World Bank International Comparison Program

In May 2024, results from the ICP 2021 cycle results were released and include data for the reference year 2021.

The International Comparison Program (ICP) showed that, in 2021, the EU's gross domestic product (GDP) represented 15.2% of world GDP when expressed in purchasing power standards (PPS).

The largest economy in the world in 2021 was China with about 18.9% of world GDP. The United States was the second largest, with 15.5% of world GDP. The EU was in third place, with 15.2%.

Among the 20 countries in the world with a share larger than 1% of the world GDP expressed in PPS, there were 5 EU countries: Germany (3.4%), France (2.4%), Italy (1.9%), Spain (1.4%) and Poland (1.0%). They collectively contributed about 10.1% to world GDP.

Looking at GDP per capita for the world's 20 largest economies in 2021, only 6 countries were above the EU average: the United States, Germany, Australia, Canada, France and the United Kingdom. While the Chinese economy was the largest in terms of GDP in PPS, GDP per capita was only 39% of the EU average.

There was a nine-fold difference between the highest and the lowest GDP per capita among the world’s 20 largest economies (the United States at 137% of the EU average compared with India at 15% of the EU average).
