statisticalsector open data

Statistical Sectors (Statistische sectoren / Secteurs statistiques) of Belgium, 2025. Finest statistical unit, the smallest join level. niscode = 9-char sector code ('11001A00-') = 5-digit municipality NIS + sub-sector suffix, so it rolls up to municipality. Code-only (no names — join on code). The six sectors the publisher ships as separate single-polygon rows per part (Baarle-Hertog's enclaves, a Saint-Gilles avenue sector and La Marlette) are dissolved on niscode, so niscode is a unique key over all 20,781 sectors.

Statistical sectors of Belgium as at 1 January 2021 — Statbel's 'Statistical sectors 2021' product, the vintage the 2021 Census (Census 2021 / STATBEL S-tables) is published against. 19,795 sectors. CS01012021 is the 9-character sector code and the join key; CNIS5_2021 is the 5-digit municipality NIS code, which rolls these up to the 581 municipalities of that vintage. Names in Dutch, French and German (T_SEC_NL / T_SEC_FR / T_SEC_DE) — 43 sectors carry no name in any of the three languages, code only. 286 sectors carry no census row in any table: zero-population port, industrial and water sectors, boundary-only by design. Geometry generalised at 0.0001 degrees. This is a VINTAGE-PINNED companion to the current 2025 statistical sectors, not a replacement for them — the 2025 REDEGEO reform split 814 sectors and recoded the merged municipalities, so 2021 census codes do not join the 2025 boundary.
