GDPIndex
In-depth GDP, growth, and history for every G20 economy. Sourced from World Bank, IMF, FRED, BIS, ECB.
What is GDP — and how is it calculated?
Gross Domestic Product is the total value of everything a country produces in a year. Economists add up four kinds of spending. Together they equal GDP.
Households buying groceries, rent, cars, Netflix. The biggest piece almost everywhere — usually 55-70% of GDP.
Companies building factories, buying machines, writing software. New housing counts too. 15-25% of GDP.
Roads, schools, salaries of public workers, defence. Transfer payments like pensions are not counted here. 15-25% of GDP.
What a country sells abroad minus what it buys. Positive for exporters like Germany, negative for the United States and the United Kingdom.
Numbers on this site are nominal GDP in current US dollars, reported by the World Bank and IMF. See the methodology for sources, currency conversion, and how PPP differs.
This site analyses the twenty largest economies in the world — the G20 — through the single lens that determines living standards: economic output. Each country page combines four decades of data with an editorial story about why the numbers look the way they do.
