Occupation Clusters

Introduction into concept of clusters

Over the last 15 to 20 years, cluster analysis has emerged as a new way of looking at economic development, integrating regional differences in development and economic specialization (Porter 1990, 2003; Sweeney and Feser 1998; Feser 2004, Cortright 2006). An increasing number of states
and regions in the United States and overseas have modified their economic development strategies to focus and capitalize on the business and industry clusters where they have, or would like to have, a competitive advantage. In adopting a cluster strategy, states and regions hope to maximize their competitive advantage in existing industries and to build new strengths in the emerging industries that will replace older, declining sectors (Nolan 2003).

Most authors attribute at least four characteristics to clusters:

(a) a geographically bounded concentration of similar, related, or complementary businesses;

(b) active channels for transactions and communications among these businesses;

(c) shared and specialized infrastructure, labor markets, and services; and

(d) common competitive opportunities and threats

It is important to understand that economic clusters are not mutually exclusive in terms of the industrispecial'nymes that comprise them. The driver industries are the target and provide the name for the cluster, while the supporting industries may span the typical categories of economic sectors. These sectors are united in their foundational support of the driver industries.

How clusters are defined

The research team defined 17 clusters at the six-digit NAICS level. One of these clusters, the manufacturing supercluster, was subsequently disaggregated into six more- specialized subclusters. Although there is no universally defined or accepted set of clusters, the basic principles underlying the cluster concept were used to specify the 17 used in this study.
