Why is the population so low in central Australia? There is an abundance of rainfall in this area.

There are too many resources for the people to pick from.

The land is too hilly for people to settle there.

The climate is too hot and dry in the desert.

The real reason is due to economics but I’d go with D.

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
