Weight of Harmonised Consumer Price Index

The package includes the weights of a harmonised consumer price index. “Weight” means the pro-mille percentage of household monetary consumption expenditure for the purchase of goods and services belonging to a particular HICP basic population. The higher the weight, the greater the impact of price changes in a certain level of classification of goods and services on price changes in a higher level of price classification of goods and services. The main sources for the development of the weighting system are statistical surveys of national accounts and household budgets on household monetary expenditure on consumer goods and services. Other sources of statistical data shall also be used to prepare the weighting system: statistical information on domestic trade, transport, tourism, energy, social statistics, other institutions and enterprises to assess unaccounted household expenditures; statistics and information on monetary consumption of domestic households and visitors from abroad – statistics and information on industrial, domestic and foreign trade, education, transport, tourism statistics, other enterprises and institutions. HICP weights have been calculated since January 1996 and processed monthly.
