Derry City and Strabane council area. Every figure carries its own date.
ONS, NRS and NISRA via Nomis
Official source →Published annual mid-year population estimates, both sexes. Exact requested ONS area code; source geography vintage retained. Latest revised source series is used throughout; no years are interpolated and no ward values are inferred.

The download includes 3 source response receipts, with dates and content hashes.
UK census offices via Nomis
Official source →Direct official census counts for the exact requested geography code. Native table category labels retained. Shares use this table’s own total; privacy-adjusted cells may not sum exactly to that total. The 2011 UK table retains its own category structure, including a separate Traveller category. It is not automatically comparable with later national census categories or modern district boundaries.

Official source →First count table only in the LGD and NI worksheets. Shares calculated using All usual residents in the same row. Northern Ireland’s 2021 native ethnicity categories are retained. Counts are for current Local Government Districts, not reconstructed historical districts. Different tables can differ slightly because of census privacy protection.

Dates and area boundaries matter. A council-area total is not automatically a city total. Missing observations stay missing; they are never treated as zero.
A city identity and its wider local authority are different geographies. Shared-authority cities reuse the same authority evidence and must display its full scope.
Missing/suppressed/failed observations remain null with a reason; they are never replaced by another city or zero.
Survey, census, administrative records and population estimates retain distinct evidence types.
Scottish crime counting rules and annual periods differ from Police UK street-level mapped crime. No common UK ranking is produced.
Census periods differ between nations: England/Wales and Northern Ireland 2021, Scotland 2022.
Source checking and automated validation are not independent analytical review or AQuA certification.
Interpretations are derived from the same official figures supplied in this package; no alternative figures are typed into the page.
Ward contrasts require matching source, measure, period, units and boundary vintage. Ranges describe only wards with available comparable figures; no mean of ward percentages is calculated.
Differences between percentages are percentage points. Neighbourhood comparisons are descriptive, not causal claims, personal risk scores or proof of service performance.
Recent changes require an observation from exactly one year earlier. Long-run comparisons retain their actual endpoints and source definition; cash housing values are not adjusted for inflation.
Proposed responses and delivery questions are analysis, not a claim that a council has approved funding, adopted a policy or completed work.
The three nearest other official UK cities, measured in a straight line between the official representative place points, not by road or ferry distance. Cities across national borders are included. The same council area is not counted twice. These are geographical neighbours, not a ranking of similar economies or services. Each figure is compared only when its period, definition, unit and source are compatible. The national reference is the origin city's own nation, not an average of the selected cities.
The comparison uses the council areas named beside each figure. Distances are between official city location points, not road distances. Missing or incompatible figures stay visible with an explanation.
See the local and national comparisons →This work follows principles from the AQuA Book: transparent sources, proportionate checks, uncertainty and reproducible calculations. Automated and agent checks are not independent analytical assurance or certification.
Interpretations and proposals are labelled separately from official commitments. Source-change monitoring produces review candidates; it does not automatically approve publication.

Checked 2026-10-17. Global no-crime-data notices and missing latest-month crime reports suppress complete-period comparisons. Historical missing-crime notices are tracked chronologically until an explicit later crime refresh covers that month. Unresolved historical notices preserve observed rows but block trend interpretation. Stop-and-search and outcomes notices are not treated as crime omissions. UK Facts separately flags unexplained source discontinuities without asserting their cause.
