The Maddison Project, also known as the Maddison Historical Statistics Project, is a project to collate historical economic statistics, such as GDP, GDP per capita, and labor productivity.[1][2][3] It was launched in March 2010 to continue the work of the late economic historian Angus Maddison. The project is under the Groningen Growth and Development Centre at the University of Groningen,[2] which also hosts the Penn World Table, another economic statistics project.[4]
