What impact does the population density of Western Australia have on urban growth?

The population density of Western Australia significantly influences urban growth patterns. In this context, the correct choice, which suggests that high population density limits urban expansion, reflects the geographical and socio-economic dynamics at play.

Western Australia, particularly its more remote regions, has a low overall population density compared to many other states or territories. This limited density often results in urban areas that are not as populous as major cities in more densely populated regions. With fewer people spread out across vast areas, there is less pressure for these urban centers to expand extensively.

Moreover, the geographical characteristics of Western Australia, including significant distances between towns and the presence of large uninhabited spaces, further contribute to limiting urban expansion. When population density is low, the demand for housing and infrastructure in urban areas decreases, which in turn restricts the growth of urban environments.

This means that instead of developing densely populated urban centers or sprawling metropolitan areas, the region may experience growth that is slower and more measured. Thus, the correct answer appropriately captures the relationship between population density and urban growth dynamics in Western Australia.
