How we track America's
industrial comeback.

A project is added to American Factory Tracker if it meets all three of the following tests:

1. Material scale. Announced capital investment of $100M+ or announced workforce of 200+ jobs.
2. Verifiable source. A primary public source link (company press release, SEC filing, governor's office release, or Department of Commerce notice). Aggregator coverage alone is not sufficient.
3. Physical US footprint. A factory, fabrication plant, refinery, shipyard, advanced-packaging facility, AI compute campus, or comparable industrial site located in one of the 50 US states.

• Pure corporate HQ moves with no manufacturing capacity.
• R&D or office-only facilities with no production line.
• Distribution centers and warehouses without manufacturing.
• Projects announced but later publicly cancelled (we will, however, mark scope reductions in the project record).
• Pre-2018 announcements (with rare exceptions for projects still under construction).
• Sub-threshold announcements (smaller capacity expansions, line retoolings).

"Advanced Manufacturing" is our umbrella for industrial categories that don't fit the other eight — AI compute infrastructure, data-center buildouts at AI training scale, advanced packaging, robotaxi assembly, and equipment manufacturers serving the reshoring boom.

Every US state has been systematically reviewed against the same editorial criteria. Reviewed states with qualifying projects have had those projects added to the database. A second tier of states was reviewed but yielded no projects meeting the inclusion threshold during the current tracking window (2018–present) — those are listed transparently below rather than hidden.

The post-2021 US factory boom is being driven by three federal programs — the CHIPS & Science Act, the Inflation Reduction Act, and the Bipartisan Infrastructure Law — plus state-level competition for site selection. The geography of where mega-projects actually landed is uneven and well-documented:

• Semiconductors have concentrated in Arizona, Ohio, New York, Texas, and Idaho — driven by land availability, power capacity, and CHIPS Act site-selection.
• Battery & EV plants form a "battery belt" through Georgia, North Carolina, Tennessee, Kentucky, Michigan, and Indiana.
• Steel, energy, and heavy industry concentrate in Louisiana, Arkansas, West Virginia, and Alabama — driven by energy costs, port access, and labor structure.
• States with high construction and regulatory costs (e.g., California) are underrepresented in greenfield mega-projects relative to their GDP share — though they remain important for expansions of existing footprints.

This is not a flaw in the dataset — it is the actual shape of the reshoring map. The tracker reports it as found.

Each project carries two dates: announcement_date (when the company publicly disclosed the project) and date_added (when the project was added to American Factory Tracker). The homepage "Database updated" label reflects the most recent date_added across all records, not the most recent announcement.

We do not retroactively alter announcement dates. Historical accuracy outranks the appearance of a "live" feed.

We welcome corrections from journalists, company representatives, and economic-development officials. Spot a missing project, a scope revision, a cancelled announcement, or an incorrect source link — we want to fix it. Contact channels will be published in a future release.
