How this table is built

Median asking rent per calendar month of residential lettings in the month, from the area_facts listing rollup. Asking, not achieved.
Each place's 12-month figure is the monthly medians weighted by their sample; a place with fewer than 30 lets over the year is not ranked.
measured: a sample of at least three times the floor; indicative: at least the floor.
Ties share a rank and order by sample.
Twelve months for every place; no monthly point is ranked.
No monthly point is ranked: a postcode district records a handful of sales a month, and a month-on-month change there is noise.
