Methodology
Source: U.S. Census Bureau, County Business Patterns 2022, NAICS 334413 (Semiconductor and related device manufacturing)
Measure Semiconductor Plants, ranked highest first across all U.S. states
(36 ranked in total).
How the headline figure is computed The top three units' combined count divided by the combined count of all 36 ranked units.
Universe Places below a 5,000-resident floor are excluded so a median computed on a handful of households cannot top the ranking.
