Migration is one of the most important components of population change. Once you have established the amount of development activity in an area, the next step is to make assumptions about who will move into the area as well as who is leaving the area.

Net migration by age is an excellent way of understanding housing markets. The most mobile age groups in the population are young adults. They tend to move to attend educational institutions, seek work and express a change in lifestyle. Market research has shown that empty nesters are more likely to move to smaller accommodation when appropriate and affordable alternative housing is supplied in the local area that is accessible to established social networks.

Select each small area to see how migration patterns differ for each area across City of Tea Tree Gully depending on their housing markets and stage in the suburb life cycle.

Migration assumptions influenced by:

  • Some new housing opportunities remaining in the north of the City in the short and mid-term with longer term opportunities developing in the southern part of the City, both which are expected to attract predominantly young couples, young and maturing families
  • The loss of young adults aged 18-24 years leaving home is expected in many areas, as the trend of young adults leaving the City to find employment and education opportunities elsewhere in Adelaide and interstate continues, however Tea Tree Gully also retains some residents in this age group due to availability and affordability of housing for those students who commute to Adelaide
  • A loss of older families is expected as opportunities to upgrade within the City are limited
  • There is a slight gain of elderly residents who may move here from other parts of Greater Adelaide or outside the metropolitan area for proximity to healthcare and aged care services
