Definitions
  • « Foreign national » = person with a non-Belgian nationality in the national register, on 1 January. Naturalised Belgians or Belgians of foreign origin are counted as Belgians.
  • Origin (Statbel): based on current nationality, the person's first registered nationality and that of their parents. Official categories: Belgian of Belgian origin, Belgian of foreign origin, non-Belgian.
  • Group of nationality of origin: Statbel grouping into neighbouring countries, EU27 excluding neighbouring countries, and non-EU27; this is not a strict EU / non-EU split (the United Kingdom is classed as a neighbouring country).
  • Merged or renumbered municipalities: no reconstructed series before the date of the new code (same rule as for the reference population).
  • These figures are not cross-referenced with any crime statistics.

Change 2025/2024: change in 2025 compared with 2024 (e.g. −10 % = 2025 is 10 % lower than 2024, not the reverse).

2025 provisional: first publication. Reports registered late are added in later bulletins, which revise the figures upwards, so the 2025/2024 fall may be overstated.
