The report presents results from the 2017 International Comparison Program, using purchasing power parities to compare the size of world economies. It reviews major findings on economy size, GDP expenditure components, and per-capita measures, then examines intercountry income inequality and price levels. It also describes variability across economies and contrasts 2017 results with revised 2011 results. Subsequent sections outline ICP 2017 survey framework and provide tables and methods supporting purchasing power parity-based real expenditures.
