Long term economic trend

Brief Overview:

Long term economic trend represents the economic performance of nations measured on Population, GDP measured in PPP (Current international dollar) and per capita GDP measured in PPP (Current international dollar). The data-set covers 1500 A.D. and 2016. For the period 1980-2016, the source of data are World Economic Outlook Database from IMF. For the period 1500 A.D. to 1979, our data-set are based on New Maddison Project database published by Maddison project scholars. 

We are thankful to Angus Maddison and his group of colleagues that initiated Maddison Project in March 2010. Angus Maddison was a world scholar on quantitative macroeconomic history, including the measurement and analysis of economic growth and development. Inter-country comparison on economic performance relies on purchasing power parity converter (PPPs) developed by Kravis, Heston and Summers.

The GDP has been represented in units of current international dollar which is equivalent to the PPP exchange rate using 2011 as the reference year. For information on detailed methodology of PPP exchange rate computation please click here.
