The Three Seas Initiative covers 32% of EU territory.

Omissions

• The claim uses slightly higher figures than those documented in available sources. The Polish Institute of Economics (PIE) reports 29% of EU territory post-Brexit, not 32%. Population figures from multiple sources indicate approximately 25% of EU population, not 27%. GDP share is documented at 10.8% to 14.4% across different studies, below the claimed 16%. The territorial data may vary depending on whether land cover or total area is measured, and whether overseas territories are included in EU calculations.
• Source publication dates vary, with some data reflecting post-Brexit EU-27 rather than current EU composition.
