Transaction volume
The count of registered sales in an area and period, read straight from HM Land Registry Price Paid rather than from a matched sample.
Also called: sales volume, number of sales, transaction count.
Definition
Transaction volume, as the data uses it
"How many homes sold in SE22 last year" is a registry question, and MarketCode answers it from the registry: every registered sale, monthly, from 1995, for a postcode district, postcode area or county. The market cube's own count is a UPRN-matched sample that runs well short of the registry, so the platform reads counts from one place and prices from the other and says which.
Volume is market size, not liquidity. The busiest districts are the largest ones; for "where do homes sell fastest" use turnover. And read the provisional date before the trend: the trailing months are incomplete because of registration lag.

- Turnover rate: Sales in a period as a share of the dwellings that could have sold; the liquidity measure, distinct from the raw count of sales, which measures market size.
- Registration lag: The weeks to months between a sale completing and HM Land Registry registering it, which makes the most recent months of any sold-price series incomplete.
