Data source(s) used: Consumer price index for blue and white-collar worker households: It refers to consumption of households whose reference person is an employee. It is used to updated periodically monetary values. Other data characteristics: In regard to provincial data, in some months and for some provincial capitals, the index can be not calculated due to the interruption of survey operations or the non abidance of the rules and the quality standards established by IstatSuch situation are marked with flag g

Data source(s) used: Harmonized index of consumer prices: Calculated according to the EU regulations in force, it is used for the comparison of inflation between European Member States.

Data source(s) used: Harmonized index of consumer prices at constant tax rates: The HICP-CT provides a measure of the teorical impact of changes of indirect taxes (e.g. VAT and excise duties) on the overall HICP inflation. It follows the same computation principles as the HICP.

Data source(s) used: Harmonized index of consumer prices: Calculated according to the EU regulations in force, it is used for the comparison of inflation between European Member States.Consumer price index by population subgroups: The Consumer price indices by population subgroups are 'satellite' of the index of consumer prices (HICP): they are calculated using the same information base used for the HICP, the same basket and the same set of elementary indices of price, changing the structure of the weights used for their synthesis. The Consumer price indices by population subgroups have been calculated from January 2005, with reference base 2005=100 consistently with IPCA. In addition to the general index, are elaborated indexes of special aggregates. The dissemination of these indicators further expands the statistical information on the temporal dynamic of consumer prices, allowing an assessment of differential effects of inflation on specific subgroups identified on the basis of the level of total expenditure. Other data characteristics: The consumer price indices by population subgroups are “satellite” indices of the Harmonized index of consumer price (HICP): they are computed starting from the same basic information used for the HICP (i.e. the same basket of products and the same price elementary data) by modifying the system of weights used for their calculation.On 24 September 2012, HICP weight data set has been replaced cause, in the previous one, data were rounded using rounding rules not in keeping with those adopted for consumer price indices dissemination
