2007 IMPLAN State Data What does IMPLAN/MIG do to update this data every year? BEA does its benchmark I-O surveys every 5 years (on the 2s and 7s) with updates annually using smaller scale surveys. Currently we have 2003 data, which is really from the 1997 I-O survey, right? However, IMPLAN/MIG puts out new data every year. Does it include just the BEA updates, or do you do more to it than that?
