How are Living Spaces getting smaller?

If you compare the government flats (or HDBs) built in the past and the new ones , you will find a significant decrease in size. I had previously visited some of the new government flats and new condominiums in Singapore and they were all much smaller than my current old government flat which is built in the late 1980s located in Pasir Ris. From the kitchen to the living room and to the bedroom, all of which are smaller than mine. My old flat is able to fit a 5-seater dinning table in the dinning room, whereas some new condominiums that i visited could hardly even fit a dinning table. All these were the result of land shortage and population growth, more people, lesser land, results in a shrink in size of the flat as governments and developers needs to fill in more people in a lesser area of land. With that, prices of land and apartments have also gone up significantly over the decades making it more difficult for young couples who wants to settle down and they are also on a really tight budget.
