FAO’s Global and Regional Food Consumer Price Indices (CPI) measure food inflation for a group of countries at different geographical scales: sub-regional (e.g. South America), regional (e.g. Americas) and global (world, all countries). The Global Food CPI covers approximately 150 countries worldwide, representing more than 90% of the world population.
The source of data for the country CPIs are the International Labour Organization (ILO), the UN Statistics Division and websites of national statistical offices or central banks. The aggregation procedure is based on the use of population weights. We gratefully acknowledge the Statistics Division of the ILO for their methodological and technical guidance on the compilation of regional food inflation indices.
Because of significant conceptual and methodological differences involved in the compilation of national CPIs by countries around the world, any global and regional CPI aggregates should be used with caution.
A more detailed description of the indices is provided in the note: Regional Aggregations of Food Consumer Price Indices, Statistics Division, FAO, August 2013.
