Consumer prices

The Consumer Price Index measures the change in prices over time of a set of goods and
services (CPI basket) representative of Italian household consumption.

In September 2011:

• the National Consumer Price Index for the whole nation CPI (see Italian NIC) – used to
measure inflation over the entire Italian economic system – held steady compared to the
previous month and rose by 3.0% in comparison to the same month of the previous year;

• the EU Harmonized Index of Consumer Prices HICP (see Italian IPCA) – developed to
facilitate the comparison of inflation between Member States – rose by 2.0% compared to
the previous month and by 3.6% in comparison to the same month of the previous year.
