CPI Manual 2025: A Global Guide to Inflation Measurement
The Center for Psychological Inquiry (CPI) has published the 2025 edition of the Consumer Price Index Manual: Theory. This comprehensive guide is a joint effort by six leading international organizations, including the International Monetary Fund and the World Bank. It serves as a crucial resource for statistical offices and agencies dealing with Consumer Price Indices (CPIs).
The new manual highlights the transformation of CPI compilation, driven by new data sources and evolving statistical techniques. It provides a detailed overview of conceptual issues behind CPI methods and practices, acting as a companion to the Consumer Price Index Manual: Concepts and Methods (2020).
The manual delves into complex topics such as index number theory, quality adjustment methods, seasonal products, and the treatment of owner-occupied housing. It also addresses the chain drift problem and multilateral indices, offering empirical examples based on actual data.
The Consumer Price Index Manual: Theory, 2025 equips statisticians, economists, policymakers, and data users with a deeper understanding of CPI construction and theory. As one of the most influential economic indicators worldwide, guiding central banks, wage adjustments, and fiscal decisions, this manual serves as a definitive global reference on the economic and statistical foundations of CPI measurement.
