This question is not regarding IMPLAN per-se, but could be relevant to modifying local models. I'm in search of someone with experience working with building regional I/O models from national I/O matrices. I'm working with Mexico's national I/O table at the 4-digit NAICS code level, regionalizing it to the state level using the CILQ method. The industries I'm interested in are agriculture and fisheries, and the national matrix doesn't provide ag industries by 4-digit NAICS code. Fisheries and ag need to be separate because I'll be comparing impacts in the two sectors. I have some rough estimates of value of production for ag, but I would be using this to fill in the gaps for state GDP data on ag (which is not available) in order to build my location quotients. Are there any resources available on the best methodologies for filling in data gaps for regionalizing I/O matrices? Thanks for any suggestions you can provide
