Consumer price indices (CPIs) measure changes over time in the level of prices of goods and services that households consume. In many countries, they were originally introduced to provide a measure of the changes in the living costs faced by workers, so that wage increases could be related to the changing levels of prices. However, over the years, CPIs have widened their scope. Nowadays, they are widely used as a macroeconomic indicator of inflation, a key statistic for governments and central banks for inflation targeting and for monitoring price stability. They are also used as deflators in national accounts. With the globalisation of trade and production and the liberalisation of markets, national governments, central banks and international organisations place great importance on the quality and accuracy of national CPIs, and in their international comparability.
The manual provides an overview of the methods and practices national statistical offices should consider when making decisions on how to deal with the various problems in the compilation of a consumer price index (CPI). It is an update of the 2004 CPI manual.
The COVID-19 crisis is affecting data collection activities of national statistical offices (NSOs) around the world, including for consumer price indexes (CPI).
This comprehensive manual provides guidelines for statistical offices and other agencies responsible for constructing CPIs and explains in-depth the methods that are used to calculate a CPI. It also examines the underlying economic and statistical concepts and principles needed for making choices in efficient and cost effective ways and for appreciating the full implications of those choices.
This handbook provides comprehensive guidelines for the compilation of RPPIs and explains in depth the methods and best practices used to calculate an RPPI. It also examines the underlying economic and statistical concepts and principles guiding the methodological choices on which the indices are based. The handbook primarily addresses official statisticians in charge of producing RPPIs, and provides a harmonized methodological and practical framework for all parties interested in their compilation. Written by leading academics in index number theory and by recognized experts in RPPIs compilation, this handbook was co-ordinated by Eurostat, with the collaboration of the ILO, the IMF, OECD, UNECE and the World Bank.
