The Number of Bedrooms in a dwelling is an indicator of the size of dwellings, and when combined with Dwelling Type information, provides insight into the role the City of Onkaparinga plays in the housing market. For example, an area of high density dwellings that are predominantly 1-2 bedroom are likely to attract students, single workers and young couples, whereas a high density area with dwellings that are predominantly 2-3 bedroom may attract more empty nesters and some families.
In combination with Household Type and Household Size, the Number of Bedrooms can also indicate issues around housing affordability, overcrowding and other socio-economic factors.
