One of the ways to count World GDP is to add up its consumer spending, business investment, government spending, and net exports.
In 2022 World GDP was 101.326 T USD, and the previous year it amounted to 97.53 T USD.
World GDP accounts for 100% of the world GDP.
Since GDP measures an economy's output, it is subject to inflationary pressure. So real GDP is a measure of an economy's output adjusted for inflation.
The highest figure World GDP has ever reached is 101.326 T USD.
The lowest ever value World GDP has reached is 1.385 T USD.
