Prices are medians of actual HDB resale transactions published by the Housing & Development Board through data.gov.sg, not estimates or an index. HDB reports by town rather than by postal district, so each figure is labelled with its town. Town-years with fewer than ten sales are omitted. Private housing transactions are not included.
