Today, we have launched version 10.0 of the Penn World Table. This version of the database covers 183 countries and the years from 1950 to 2019. We have incorporated the latest data from the International Comparison Program, led by the World Bank, which includes the new international price comparison for 2017, revised estimates for 2011 and newly-estimated time series for the interim years. Covering a longer time span also means we incorporate revised National Accounts data for all countries based on the December 2020 data release of the United Nations Main Aggregates Database. A comprehensive discussion of changes can be found here.
