URBANISATION AND URBAN SPRAWLUrbanisation involves the movement of people

from rural areas to cities and is measured as the percentage (or proportion) of a country’s population living in cities.

Urban sprawl involves the constant spreading out of cities through the growth of new suburbs. The more planning that goes into the growth of cities, the better urban sprawl can be managed. As cities grow there needs to be careful consideration given to the development of essential infrastructure.
