Regions (Gewesten / Régions) of the Belgium, 2025. ADM1. 3 regions: Vlaams Gewest (02000), Waals Gewest (03000), Brussels Hoofdstedelijk Gewest (04000). niscode leading zero is data. Trilingual names. REPUBLISH 2026-08-26: replaces cm_X59YdM1CWjXH (dataset U6f4YSe4M2by), whose geometry was transposed (lon/lat swapped — it rendered at 4.5N 50.5E, off the Somali coast) by the boundary axis-swap defect: a 3D interchange GeoJSON is stamped EPSG:4979, whose authority axis order is (lat,lon,h), and ST_Transform honoured it. Fixed by always_xy=true in geo-ingest/crs.ts. These are the exact bytes verified on dev as i3xZNvZzVdLz — promoted, not re-produced, so prod and dev carry byte-identical geometry. Gate: bounds bracket the source exactly, lon 2.541356-6.408100 / lat 49.496956-51.505113, area 30,692 km2. key_column stamped niscode, not the namedut the previous record carried — the BE-NIS code is the declared scheme's join key.

Arrondissements (Arrondissementen / Arrondissements) of the Belgium, 2025. ADM2-sub. 43 administrative arrondissements. niscode is the 5-digit BE-NIS code (string, leading zeros are data). Trilingual names. REPUBLISH 2026-08-26: replaces cm_hdhnrBwI6sxv (dataset hAfUJi2McyCA), whose geometry was transposed (lon/lat swapped) by the boundary axis-swap defect: a 3D interchange GeoJSON is stamped EPSG:4979, whose authority axis order is (lat,lon,h), and ST_Transform honoured it. Fixed by always_xy=true in geo-ingest/crs.ts. These are the exact bytes verified on dev as cizM8Rx1V4GI — promoted, not re-produced, so prod and dev carry byte-identical geometry. Gate: bounds bracket the source exactly, 43/43 features.

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.

Municipalities (gemeenten / communes) of Belgium as at 1 January 2021 — 581 municipalities, the vintage the 2021 Census is published against, before the 2025 Flemish merger round took the current count to 565. niscode is the 5-digit NIS/INS code and the join key; names in Dutch, French and German. Built by dissolving Statbel's 'Statistical sectors 2021' layer on its CNIS5_2021 municipality code — the publisher's own construction (NGI's AdminVector spec §6.1 builds municipalities from Statbel sectors) and the only route at this vintage, since NGI keeps no archive and Statbel's Geographic files are sectors only. Union area equals the sum of the parts to within 2e-5 m² over 30,689.65 km², and the code set is exactly the Census 2021 CD_REFNIS_LVL_4 enumeration in both directions. This is a VINTAGE-PINNED companion to the current 565-municipality boundary, not a replacement for it.
