Data coverage register for a local authority
data_coverageThe data-coverage register for a local authority — read it before the data: per-field non-null and source shares over every unit in the authority (floor area, bedrooms, year built, EPC, last sale, tenure…), which designation flags were checked and how fully, how many units carry a registered lease or a hereditament, whether official planning data covers the authority and how deep it goes (applications, link shares, latest decision), and how much of the live listing stock the sweep has dated. `area` is a GSS code (E09000032), a local authority name (Wandsworth) or a warehouse area id. State the coverage before quoting a share from a thin field. UK only.
