HDB statistics, facts & figures

Since its founding in 1960, HDB built 1,200,402 dwelling units and commercial properties by end-2018. Beside HDB, SIT built about 23,000 units between 1927 and 1959, HUDC built about 9,600 units in 1970s and 1980s, and JTC built somewhere around 10,000 – 20,000 units in 1960s and 1970. This makes around 1.25 million public housing units built.

Of them, 1,063,250 dwelling units are in use at 31 March 2018 according HDB Annual Report, about 130,000 dwelling units being demolished (clearance of rental blocks and SERS), converted (2 units joined into 1 unit), privatized (HUDC), etc. About 20,000 – 30,000 are commercial units.

According Database of HDB blocks in Excel format, including under construction blocks launched until November 2018 BTO and demolished blocks after 2010, there are 1,148,936 units in 10,645 blocks, averaging 107.93 units per block.

Biggest HDB towns:
Current town boundaries were introduced in Annual Report 1990. Bedok was the biggest town, overtaken by Tampines in 1996 then by Jurong West in 2000. We expected Sengkang to take the lead, but after announcement of Tampines North estate in 2013, adding under construction flats to the flats in use as 31 March 2018 make Tampines leader again (in 2021 we expect these flats to be completed to make Tampines leading in flats in use), Jurong West, Sengkang and Woodlands are in close battle.

According SingStat, as 2018 the Singapore population is 5,638,700, of which 3,994,300 Residents (3,471,900 Singapore Citizens and 522,300 Permanent Residents).

According HDB Annual Report 2018, 3,247,500 Residents live in HDB apartments, this means 81% (non-residents are not allowed to own HDB apartments but they can live in apartments owned by a Resident spouse, also they are allowed to own apartments in private condominiums taller than 6 storeys but not landed houses or apartments in low-rise condominiums). This means average family size of 3.1 residents per apartment and 30 sqm per person. Note that HDB Annual Report shows same resident population since 2015 onward, based on older Annual Reports 2010-2014 average household size was around 3.4 residents per apartment so 27 sqm per person. For comparison, in 1968 were in average 6.2 people per apartment (average flat size I estimate around 40 sqm).

Many HDB owners are renting rooms or entire flat to foreigners, some HDB owners are citizens married with foreigners, HDB never provide official statistics about how many non-Residents does live in HDB apartments.

According Yearbook of Statistics 2010, Singapore population including non-residents is 5,076,700 living in 1,180,500 dwelling units (HDBs, condos, private flats, landed houses, others), of which 76.3% are HDBs, this means a nationwide average of 4.30 people per dwelling unit, if the average would be same for HDB, it would mean 22 sqm per person (no newer statistics available for non-residents).

Average household size for each flat type and race can be seen on www.singstat.gov.sg > Key Indicators and Sample Household Survey. You can see that households with 6 or more persons represent 10% of Chinese households and 23% of Malay households.

Home ownership of HDB flats reached the peak of 94% in 2002, then slowly felt down to 90% in 2011 and been constant to 2018.


This table shows number of Resident households by type (HDB, condo, landed, etc). As 2017 there are 1,018,600, 201,700 condos, 66,500 landed, 3,100 other Resident households. Non-Resident households are not included here (many condos are owned by foreigners).

Number of units in private condominiums, executive condominiums, square meters of office and retail space, can be seen in https://www.ura.gov.sg/uol/media-room/news/2017/Apr/pr17-30 and https://www.ura.gov.sg/uol/-/media/User%20Defined/URA%20Online/media-room/2017/pr17-06e1.pdf

Total residential dwellings 1,370,319, private residential landed 72,595, non-landed 275,485 (2016) according https://www.singstat.gov.sg/docs/default-source/default-document-library/publications/publications_and_papers/reference/sif2017.pdf (page 16)

Despite of shrinking flat sizes in late 1990s, average flat size has increased until 2005, reaching about 95 sqm, thanks to demolition of small 1/2/3-room flats built in 1960-1970s and building 90-140 sqm flats, also due to Main Upgrading Programme that add 5 sqm utility rooms. After 2005 average flat size is slowly falling down because HDB stopped supply of Executive, reduced supply of 5-room, and reintroduced 1-room, 2-room and 3-room flats. As 2018, average flat size of existing flats stock is 93.02 sqm.

New flats launched via BTO since 2011 and completed from 2015 onward are about 80 sqm in average, for comparison the flats build in mid-1990s were about 120 sqm in average, a world record for public housing. Read more: HDB Flat Size analysis.

