Distribution of item-level movements

The table below outlines the distribution of price movements in August and September 2008. The Food Price Index (FPI) has been partitioned into those national item-level indexes that increased, showed no change, or decreased.

The distribution of item-level movements shows that:

  • the percentage expenditure weight of items that increased in price fell, while the percentage expenditure weight of items that decreased in price rose
  • the weighted average price increase fell, while the weighted average price decrease rose
  • the percentage of expenditure weight of items that increased in price is significantly greater than the percentage of expenditure weight of items that decreased in price
  • the weighted average price decrease is now greater than the weighted average price increase.

These movements resulted in a 0.6 percent increase in the September 2008 FPI, compared with a 2.7 percent increase in August 2008.
