Understanding the dynamics of inflation requires a comprehensive database that covers a large number of countries over a long period. This column introduces a new global database of inflation that has a significantly larger coverage than other databases as it includes multiple measures of inflation for up to 196 countries over 1970-2021. The database can be used in a variety of contexts. A few potential applications are illustrated, analysing the evolution of inflation since 1970, the behaviour of inflation during global recessions, and the synchronisation of inflation across countries and over time.
