National numbers vs. totals of states
Could you comment on the extent to which variables in the state models should total to the values in the national model and why they might not? I totaled household demand in the Industry Accounts (a fairly arbitrary choice as a test) across the 50 states and DC (2010 model) for the "Total" industry and get $7.84 trillion compared to $9.82 trillion in the national model. The smaller industries are also off (e.g. $273 million vs. $333 million for oilseed farming). What am I missing?

Perhaps related: when I aggregate the US model at the 3-digit NAICS level, the total household demand increases from $9.82 trillion to $9.95 trillion. Can you explain why this is?0

IMPLAN SupportHi Erica. Based on your Forum Post, please make sure that your comparison is made using the Study Area reports. Social Accounts and Industry Accounts will have domestic imports removed from the demand and not add up to the National model. Please let us know if we can be of further help.0 -
Thanks, this works out exactly. Could you comment on the difference between (the now reconciled) US household demand in the 2010 IMPLAN ($10.461 trillion) and 2010 BEA Personal Conumption Expenditures ($10.202 trillion)?0

IMPLAN SupportHi Dan. The numbers differ for two primary reasons: 1. You are looking at a revised table. That is, the BEA updates their numbers periodically after initial release. The original value we got from NIPA Table 2.5.5 was $10.2455 trillion. 2. In IMPLAN, negative final demands (i.e., Scrap and ROW adjustment) are removed from final demands and put into institutional make of commodities - i.e., they become positive institutional sales). Taking away these negatives results in the $10.461 trillion figure you see. Please let us know if we can be of further help.0
