The Global Trade Analysis Project (GTAP) Data Base: Version 11

This paper describes the construction of the Global Trade Analysis Project (GTAP) Data Base, version 11. The Data Base reconciles different data sources at a global scale for analytical use and provides time series data on value flows, volumes, and various tax instruments. GTAP 11 offers a time series of 5 reference years (2004, 2007, 2011, 2014, and 2017), distinguishes 65 sectors in each of 141 countries and 19 aggregate regions—with extensive individual countries accounting for 99.1% of world Gross Domestic Product (GDP) and 96.4% of world population. The exhaustive nature of GTAP’s economic activity coverage facilitates its use in economy-wide studies of global economic issues.
