It is time for a change. Faithful readers of this space will recall that the Evansville economy did not show substantial growth after the turn of the century, according to the index of economic activity maintained at the University of Evansville. That index used fixed 1998 value-added components from that year’s gross domestic product (GDP) as its fixed weights. This fixed weight index methodology is similar to the way the Consumer Price Index is calculated. This year, the weights have been updated and the hospital sector has been added.
