HDB statistics, facts & figures

Since its founding in 1960, HDB built 1,182,539 dwelling units and commercial properties by end-2017. 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 1.2 million public housing units built.

Of them, 1,047,350 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.

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.

    re.number of blocks built before 1990.


    The $5 billion LUP for older HDB blocks is 14 years old and the programme ended last December. It provided a lift on every floor to 5,000 blocks built before 1990.

    Could you tell me how many people the HDB employs. I am interested in getting public authorities in London to pay close attention to what the HBD has achieved and an indication of the scale of the HDB in terms of the numbers of people it employs and net annual expenditure required to meet its costs of operation would be very helpful to me, Thanks in anticipation for any help you can give.

    1. http://www.hdb.gov.sg/cs/infoweb/about-us/news-and-publications/annual-reports here you can find some financial info, but we will never able to know how many people it employs.

  1. We’re having coffee at Nylon Coffee Roasters on Everton Park in Singapore.

    I’m having black coffee, he’s developing a cappuccino. He is handsome.
    Brown hair slicked back, glasses that suited his face, hazel eyes and the prettiest lips I’ve seen. He’s nice, with incredible arms and also a chest that sticks out
    within this sweater. We’re standing in front of one another speaking about our everyday
    life, what we would like into the future, what
    we’re trying to find on another person. He starts telling me that he’s been rejected
    many times.

    ‘Why Andrew? You’re so handsome. I’d never reject you ‘, I only say He smiles at
    me, biting his lip.

    ‘Oh, I really don’t know. Everything happens for a good reason right.
    But figure out, would you reject me, would you Ana?’ He said.

    ‘No, how could I?’ , I replied

    “So, you would not mind if I kissed you currently?’ he said as I get nearer to him and kiss him.

    ‘The next time don’t ask, just do it.’ I reply.

    ‘I love how we think.’ , he said.

    For now, I start scrubbing my calcaneus as part of his leg, massaging it slowly. ‘What can you prefer in ladies? And, Andrew, don’t spare me the details.’ I ask.

    ‘I really like determined women. Someone that knows what they have to want. Someone that won’t say yes even though I said yes. Someone who’s unafraid when you attempt something totally new,’ he says. ‘I’m never afraid when trying something mroe challenging, especially when it comes to making new things in bed ‘, I intimate ‘And I like females who are direct, who cut with the chase, like you merely did. To generally be
    honest, that is a huge turn on.’

  1. […] The likeliest reason for this is a nearly all-encompassing system of public housing. A striking 82% of Singaporeans live in public housing built by the government, and comprehensive programs exist to supplement meager […]

  2. […] It’s not all palm-lined beaches: Lichtenstein and Luxembourg are both landlocked states, after all. And the realities of life crowd in even on small island locations. The average three-bedroom house in Jersey costs £527,000, compared with £209,000 in Torquay. On average, houses in the Isle of Man cost twice as much as those in the north-west of England. The fact is that if those with wealth pay less tax they push house prices out of the reach of most people. No wonder 82% of all Singaporeans live in state-owned housing, most of which is flats. […]
