Up till 1990, Singapore’s population projection was less than 4 million by 2030. Even the URA 1991 Concept Plan projected a 4 million population.
According to a 1990 Singapore Medical Association article, “Singapore – An Ageing Society“, by P W J Choo, K S Lee, R E Owen and F J Jayaratnam, PAP had anticipated our total population to be only 3.21 million by 2030.
Infrastructure construction is planned around a target population, not the other way around as PAP has been doing for more than 2 decades.
Expectedly, infrastructure has recently started to fall apart/severe shortage after 2 decades, eg MRT system, hospitals, road congestion, etc.
Although PAP has increased infrastructure construction – an afterthought – there are limits because our population has already exceeded by almost 50% of the projection more than 2 decades earlier.
As we head towards 6.9 million, more severe consequences are to be expected.
There is obviously only one way to avoid more tikam-tikam planning by PAP.

The worst is that 40% of the over-population is made up of foreigners treating S’pore as hotel. Most are from 3rd world countries & they can’t be if the infrastructure goes down the toilet. They just interested to collect their monthly salary and bonuses. After 10-20 years working here, they F off back to where they came as retired or semi-retired landowners & business owners.
