In the 1997, as well as the prior year Benchmark tables, government purchases are shown as part of final demand, as either government consumption expenditure or as government investment. Input coefficients do not represent final demand, so there are no input coefficients for government. If you need the data on purchases of government, use the final uses categories of the interactive I-O table when choosing industries. It is important to note that government purchases are shown as intermediate inputs in the 2003 NIPA revision and the successive updated Annual I-O tables. Government purchases will also show up as intermediate inputs in the 2002 Benchmark I-O table.
