This is the word for word paragraphs mentioned by WP in the WP paper in 2019:
Resident population growth has been approximately 30,000 a year since 2010 and 2011. Assuming an average household size of 3.3, this would mean that around 9,000 or so new dwelling units are required annually. Completions within the same time period have far exceeded the resident population growth. Private vacancies have only started to inch down, but there are still around 12,000 private units completing up to 2022. Will the HDB have a vacancy rate problem, compounded by a still steady stream of 16,000 to 17,000 BTO units in the last few years, which will continue to increase supply up to 2022?
BTO projects should continue, but, rather than creating too many new towns, planners would do well to consider, in future, partly meeting demand from new family formation by selling balance flats in mature estates acquired under the Universal Sale and Lease Back scheme or USB (see previous chapter). This would help advance urban renewal in the mature estates where many Singapore [sic] desire to live, since these are nearer to the city centre.
