Blue Mountains City Council

Net migration by age

The age group with the highest net migration in Blue Mountains City Council is 35-39 year olds, this is forecast to occur in the period between 2026 to 2031.

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 Blue Mountains City Council depending on their housing markets and stage in the suburb life cycle.

Major migration assumptions:

  • Limited new housing opportunities across the City, resulting in moderate population growth over the forecast period
  • Gain of young family households (0-9 and 30-39 year olds)
  • The loss of young adults in their late teens and twenties leaving home is expected in many areas, as some will leave the City to find employment and education opportunities in metropolitan Sydney
  • Minor gains of mature adults, empty-nesters and early retirees (44-64 years)
  • Loss of retirees and elderly aged 65-80 years
