FAO Global and Regional Food Consumer Price Indices (CPI) measure food inflation for a group of countries at different geographical scales: regional (e.g. South America), continent (e.g. Americas) and global (world, all countries). The Global Food CPI covers approximately 120 countries worldwide, representing more than 90% of the world population.
The source of data for the CPIs is the International Labour Organization (ILO) and 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.
