by 17 working adults. By 2020, one elderly person will be supported by five working adults. And by 2030, it will be one elderly person supported by just over three working adults. A larger elderly population in the future would also mean increased public expenditure due to increasing demands on our public healthcare, community and social support infrastructure. Taxes may have to be raised to increase support for the aged. With fewer younger people, our workforce and society will lose our vitality and vibrancy. This will mean that Singapore will become less attractive to foreign investors. Our own young talented Singaporeans may leave our shores for better opportunities in more dynamic economies. With fewer young Singaporeans, we will face grave challenges to maintain the strength and efficacy of our citizen armed forces, security and law enforcement agencies. Sir, in a nutshell, we need 60,000 babies just to replace our resident population. But we only have about 37,000 babies per year. That is provided the number does not go down again in future. This is why I mentioned that we need about 20,000 new citizens in order to keep our citizen core. Unless there is a dramatic reversal of our local TFR, and I do not see this happening, it is critical that we must tap on immigration as a measured means to augment our population. We must continue to allow in good-calibre foreigners as PRs and SCs to supplement our low birth rates. However, our society needs a strong citizen core. Singaporeans must always form the bulk of our resident population. Hence, we must focus on getting good-quality citizens rather than carry a large PR population who are content to remain PRs indefinitely instead of taking up Singapore citizenship. Without this infusion of new citizens, based on the current demographic trends, we will soon have a shrinking population and a declining Singapore. Mr Chairman, Sir, I would like to assure this House that the Government is cognisant of the ground sentiments and feedback on the issues which had been brought about by immigration in recent years. We have made careful refinements and changes to our policies to address these concerns. But we have also to be practical and realistic. We must look at the issue of foreign workers and immigration objectively and rationally. We must recognise that good-quality foreign workers and immigration still remain important to our sustained economic growth and are vital to address our serious longer-term population challenges. Ultimately, the key is always in finding the right dynamic balance and trade-offs, as some MPs have suggested. This is not easy to do but it is necessary to do, if Singaporeans are to be assured of a future and a quality of life, no less than what we enjoy today. Sir, we are all descendants of immigrants. Singapore grew and prospered since its founding because our great-grandfathers, grandfathers, fathers or parents – I must say actually grandparents, great-grandparents, otherwise the women will take offence – were allowed to come and settle to make a better life and in the process, to contribute to Singapore's growth. Had they been denied the opportunity to do so at the right time, we would not be born here and Singapore would not be what it is today. In future, the children and the grandchildren of today's immigrants who sink roots here, will grow up with our children and grandchildren. Together, they will be the next generation of Singaporeans and Singapore will be their home, just as much as it is our home today. Mr Chairman, Sir, Singaporeans' concerns over the immigration policy are widely reported in the Chinese media. So please permit me to say a few words in Mandarin. well into our society. From the fourth quarter of last year, we have already tightened the framework. Going forward, we will further tighten the framework to raise the quality of the immigrants. This will reduce the number of PRs granted. As for new citizens, provided that they meet the quality criteria, we should take up to 20,000 a year. *Cols. 3031-3032.
