Abstract: This paper introduces a global database that contains inflation series: (i) for a wide range of inflation 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 period (1970–2023); and (iii) for a large number (up to 209) of countries. As it doubles the number of observations over the next-largest publicly available sources, the database constitutes a comprehensive, single source for inflation series. It also illustrates the potential use of the database with three applications. First, it studies the evolution of inflation since 1970 and documents the broad-based disinflation around the world over the past half-century, with global consumer price inflation down from a peak of 16.9 percent in 1974 to 2.5 percent in 2020, before rising to 7.8 percent in 2022. Second, the paper analyzes the role of common factors in explaining movements in different measures of inflation. While, across all inflation measures, inflation synchronization has risen since the early 2000s, it has been much higher for inflation measures that involve a larger share of tradable goods. In addition, the paper examines the behavior of inflation during global recessions. Global inflation fell sharply (on average by 0.9 percentage points) in the year to the trough of global recessions and continued to decline even as recoveries got underway.
