Who is in this cut

Included: vehicle assembly plants, auto-parts and powertrain suppliers, tire and axle makers, dealerships and dealer groups, collision and body shops, car washes and vehicle-rental fleets.

What counts as automotive here: the employer name reads as automotive, auto, motors, motor company, auto parts, dealership, dealer services, auto group, collision, body shop, car wash, tire, axle, transaxle or transmission work, or is one of ~30 named makers and suppliers (General Motors, Ford Motor, Stellantis, Chrysler, Tesla, Rivian, Lucid, Nissan, Toyota, Honda, Hyundai, Subaru, Volkswagen, Mercedes-Benz, BorgWarner, Aptiv, Delphi, Visteon, Denso, Faurecia, Adient, Tenneco, Cummins, Navistar, Paccar, Harley-Davidson, Polaris) or a vehicle retailer or rental fleet (AutoNation, CarMax, Carvana, Hertz, Avis Budget, Enterprise Rent). This is the whole vehicle economy, not just assembly plants — dealerships, rental fleets and car washes are in, and you should filter them out yourself if you want factories only, which the sector_rule and location columns let you do. The word transmission also appears in some power-transmission names, so check sector_rule before quoting a count. Anything ambiguous sits in the unclassified remainder of the sector dataset.

Why this file exists

An auto plant closing is a regional economic event, and the supplier notices that follow it are filed weeks later in other states entirely. Those filings — which plant, which town, how many workers, notice date, effective date, closure or layoff — sit on 48 separate state portals and are never assembled as one automotive series. This file is that series, with the closure/layoff split the states themselves recorded.

The employers with the most automotive and auto-plant notices on record

Counted per notice, not per event: a company that files in four states files four notices. Employer names are the resolved spelling — the raw agency spelling is kept in the download.

The 15 most recent automotive and auto-plant notices

Date is the notice date where the agency publishes one, otherwise the layoff date. 276 of the 1,316 notices in this cut are recorded as a closure rather than a layoff.

How the industry is decided: no state WARN portal publishes an industry field, so there is no NAICS column to filter on. The sector here is assigned from the resolved employer name by a published rule table (19 sectors, 3,152 patterns, first match wins), and every row carries the pattern that fired in its sector_rule column so you can audit or re-cut it. The archive holds 61,428 notices; 61,232 of them carry a usable date and are in the sector file (196 have no date in either column), 32,168 come out with a sector, and 29,064 stay unclassified — and are still counted in every total shown anywhere on this site. Manual audit 2026-09-12: 4 of 60 sampled rows were assigned to the wrong sector. Rebuilt 2026-09-24.

How to check any of this

Every number on this page is computed at build time from notices_by_sector.csv (one row per notice, with the sector and the rule that assigned it), and the yearly series from sector_by_year.csv. The free HTTP API serves the whole archive as JSON, NDJSON and per-state CSV with no key. This industry is also published as its own Hugging Face dataset, and the full sector cut as one file. If a number here disagrees with the file, the file is right and it is a bug — tell us and it is fixed the next morning.
