The EU's share of global GDP has consistently declined over the last 20 years, as the economies of other nations, particularly China, have grown at a faster rate. Around 2002, the EU's share of global GDP (in PPP terms) was nearly 20%, falling to approximately 14.33% by 2024.
While I cannot generate an interactive graph, the general trend is a steady downward slope. Visualizations from sources like the International Monetary Fund (IMF) and Statista illustrate this shift, often comparing the EU's share with the stable US share and the significantly increasing Chinese share.
