US WARN Act Layoff & Closure Notices — normalized snapshot (2026-07-29)

5,660 US WARN Act layoff and closure notices, normalized to one schema across 5 states: TX (2,358), CA (1,632), IL (1,369), NC (236), NY (65). Covering 528,129 affected workers and 4,635 distinct employers, with effective dates from 2010-10-30 to 2028-02-01.

This is a frozen snapshot

Taken 2026-07-29. It does not update. WARN filings arrive continuously, so this file begins going stale the day it is published — that is intentional and it is stated plainly rather than buried.

Why this exists

WARN Act notices are public records, published by individual state labor agencies. They are also published in five mutually incompatible ways: two spreadsheet dialects, born-digital PDFs with differing table geometry, and portals that disagree about what a date is. The work in this dataset is not access, it is normalization — one schema, typed fields, ISO dates, and a stable provenance key per source artifact.

Schema

Column	Type	Notes
state	string	USPS two-letter code
company_name	string	Employer as filed
employees_impacted	integer	Headcount from the notice; null when the filing omits it
effective_date	string	ISO date the layoff or closure takes effect
notice_date	string	ISO date the notice was filed — the lead-time signal
location	string	County-level location as filed
layoff_type	string	e.g. Closure Permanent, Layoff Temporary
raw_source_file	string	Stable provenance key for the source artifact
parsed_timestamp	string	When this row entered the corpus

Nulls are honest. Where a filing genuinely does not state a value, the field is null rather than zero or a guess — a stored NULL beats confident garbage.

Contents

• warn_notices.csv — 5,660 rows, header included
• warn_notices.jsonl — the same rows, one JSON object per line
• coverage.json — counts by state, date range, totals

Known data quality notes

• 55 rows have no effective_date. The underlying filing did not state one. Stored null rather than guessed.
• 2 rows carry an effective_date before the WARN Act existed (1930-03-30, 1930-03-31). These are parsing artifacts, not history — their notice_date values sit in the correct era. They are retained rather than silently dropped, and excluded from the headline date range above.
• Company names are as-filed and not entity-resolved. One employer may appear under several spellings.

Provenance and limitations

Derived from public state WARN Act filings. Coverage is the five states above; states absent here are absent because of acquisition barriers (WAF blocks, JS-rendered portals, unstable PDF geometry), not because their data is unimportant. No personal data is included; these are corporate filings.
