    Hi Omkar, Thank you for your post! MRIO or (Multi Regional Input/Output) allows you to see the feedback impacts from one region to another. Instead of aggregating several regions together and losing the identity of each region, MRIO will allow those identities to be kept. In addition, MRIO captures more spending and reduces leakages. Without MRIO, we have no idea how much spending regions outside Washington County will be directed to Washington County, but we do take this into account with MRIO. This is the reason for the additional jobs in Washington County using the MRIO method. You are correct in that MRIO is only for impact analysis only and not contribution. For a contribution analysis, you are not wanting to add on any impacts from outside the region; rather, you are trying to look at the contribution of existing industry within the region. Thank you!
