Suburbanization is a term used to describe the growth of areas on the fringes of major cities. Sudden and extreme relocation out of urban areas into the suburbs is one of the many causes of urban sprawl, as suburbs grow to accommodate the increasingly large population.

Where is suburbanization most evident?

The preponderance of suburban growth is evident in high income world metropolitan areas. For decades, nearly all growth in nearly all cities has been in the suburbs. Some notable examples are London, Toronto, San Francisco, Portland, Tokyo, Zürich, and Seoul.

What is suburbanisation and when did it occur?

Suburbanisation. This is where the suburbs on the outer edge of the settlement grow outwards as new houses and services are built to accommodate more people. This type of expansion sees the settlement grow at the expense of surrounding green land.
