dont be so sure http://www.smartcompany.com.au/economy/20100615-the-big-picture-will-the-size-of-australia-s-average-household-really-shrink.html from the article ""Why the difference? Well the assumption is that the number of people occupying dwellings will ease over the 25-year period from 2.6 people per household to around 2.4-2.5 people. That may not sound like much, but it adds up over time. But actually the decline is far less significant than the previous forecasts that had tipped household size to fall to around 2.2-2.3 people per household by 2026. On that assumption, Australia would have needed to build far more (but smaller) homes over coming years.""
