The Conference Board Total Economy Database™, (TED) is a comprehensive database with annual data covering GDP, population, employment, hours, labor quality, capital services, labor productivity, and total factor productivity for about 123 countries in the world.TED was developed by the Groningen Growth and Development Centre (University of Groningen, The Netherlands) in the early 1990s, and starting in the late 1990s, it was produced in partnership with The Conference Board. As of 2007, the database was transferred from the University of Groningen to The Conference Board, which has maintained and extended the database since then. In January 2010, the database was extended with a module on sources of growth, including labor quantity and quality, capital services (non-ICT and ICT), and total factor productivity. The extended module aims to integrate two previous data sets: the world economy productivity data set created by Dale Jorgenson and Khuong Vu of Harvard University and the Total Economy Growth Accounting Database of the Groningen Growth and Development Centre.
