Download by-county summary (CSV, free) Every notice with county FIPS (CSV)
Because no US state workforce agency publishes one. All 48 agencies write the layoff site as free text in their own convention — "Los Angeles County", "Spring, Harris", "Chicago, 560 W. Grand Ave.", "Reynoldsburg/Franklin", "Weehawken" — and a county FIPS code is what you need to put a notice next to Census population, BLS employment, unemployment claims or election results. This page resolves that text against three public-domain Census 2020 reference files (counties, incorporated places and CDPs by county, county subdivisions). The notice archive rebuilds every morning; the county join re-runs weekly, so the newest notices are placed at the next geo rebuild.
90.8% of all notices on file get a FIPS; 96.6% of the notices that name a place at all (3,672 say only Statewide, Remote or nothing, and can never be placed). Every row carries a resolution_method column so you can keep only the methods you trust. A township name that repeats within a state is left unresolved rather than guessed; a city that straddles a county line takes the most-populous county and ships every candidate in county_fips_all.
Because a single notice in a 1,100-person town would otherwise top the table. The first version of this resolver did exactly that in the other direction: it sent 234 New York notices reading plain "Nassau" to Nassau village (Rensselaer County, population about 1,100) instead of Nassau County, and Rensselaer briefly led the per-capita ranking. It was caught by checking the raw text behind the top outlier, fixed (counties now beat places in every position), and a regression case guards it. Rates for smaller counties are still in the table and in the CSV; they are just not ranked.
Census Bureau Population Estimates Program, vintage 2023 county totals, used unmodified. They are a denominator only; we do not publish population data of our own.
Two CSVs, CC BY 4.0, no login: a one-row-per-county summary and the full notice-level file with county_fips, county_fips_all and resolution_method on every row. They are in the GitHub repository under data/ and on Hugging Face, and the resolver script ships inside the Hugging Face dataset so the method is reproducible from the public files.
Yes — credit "WARN Feed" and link this page. This build is dated 2026-09-24. States amend and re-issue notices, so a county's count can move slightly after first publication; cite the build date.
