The record

How many HDB resale flats were registered in Sengkang in August 2019?

August 2019.

Ledger rows whose subject key names this town (keys from sg:hdb:SENGKANG|), whose attribute is resale_price_sgd, and whose observed month is 2019-08. Each registration seals one such row, so this counts registrations, not re-reads.

Against the last month

The two figures are the same. Both figures come from the same read, asked of each window.
