The City of Onkaparinga

Migration by age and location

Between 2016 and 2021, the LGA with the highest net migration to Port Noarlunga South (+1,395) was from Marion, whilst the highest net loss (-466) was to Mount Barker.

The age structure of people who move into and out of the City of Onkaparinga is strongly influenced by the residential role and function of the area and can influence demand for particular services. For instance, inner city areas near employment, education and entertainment tend to attract many young people in their late teens and early twenties, who move out in their late twenties and thirties to start families in suburban areas. Rural areas tend to lose young people and gain older families and retirees.

Understanding the City of Onkaparinga's attraction to different age groups helps to plan services for the community as well as advocating with other levels of government and private enterprise to provide infrastructure, employment opportunities and facilities which may help to retain age groups which are otherwise leaving the area.
