The EU economy largely depends on a few countries, particularly its ‘Big Four’. As of 2025, Germany, France, Italy and Spain together account for 61% of the EU’s GDP.
However, countries’ shares of the EU economy change over time. The share held by the ‘Big Four’ has been declining in recent decades. It fell from 67.9% in 2005 to 65.3% in 2015 and 61% in 2025, according to Eurostat.
