Rural-urban migration
The movement of people from rural areas (countryside) to urban areas (towns/cities)
Urban growth
An increase in the number of urban dwellers.
Classifications of urban dwellers depend on the census definitions of urban areas, which vary from country to country. They usually include one or more of the following criteria: population size, population density, average distance between buildings within a settlement and legal and/or administrative boundaries.
Urbanisation
An increase in the proportion of a country’s population that lives in towns and cities. 2 main causes:
1. natural population growth and
2. rural to urban migration
Greenfield site
This is an area which has not previously been built on – often in the rural urban fringe
Ribbon development
This is urban growth, and the expansion of suburbs, along routes into the CBD
Suburbanisation
This is the movement of people from living in the inner parts of a city to living on the outer edges. It has been facilitated by the development of transport networks and increase in car ownership. It results in a spread of the urban area.
Urban sprawl
The spread of an urban area into the surrounding countryside. This happens if there are no planning controls.
