Mid-2024 · the data zone with the most people
Verified against source, 1 November 2026, 12:17 UTC3,780 small areas on Northern Ireland's data zones of 2021, too many to chart. Each area's figures are on its council's page, under Small areas, with every other dataset's for the same council; the councils are listed below. The whole file is in the CSV and JSON.
The hub keeps each figure on the area its file gives, never moved onto another year's areas. An area is found under the council the ONS's output area lookups put it in, or for Scotland and Northern Ireland the area register; an LSOA of 2011 that ended in 2021, which no lookup of today holds, under the council its own file names. 3,780 of the 3,780 are under a council with a page.

Notes
- The usually resident population at the 30th of June, on Northern Ireland's data zones of 2021, as NISRA's small area estimates give it, each rounded to the nearest person on its own, so the zones need not add up to Northern Ireland exactly.
- NISRA's matrix names its responsible statistician in its notes; the stored file leaves that line out, since the Open Government Licence does not cover personal data.
