    Hello, this is a very good observation on your part and worthy of a question! The value is correct and is reflected in the latest (2007) BEA Benchmark data. The annual data we collect for OPI and TOPI also come from the BEA but they are at a very aggregate sector level (there is only one overall “Farm” sector) so we have to distribute this annual figure to the 14 IMPLAN farm sectors based on ratios from the BEA Benchmark (which happens to have negative TOPI for Grain Farming). Please let us know if you have additional questions.
