Why the caveats matter

Every figure carries the publisher's own caveats. Where a statistic is published for a wider area than the one you clicked, or where the publisher itself flags it as unreliable, the page says so rather than quietly rounding it off.

The UK's four nations publish separately, so some figures stop at a border: house sale prices cover England and Wales, road collisions Great Britain. Pupil absence is published for England, but not every English district individually — some are reported only as part of their wider county. An area with fewer datasets isn't missing data — either its nation publishes that statistic through a different body, or (pupil absence only) its own district isn't reported separately.

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.
