FactoryRegistry lists 2,274 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced transistors, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.

The U.S. Census Bureau recorded this product line in 1 US manufacturing industry in the 2022 Economic Census, as the most specific line that industry reported, where 66 establishments reported producing it.

These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.

NAPCS collection code 2033650000. Source for the product line, the establishment counts and the shares: U.S. Census Bureau, 2022 Economic Census (ECNNAPCSIND2022). Federal source data is public domain. Facility records are compiled separately by FactoryRegistry and carry their own sources.
