HOUSEHOLD AND DWELLING CHARACTERISTICS, 2003–04
Australian households are becoming smaller on average. However, the size of the houses or apartments (dwellings) that people live in, is increasing (as indicated by the number of bedrooms). The average number of persons per household declined from 3.1 in 1976 to 2.5 in 2003–04. In the same period, the proportion of dwellings with 4 or more bedrooms increased from 17% to 27% and the average number of bedrooms per dwelling rose from 2.8 to 3.0.
In 2003–04, most households enjoyed relatively spacious accommodation. For example, 85% of lone person households lived in dwellings with two or more bedrooms. More than three-quarters of 2-person households (77%) had three or more bedrooms. Nearly one-third of 3-person households (31%) had four or more bedrooms. More than a fifth (22%) of 3-bedroom dwellings, and 8% of 4-bedroom dwellings, had only one person living in them.
Dwelling characteristics have an impact on the environment in terms of the amount of energy needed to heat and/or cool them and the amount of resources used to build or renovate them. Other things being equal, a larger house will consume more energy than a smaller one, although factors such as solar orientation can alter this equation.
