Global Inflation Database

Ayhan Kose and friends at the World Bank have a long history of producing useful products. This seems to be no exception. From his email:

We’ve released a new study, “One-Stop Source: A Global Database of Inflation,” that introduces a database with inflation series: (i) for a wide range of measures (headline, food, energy, and core consumer price inflation; producer price inflation; and gross domestic product deflator changes); (ii) at multiple frequencies (monthly, quarterly and annual) for an extended time period (1970-2021); and (iii) for a large number of (up to 196) countries. As it doubles the number of observations over the next-largest publicly available sources, the database constitutes a comprehensive, one-stop source for inflation. You can download the study and the database here: https://www.worldbank.org/en/research/brief/inflation-database.
