I'm working on an analysis related to the mining industry in Northeast Minnesota. In describing the study area, I included a graph that showed value added by industry for the eight sectors in IMPLAN's default aggregate scheme. The mining industry was reported to have contributed $1.1 billion to the region's total value added.
However, in another section of the report, I pulled data from the Bureau of Economic Analysis website, which showed $2.1 billion in GRP (2018, in current dollars) for the mining industry (two-digit NAICS sector 21). I can't figure out why the value shown in IMPLAN would be so different from that reported by the BEA. I tried to find a more detailed list of the IMPLAN sectors included in the default aggregation scheme, but every link I found on the forum was broken. Can you help me?
