Methodology
Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
13 of the 28 named sources that could be read published a usable figure; 15 published none and are recorded as not published, never filled in; 4 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 165 candidate sentence(s) were refused by a reviewer with the reason recorded.
The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): levy = Schedule 3 rate for the authority x chargeable floorspace (GIA), halved where at least 75% of the site is previously developed land; the national spread (County Durham lowest, Kensington and Chelsea highest), the median rate and the rate per region; each council page checked against Schedule 3
165 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
