The Census counts 20 establishments in Mercer County across the classes this site tracks.
This is a small published count: with fewer than 30 establishments, county figures say little about local supply, so lean on the Pennsylvania capacity figures and treat the numbers here as context only.
Pennsylvania overall: 1,621 establishments across the five classes, of which machine shops are the largest. Mercer County sits below the state's typical county for these classes.
