How to read flatlas

Reading the map

• Zoom changes the detail. Zoomed out, each town is coloured by its median price over the last 12 months. Zoom in and every block appears as a dot; closer still, blocks rise in 3D, coloured floor by floor by what sold on those storeys.
• Colour means price. One colour scale runs from cheaper to dearer at every zoom level, and the legend shows what each colour stands for.
• Lens switches what the colour shows: price, price per square metre, remaining lease, rent, rental yield, or (for towns) five-year price growth.
• Today's dollars or as paid. Prices are adjusted for inflation by default, so different years compare fairly; switch to see the price recorded at the time.
• Sale or rent. The same map for HDB rentals since 2021.
• Tap a town or block for its prices by flat type, sales history, what the price model says it is worth and why, nearby MRT stations and schools, and whether you could afford it.
• The tools on the right: Layers (MRT stations, primary-school catchment rings, childcare centres), Budget (shade every block by whether it fits your budget), Saved (blocks you have starred, on this device) and Filters (flat type, minimum lease).
• Share any block: the link opens the map on it, with its panel open.

Price pages

Every figure on the map also exists as a plain page, for reading, linking or citing: all towns ranked by price, each town and each of its flat types, every street and every block with enough sales. How these figures are computed explains each one.

Where the data comes from

HDB resale and rental records, inflation (CPI), building and land-use data come from data.gov.sg under the Singapore Open Data Licence; block locations and public-transport routes from OneMap. Nothing is collected from listings or agents, and nothing you enter in the tools leaves your device.
