The published record for this corner: measured numbers with their receipts, named absences where the record is empty. No scores, no forecasts, nothing invented.
The app draws this corner’s buildings, shows it on the island map, checks a rent you were quoted against this record and runs your own numbers.

How to read a row: the bold figure is the middle of its range and the figures either side are the range’s ends; “carried” means aggregated up from finer measurements (streets, postals, doors) into this corner, never a direct reading at it. The n is the count behind the figure: contracts, awards, units or taps, by instrument. An absent row carries a code and a side, never an instrument or a date, because nothing was measured. Every rent row was measured per square metre a month by its publisher (URA’s street medians, HDB’s awards over their printed floor area, the portals’ asks) and is printed here per square foot, divided once by this record’s own bridge of 10.76 sqft per sqm.
suppressed_at_source: withheld or not published at source. GHS 2025 printed a dash for this cell — small counts are withheld to prevent identification of individuals, and suppression is not a population of zero. The dash is denser in the age x sex strata than in the pooled total, which is what suppression of small cells looks like and is itself information
suppressed_at_source: withheld or not published at source. GHS publishes no usable dwelling mix for this subzone — SingStat printed a dash, which its own footnotes define as nil OR negligible OR suppressed — three different worlds one glyph cannot distinguish, so this is recorded as the publisher withholding, never as zero. The household count here is the same divide as the spend weights, and with no residents-by-dwelling there is nothing to divide
not_published: withheld or not published at source. GHS 2025 C020148 publishes no workplace figure for this planning area — small workforces are not itemised, and an unpublished area is never a workforce of zero. The no-fixed-location (201,500) and work-from-home (82,200) categories also sit outside every area, so even the published figures are floors.
not_yet_wired: a gap on OUR side of the pipeline. no commercial-rent fact, valued or absent, reached this subzone, and an unexplained gap is ours by rule
not_yet_wired: a gap on OUR side of the pipeline. no hdb-tender fact, valued or absent, reached this subzone, and an unexplained gap is ours by rule
not_yet_wired: a gap on OUR side of the pipeline. no residential-rent fact, valued or absent, reached this subzone, and an unexplained gap is ours by rule
no_shopfront_zoned: withheld by our own rule. The figure is published one grain up and not placed here. District 11 stamps a Level 1 (street level) shop-space band of S$8.67–27.68 psf, and this corner is outside the market it describes: under the Master Plan 2025 with amendments, no parcel in this subzone is zoned for a use a ground-floor trade can occupy. The plan does not permit a shopfront here. The land here is open space (63% of 65 parcels). Rather than dress a corner with no room for a shop in its district's shop rent, the band is withheld. The district figure is real, its placement here is not. Zoning is permission, not supply: this is the plan's refusal, never a count of shops.

A zone URA changes after this date is not in this figure until URA publishes the layer again and this figure is rebuilt
URA PMI district median at DISTRICT grain, not measured at this corner. 38% of this corner's geocoded postals sit in District 11. That is a plurality, not a majority: this corner straddles districts and no one district holds more than half of its 8 postals, so the district named here is the largest minority. The stratum is Level 1 (street level), declared here because URA stamps no all-levels, all-bands district median: the 2 size bands pool UNWEIGHTED: lo the lowest of the bands' lows, hi the highest of their highs, mid the median of band medians, because URA publishes no contract counts to weight with; n=3 is its disclosure floor, not a sample size. Read the bands and match your own floor area.

ENTRIES AND EXITS SUMMED on an average weekday, all day. Not boardings: a reader who takes it for boardings is out by roughly half. Each station carries ITS OWN measured weekday taps and its own measured distance to this corner. Nothing is re-allocated and no share is invented, so a station that serves several corners appears on several cards. Distance is straight-line from this corner to the station's NEAREST PUBLISHED EXIT (LTA, 613 exit points), not to a representative address, and not a walking route: the real walk is longer wherever a road, canal or rail line stands in the way, and an underground link reads as its street doorway. Every station within 400m is listed, busiest first. The radius is the only cut. Where an interchange spans two codes the taps are summed and every code is named.

NEA lists NO hawker centre in this corner. Its registry is a census of 129 centres, each carrying its own point, and every one of them was placed (none fell outside a subzone), so this is a measured zero rather than a corner nobody looked at. The nearest is Sembawang Hills Food Centre (Jalan Leban Food Centre), 130m from this corner's edge, and it is named for the same reason the nearest station is: a centre just over the boundary is not a centre that does not exist, and a straight "none here" would be a binary answer to a continuous question. Straight-line to its published point, not a walking route, and no claim is made that it sits in this corner.
nea.ssot.hawker-centres · subzone grain · as of 2026-03-13 · 2026-03-13 is NEA's own last-refresh stamp (FMEL_UPD_D) on the freshest row in this registry extract, not a survey date. A measured zero is only as current as the census behind it, and this is that census's date
suppressed_at_source: withheld or not published at source. GHS publishes no usable dwelling mix for this subzone, so the bridge has no weights: a dash that means nil OR suppressed, and a bridge without weights would be the national number wearing a subzone's name. What is withheld is the dwelling MIX: a resident population may still publish above
not_published: withheld or not published at source. SingStat publishes the GHS 2025 household income distribution by PLANNING AREA and names 29 of them; CENTRAL WATER CATCHMENT is not one, so the households here sit inside the table's "Others" row together with 25 other planning areas. That row is an aggregate, not a place, and splitting it would mean inventing a share nobody published. This is the publisher pooling a small resident population, never a statement that households here earn little or that nobody counted them.

Counted as shopfront-capable: commercial, commercial & residential, residential with commercial at 1st storey, white, business park - white, hotel.
no parcel in this subzone is zoned for a use a ground-floor trade can occupy. The plan does not permit a shopfront here ZONING IS PERMISSION, NOT SUPPLY. This is the share of this corner's zoned land whose use class can hold a shopfront (COMMERCIAL, COMMERCIAL & RESIDENTIAL, RESIDENTIAL WITH COMMERCIAL AT 1ST STOREY, WHITE, BUSINESS PARK - WHITE, HOTEL) under the Master Plan 2025 with amendments. Not floor space that exists, not units for rent, and not a promise any particular unit is licensed for your trade. A low share means the plan gives a shopfront little room here; a high share does not mean anything is built. Each parcel is counted whole in the subzone holding its centroid.
