The World Bank’s Prospects Group has constructed a global database of inflation. The database covers up to 196 countries over the period 1970-2021, and includes six measures of inflation in three frequencies (annual, quarterly, and monthly):
- Headline consumer price index (CPI) inflation
- Food CPI inflation
- Energy CPI inflation
- Core CPI inflation
- Producer price index inflation
- Gross domestic product deflator
The database also provides aggregate inflation for global, advanced-economy, and emerging market and developing economies as well as measures of global commodity prices.
The working paper, by Jongrim Ha, M. Ayhan Kose, and Franziska Ohnsorge, provides detailed information on the database and shows three potential applications of the database: the evolution of global inflation since 1970, the behavior of inflation during global recessions, and the role of common factors in explaining movements in different measures of inflation.
When using the data, please cite the following paper as the data source: Ha, Jongrim, M. Ayhan Kose, and Franziska Ohnsorge (2021). "One-Stop Source: A Global Database of Inflation." Policy Research Working Paper 9737. World Bank, Washington DC.
