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

Major migration assumptions:

  • Loss of population in most age groups, owing to little housing opportunity in the area to attract families or maintain population as families mature and children leave home. Housing opportunities tend to be accessed by households formed by people from the area resulting in negligible in-migration
  • A small gain over the period in established families with children aged 5-14 years, most particularly post 2016, as the area undergoes a small degree of regeneration. Gains in the parent age groups are volatile, fluctuating between gains and losses, with gains in 30-39 year olds in the earlier period and 30-39 years in the later period
  • Losses in all other age groups
