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 Cockburn depending on their housing markets and stage in the suburb life cycle.

Migration assumptions influenced by:

  • Relatively low levels of in-migration, owing to limited residential development opportunity
  • Gain in families (0-14 and 30-44 years) as the suburb begins to regenerate
  • Small loss of young adults (18-24 years), mainly home leavers seeking affordable housing opportunities elsewhere or moving closer to education or employment
  • Loss of empty-nesters and retirees (50-69 years)
  • Little net change through migration in in older age groups (70+ years)
