Results change when the region changes

    If the industries in the surrounding counties have different relationships (i.e., Output per worker, Labor Income per worker, etc.) your reults will change when you include these surrounding counties because you are now impacting the "average" industry for the 7 counties rather than the industry specific to the first county. This is why we developed the multi-regional Input-Output (MRIO) capability of IMPLAN - it allows you to specify where the impact occurs while still seeing the effect that has on other regions. If the direct impact occurs solely in the first county but you want to see what effects this will have on the surrounding counties, we recommend using MRIO. Here are a few Knowledge Base articles to get you started: Please let us know if you have additional questions.
