US county business vitality (annual, by NAICS sector)

Annual US county business-vitality intelligence from the keyless U.S. Census County Business Patterns bulk files (2021-2023): one row per year per county (~3,190 counties) per NAICS 2-digit sector (20 sectors) plus an all-sectors county row. Each row carries establishments, March-12 paid employment, Q1 and annual payroll (normalized to whole dollars), average pay per employee, the small-establishment (<5 employees) share, and the Census noise-infusion flag. Derived: exact year-over-year changes in establishments/employment/payroll (null when the prior year is absent, never interpolated), 2021->2023 two-year CAGRs, each sector's share of county employment, the county employment concentration HHI (0-10000, lower = more diversified), and a documented 0-100 county vitality score (40% winsorized employment momentum + 30% winsorized establishment momentum + 30% sector-mix diversity, min-max over scored county-years) with per-state ranks and quartile tiers, plus per-(state, sector) employment-growth ranks. Method: parse the 21-row sector panel from each CBP county file, resolve FIPS to canonical county names via the Census gazetteer, null suppressed size-class cells (never zero-fill), keep payroll in dollars. Caveats: cells carry Census noise infusion (flagged); payroll is in dollars converted from the published $1,000s; scores are relative history gauges, not forecasts; reference year lags ~2 years.
