Migration, or residential mobility, together with births and deaths are significant components of population change in Australia. Migration is the most volatile component of population change and can be affected by changing housing and economic opportunities such as housing affordability issues or the mining boom. The three main types of migration are overseas migration, interstate migration and within-state migration, of which within-state is the most common and largely involves moves between neighbouring areas within an urban or regional setting.
Looking at the level and type of migration in the Southern Sydney Regional Organisation of Councils (SSROC) can indicate whether the population is sedentary and likely to be in the area for a long time (and perhaps have significant ties to the community), or transient, and likely to move on. Related topics which can be viewed to get a clearer picture of population mobility include Age Structure (young adults are likely to move more often) and Housing Tenure (generally renters move more often while home ownership indicates a more stable population).
This table shows the broad trends of movement between the Southern Sydney Regional Organisation of Councils (SSROC) and the states/territories of Australia, and from overseas over the 5 years from 2016-2021.
