Belgium’s population is about 11.8 million people. Recent estimates put it at roughly 11,77 million in 2026, depending on the source and whether the estimate is midyear or current-population based.

Quick Scoop

  • Latest estimate: about 11.77 million.
  • Other recent estimate: about 11.96 million for a 2025 estimate in a different source methodology.
  • Population figures can differ a bit because some sources use midyear estimates and others use live/current estimates.

Why the numbers vary

Different databases count population in slightly different ways, so a country can have multiple “correct” figures depending on the method. For a simple headline answer, 11.8 million is the safest rounded figure.
