How it is made
Open Index shows the figures as Councils, Historic England and MHCLG publishes them, for the areas they were published for: map points.
Larger areas use the publisher’s own figures, never an average of smaller areas.
Before you use it
- This is the national dataset on planning.data.gov.uk, which its publishers call a work in progress and incomplete. Some councils have not supplied their conservation areas, and those councils are hatched on the map.
- Where a council has no data of its own, Historic England's records are used if they exist. They may be older or less exact than the council's.
- The dataset holds some duplicate areas. Where two outlines are at least 80% the same shape, Open Index draws the better one.
- About 950 conservation areas have a name but no outline in the national dataset. They are not drawn.
- A hatched council may still have conservation areas. It means the outlines are missing here, not that none exist.
- England only.
