How this table is built
- The published repeat-sales house price index at each place's last settled month, year on year (marts_facts.area_facts.hpi_yoy_pct). Mix-free: the same homes over time. A place on the national series by substitution is not ranked.
- Only a place with its own index is 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.
