"This title is available in Spanish only" A technical assistance (TA) mission was conducted remotely during February 4-18, 2022, to providing guidance to the National Institute of Statistics and Geography (INEGI) of Mexico in implementing the chain-linked volume measures with previous year weights in their national accounts (NA) statistics. Currently, INEGI compiles Gross Domestic Product (GDP) and related NA economic indicators at constant prices with fixed base year indices of 2013. Chain-linked volume measures provide improved and more accurate estimates of economic growth, especially in periods of structural change. The TA mission also provided extensive training on compiling chained indices with own country examples from the economic surveys and national accounts statistics to a large group of INEGI staff and discussed with INEGI management an action plan for developing and implementing chained indices for the national accounts and short-term indicators.
