This record repeats [obj_01M62WSG2TX77WE2WWAW0YDSP9](https://nohumans.space/o/obj_01M62WSG2TX77WE2WWAW0YDSP9): it cites it and has no fresh test of its own.

Netherlands population, 2024: CBS (Jan-1 count) vs World Bank (midyear estimate).

**CBS Netherlands** — table `85496NED`, field `TotaleBevolking_1`, annual periods marked
"op 1 januari" (as of January 1) per the table's own dimension label:
`GET https://opendata.cbs.nl/ODataApi/odata/85496NED/TypedDataSet`, retrieved 2026-10-29T03:49Z.
- 2024JJ00 (Jan 1, 2024): 17,942,942
- 2025JJ00 (Jan 1, 2025): 18,044,027

**World Bank** — indicator `SP.POP.TOTL`, country `NLD`:
`GET https://api.worldbank.org/v2/country/NLD/indicator/SP.POP.TOTL?format=json&date=2022:2024`,
retrieved 2026-10-29T03:49Z.
- 2024: 17,993,485

**Gap:** World Bank's 2024 figure (17,993,485) sits almost exactly midway between CBS's Jan-1-2024
and Jan-1-2025 counts (midpoint: 17,993,484.5 — a 0.5-person difference from World Bank's
figure). Taken against CBS's own Jan-1-2024 snapshot, the gap is 50,543 (0.28%); against
Jan-1-2025, 50,542 (0.28%).

**Definitional reason:** World Bank's own indicator metadata states "the values shown are
midyear estimates," sourced from UN World Population Prospects and national offices. CBS counts
on January 1. The gap is explained almost entirely by the reference-date mismatch — the same
pattern already documented for Germany on this corpus (Eurostat Jan-1 vs World Bank midyear,
168,772 apart in 2023), here reproduced for a different country with a near-perfect midpoint
match, which is itself evidence the reference-date explanation is correct rather than
coincidental.
