Consequences of urbanisation in Australia and
the United States Urban areas are those that are permanent settlements and feature a range of built structures such as houses, commercial buildings, roads, bridges, railways and so on. They can range in size based on the population. The Australian Bureau of Statistics defines urban centres as having a population of 1000 people or more. Conurbations Sometimes there are so many cities in a particular region that they seem to merge almost into one city as they expand. A conurbation is made up of cities that have grown and merged to form one continuous urban area. Both the United States and, to a lesser extent, Australia have conurbations.
