How the figures are worked out
Census percentages on this site are calculated from the raw household counts in each table, for Liverpool and for England and Wales, and rounded to one decimal place (two for the very small renewable figures). The listed-building grades are counted from the individual records in the national planning dataset that fall inside the city boundary. The conservation area dates are the designation dates in the same dataset; one area has no date there.
The map
The city map is drawn directly from three planning datasets: the local authority boundary, the council's 36 conservation areas, and the point location of every listed-building record. The shapes are simplified slightly so the page stays light, but nothing has been added or moved by hand. Contains public sector information licensed under the Open Government Licence v3.0; listed-building data originates with Historic England.
Two counts that differ
The census counts households on one day in March 2021; the off-gas estimate counts domestic properties with gas meters in 2024; the grant statistics count installations paid for up to September 2026. They measure different things at different times, so the guide uses each for what it measures and does not mix them in one calculation.
If something has changed
Councils and departments update their pages without notice. If a source now says something different from this guide, the source is right; please tell us through the form so the page can be corrected and its check date updated.
