Data source: Each employee count is derived from Veridion’s business and location-based data. Veridion aggregates information from multiple sources (company websites, news articles, public employment filings, government registries) and infers each plant’s headcount by cross-checking against related signals such as building footprint, industry type, known production capacity at the site, and supply chain disclosures.
Methodology: I ranked the top 20 plants by estimated headcount at a single physical site, not company-wide totals. Where a company operates a tightly clustered campus under a single name (e.g., Foxconn Longhua, Samsung Pyeongtaek), the contiguous facilities are treated as a single entry. Counts are rounded to the nearest thousand; all figures are estimates with a margin of uncertainty.
Tools: Python for data processing, Claude for visualization

Hmm I’m not sure how accurate this is. I’m very familiar with the mega facility from VW, and there are definitely not that many people employed there. Closer to half of that number

Fascinating data—Foxconn’s Zhengzhou plant alone employs around 300,000. Any breakdown by industry?

Noticed how there’s not one American plant on that list lol.

A quarter million people for one plant? Is that accurate? That’s basically a whole city in itself.

I ain’t seeing ‘Murica on this here list? Trump told me we’re the most productive, so productive country and new plants are popping up like weeds.
