What these terms mean
- Mid-year estimate
- A modelled count of the population on 30 June, updated between censuses. It is an estimate, not a headcount. Source
- Local authority district
- The council area a statistic is published for -- 361 across the UK. In England these are boroughs, districts and unitary authorities; in Scotland, council areas; in Wales, principal areas; in Northern Ireland, districts.
Before you use these figures
- Mid-year estimate, not a census count: This is a modelled mid-year (30 June) estimate, not a direct headcount. It is rebased periodically against the latest UK census results -- the current series was rebased to the 2021/2022 censuses, replacing previously published estimates for 2011 to 2022. Figures for the same year can therefore change between publications as later data becomes available.
- Unrounded, but not precise to the individual: Figures are published unrounded to enable further calculation, but ONS is explicit that small estimates should not be read as accurate to a specific person -- they are produced using statistical models and disclosure-control methods, not a direct count.
- Not adjusted for population: This figure — 584,296 — is well outside the typical range for other areas currently publishing this dataset (median about 148,095 across 349 other areas). This is a raw count, not adjusted for population — a larger area is expected to report a larger number regardless of anything unusual happening there. Not itself a sign of a data problem.
- Not adjusted for population, 2024: This area's 2024 figure was 578,432, well outside the typical range for other areas that reported for 2024 (median about 148,242 across 360 other areas). This figure is a raw count, not adjusted for population — a larger area is expected to report a larger number regardless of anything unusual happening there. Not itself a sign of a data problem.
