Doug, Please ignore my previous question, because I found the 2008 data looks fine when I use the IMPLAN version3. However, I still have questions regarding data in general. 1. What is the difference between gross regional product and the total regional output? In my case, the GRP is 137 billion, but the total regional output is $300 billion. 2. The Shannon-Weaver index should not change, because it represents the diversity of the industry in that region. However, it changes everytime if I change the model from 2 digit NIACS to 3 digit NAICS. Can you tell me why? Thank you! Mike Jin CLCR
