FactoryRegistry lists 32,316 facilities whose primary industry classification is one of the 18 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced Developing and making prototypes of other goods (excluding aircraft, aircraft engines and parts, guided missiles, space vehicles, space vehicle engines, propulsion units, and missile and space vehicle parts and components), 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.
