Consumer Price Indices (CPIs) are economic indicators constructed to measure the changes over time in the prices of consumer goods and services acquired, used or paid for by households.
Harmonized Indices of Consumer Prices (HICPs) are designed for international comparisons of consumer price inflation.
HICPs are compiled on the basis of a legislated methodology, binding for all Member States (MSs). The focus is on quality and comparability among the indices of different countries as well as on their relative movements.
The HICPs aim at measuring "pure" price changes using a harmonized methodology. In order to achieve this, a number of regulations set the technical frame. They cover among other things minimum standards for quality adjustment, sampling, coverage and basic aggregation formula. The HICPs are Laspeyres-type indices.
The HICPs are in principle open to revision, in particular when new or improved information becomes available. Monthly releases may include provisional data that is confirmed the following month.
