  1. All the percentage differences are exactly zero for year 2000 since it is the base year for the constant price IO tables. | Δ % | n = 130 is the absolute value of the percentage difference when the number of sectors is n = 130. The exogenous final demand vector is the average of 2001-2007 final demand vectors in current prices, while the outcomes are gross outputs in constant prices whose overall percentage differences for methods A, B and C are reported.
