — comfortable suburbs, young metro strivers, aging small towns, and left-behind communities.

The deprivation gradient

Where the gradient bites — and where it doesn't

3.1× teeth lost, most- vs least-deprived

Complete tooth loss is three times higher in the most-deprived tenth of neighborhoods. Binge drinking is the one measure that runs the other way.

The wealth gradient

The health premium of wealthy ZIP codes

23/26 measures worse in bottom wealth decile

Rank ZIP/ZCTA areas by a composite of income, college attainment, home value, ADI, poverty, and unemployment, then compare the richest tenth with the poorest tenth across all 26 health measures.

Outcome story · mental health

Distress follows poverty. Diagnosis follows privilege.

ρ -0.35 diagnosis ratio × Black population share

Frequent mental distress tracks deprivation closely; diagnosed depression barely does. The gap between the two — diagnoses per unit of distress — rises with income and falls sharply where more residents are Black.

Outcome story · smoking

Smoking: deprivation predicts it, culture bends it

ρ 0.8 smoking × neighborhood deprivation

No measure tracks neighborhood deprivation more tightly than smoking (ρ = 0.80). Subtract that prediction and what remains is a map of history: the tobacco belt, Utah, and the casino frontier.
