Of all the reasons put forward to explain why Singaporeans are not having more children, I don't think I've come across one that beats this . The letter writer feels that HDB and private apartments are too small for people to have more children. Although the argument does concede that '... the size of an apartment is not the main reason for couples not having more children, but I am quite sure it plays a part', the point of the letter is that the apartments are too small and therefore they restrict the size of the family. I know that HDB flats today are smaller than those built, say, 20 years ago. As pointed out in the letter, people do decide to sell their smaller, newer flats and buy older, bigger ones. I'm sure it's a big hassle doing so, and then there are also financial and other considerations, but those aside, what's wrong with staying in an older but bigger flat? And as for the argument that siblings who share bedrooms get on each other's nerves...
