Global EPU Index with monthly PPP GDP 1997-2024

*The global EPU Index is measured based on purchasing power parity-adjusted GDP. PPP-adjusted GDP controls for different costs of living and price levels (usually relative to the U.S. dollar), enabling a more accurate depiction of a given nation's level of production.

The index value is constructed by normalizing each national EPU index to a mean of 100 from 1997 (or first year) to 2015, then computing the GEPU Index value for each month as the GDP-weighted average of the 21 national EPU index values. Each national EPU index reflects the relative frequency of own-country newspaper articles that contain a trio of terms pertaining to the economy (E), policy (P) and uncertainty (U). The countries included are: Australia, Brazil, Canada, Chile, China, Colombia, France, Germany, Greece, India, Ireland, Italy, Japan, Mexico, the Netherlands, Russia, South Korea, Spain, Sweden, the United Kingdom, and the United States.