Sources:
SingStat for the population.
HDB Annual Reports for the number of flats (units).
HDB Resale Flat Prices database 2013-2017 (89538 records) for estimating average size of each flat type.

The average flat size may be a bit inaccurate because the resale flat prices database include only sold flats, there is no info about the size of rental 1/2-room flats, and does not include flats built last 5 years which are under minimum occupation period, which are smaller than average size of older flats.

HDB flat size statistics based on resale transactions

I have database of HDB Resale Flat Prices 1990-2017 and analyzed data in Excel. Here are the results:

As country level: the average flats size is 95.45 sqm (average of 767528 transacted units).

As town level: Pasir Ris New Town (built between 1988 and 1996) have the biggest flats, 123.62 sqm (average of 28469 units) Central Area (most built in 1970s) have the smallest flats, 71.52 sqm (average of 5893 units).

As neighborhood level: Pasir Ris 2XX neighborhood have the biggest flats, 132.74 sqm (average of 4363 units), Pasir Ris 5XX have 129.24 sqm (average of 4689 units), Pasir Ris 6XX have 126.89 sqm (average of 2742 units), Choa Chu Kang 5XX have 125.87 sqm (average of 3363 units), Tampines 3XX have 122.58 sqm (average of 6022 units).

Note that the average size of resold flats is slightly bigger than the real average flat size, because the big and <10 year old flats tends to change their owners more frequently than the small old flats owned mainly by elderly, also some of the small flats are rented from HDB rather than owned, so they never appear in resale transactions.

    you provide more information than HDB does! what you did is amazing.
    want to check with you whether you have included figures from HDB annual report 2011. seems the total units they provided is 1,011,027 units instead of 901,971 units you have above.

    1. Because over 100,000 units were demolished or adjoined. You confuse number of flats EVER BUILT with the number of flats CURRENTLY under management.

    Hi,
    Do you also study the HDB BTO construction price. E.g the construction cost ($/m2) for each unit type basing on the contract awarded price to the Main Contractor.

    Regards,
    Serina

    1. The above statistics are sourced on Annual reports, Resale flat prices, and Singapore Statistics… do you saw any source of data providing cost of building HDB? Personally I never saw… this looks like a government secret!
      There are rumors that is 1/2 or 1/3 of selling price. But HDB subsidy upgrading programmes, they should get money for this someway, this may justify pricing new flats higher than construction cost.

    Hi, out of the 900,000 over HDB flats, do you know how many are rental flats? I tried to browse or make sense of the figures but came out nought?

    1. Look inside Excel file https://www.teoalida.com/singapore/HDB-Statistics-by-Teoalida.xls > scroll down to 2014 (since 2012 I started copying in Excel breakdown by sold and rental) or in http://www.hdb.gov.sg/fi10/fi10320p.nsf/w/AboutUsAnnualReports?OpenDocument > Key statistics > Dwelling units under management
      Answer: 872411 sold + 52318 rental in as 31 March 2014.

    Awesome job!!
    May I know if you have any data for number of planned HBD from 2016 – 2020? Something like HDB in pipeline?

    1. There is an image on https://mndsingapore.wordpress.com/ showing number of units that will be COMPLETED next 3 years, does it help?
      If you’re asking number of BTO flats planned to be LAUNCHED, we will see in november exact projection for 2016, and the projection is likely to be based on the BTO application ratio, probably another 15.000 flats like this year, or less if they take in consideration falling prices.
      For the next 15 years there is a contradiction between an article from 2013 http://www.stproperty.sg/articles-property/singapore-property-news/700000-new-homes-by-2030-too-many-or-too-few/a/103220 and the current HDB trends to reduce BTO supply.

  1. […] THE TRUTH: average size of all types of NEW flats, has been shrunk from 125 sqm for flats sold in mid-1990s to 78 sqm for BTOs launched in 2010 and rose to 83 sqm for BTOs launched in 2012, thanks for high applicant ratio for 5-room and reducing distribution of 2/3-room. Average size of all housing stock is around 95 sqm. […]

  2. […] 4 room HDB households able to be powered annually: 2,404,624,277 / (5640 x 12) = 35,529 households Total number of HDB Dwellings in Punggol: 24,859 Number of years Punggol could be powered by savings: […]

  3. […] Total number of HDB Dwellings in Punggol: 24,859 […]

  4. […] more details, see HDB Statistics […]

  5. […] example, whilst the total number of HDB flats grew by 201,755 or 25,219 per year, in the eight years from 661,163 in 1994 to 862,918 in 2002 – […]
