Changes to the NSW population occur due to a combination of births, deaths and migration.

These drivers of population change include:

  1. overseas migration
  2. internal migration gain
  3. internal migration loss
  4. high fertility rate
  5. ageing population




Components of population growth in NSW

Each year we take the number of births, minus the number of deaths, to get the natural increase of our population.


We also include net migration figures for NSW, which includes:

  • net overseas migration:the balance of people moving to NSW from overseas, or leaving NSW to move overseas for a year or more
  • net interstate migration:the balance of people moving to NSW from other places in Australia, or leaving NSW for other places in Australia.




While natural increase in our population has been quite steady over time, net overseas migration has always fluctuated. In recent years, people moving from overseas have become a big driver of population growth in NSW. Net interstate migration has also fluctuated, with an ongoing trend of more people leaving NSW for other areas in Australia than those who have been coming to NSW from other states.
