PA Industry Clusters
An industry cluster consists of a group of industries that are closely linked by common product markets, labor pools, similar technologies, supplier chains, and/or other economic ties. Clusters can take on strategic importance because activities that benefit one group member will generally have positive spillover effects on other members of the cluster.
 
Twelve industry clusters, with critical sub-clusters, have been identified for workforce strategies. These twelve clusters account for nearly 82 percent of all employment in the commonwealth.
