Approaches to measuring inflation in developed countries and methodological implications for Uzbekistan

This article analyzes the main approaches to measuring inflation in developed countries and develops methodological implications for Uzbekistan. Based on the experience of the United States, the European Union, the United Kingdom, Japan, and Australia, the study examines systems of consumer price indices, core inflation indicators, weighting and aggregation methods, as well as emerging trends in the use of digital data sources. The results show that in developed economies, inflation measurement is not limited to a single aggregate index; rather, it is based on a comprehensive system of indicators designed for different purposes, supported by modern data sources and continuous methodological updates.
