National CSV columns

ColumnMeaning
fips5-digit county FIPS code (stable identifier).
county, state_uspsCounty name and 2-letter state.
national_caeriCAERI composite score (0–100), national basis.
national_percentile, national_rankStanding among all scored U.S. counties.
national_tierRelative-standing band by national percentile: Top 10% / 75th–90th / 50th–75th / 25th–50th / Bottom 25%. A ranked position among all U.S. counties, not a condition assessment.
national_confidenceHigh / Medium / Low — trust in the estimate (source agreement, disclosure imputation, county size). Distinct from the tier band above.
p1p5Pillar national percentiles: P1 direct occupational exposure, P2 economic concentration, P3 adaptive capacity (inverted), P4 regional buffer (inverted), P5 fiscal sensitivity.
instate_caeri, instate_percentile, instate_rank, instate_confidenceThe same score, percentile, rank, and confidence computed within the county's own state. There is no in-state tier band (removed v0.3.1): percentile bands are incoherent in small states (DC has 1 county, DE 3). Use the rank — it is strictly more informative.

Two comparison bases

Every county carries both a national standing (vs. all U.S. counties) and an in-state standing (vs. its own state's counties). They can differ sharply; both are shown so a reader can pick the comparison that fits. Only the national basis carries a tier band; the in-state basis is reported as rank and percentile.

Tiers & pillars

Tier bands are relative-standing cuts on the national percentile, not condition assessments: Top 10% (90th percentile and above), 75th–90th, 50th–75th, 25th–50th, and Bottom 25%. They apply to the national basis only. P3 and P4 are resilience pillars (higher = more resilient) and are inverted inside the composite. Pillar weights and the full construction are in the methodology.

Per-county JSON

Each county page links a JSON file with a metadata block (identifier, canonical URL, methodology version, sources, license), a scores block (national and in-state bases + pillar percentiles), and any data_quality_flags.
