State Competitiveness Report 2001
Defining “competitiveness” as the ability to ensure and sustain a high level of per capita income and its continued growth, the authors combined more than three dozen variables into nine sub indexes, each of which represents an element of competitiveness. The authors then combined the nine sub indexes into an “overall index” and ranked the states according to their overall competitiveness in order to examine all aspects of a states economy.
