We have noticed significant differences in impact results with the 2013 IMPLAN data for California (compared to 2012 data for the same state). Below are results of household income and housing construction impacts. We understand that the industrial classification system used by IMPLAN has been expanded and that the BEA data has been revised, but the differences are substantial. For example, the household impact with 20013 data is approximately 50% the size of the impact based on 2012 data. The housing construction impact reveals s ignificant changes in the indirect, direct, and induced impacts between 2013 and 2012. We have also compared impact results for Pueblo County (Colorado) for 2011 and 2013 data. A $1 million labor income impact is smaller in 2013, but the year differences are not as great as with the California data. The attachments contain summaries of the CA and CO impacts described above. We are long-time users of IMPLAN and are currently engaged in a project with a deadline. We would appreciate your feedback ASAP. Are there problems with the 2013 data? Should we use the 2012 data for our current project? Thank you for any assistance and guidance you can provide. [attachment=632]hfbf8ee3.xlsx[/attachment] [attachment=633]h9b7090c.docx[/attachment]
