National Growth Areas Alliance (NGAA)

SEIFA - disadvantage by small area

In 2011, Shire of Serpentine Jarrahdale had the lowest level of disadvantage in the National Growth Areas Alliance (NGAA), with a SEIFA index score of 1,047.2.

The National Growth Areas Alliance (NGAA) SEIFA Index of Disadvantage measures the relative level of socio-economic disadvantage based on a range of Census characteristics. It is a good place to start to get a general view of the relative level of disadvantage in one area compared to others and is used to advocate for an area based on its level of disadvantage.

The index is derived from attributes that reflect disadvantage such as low income, low educational attainment, high unemployment, and jobs in relatively unskilled occupations.  When targeting services to disadvantaged communities, it is important to also look at these underlying characteristics as they can differ markedly between areas with similar SEIFA scores and shed light on the type of disadvantage being experienced.

A higher score on the index means a lower level of disadvantage. A lower score on the index means a higher level of disadvantage.

The percentile column indicates the approximate position of this small area in a ranked list of Australia’s suburbs and localities. It’s meant to give an indication of where the area sits within the whole nation. A higher number indicates a higher socio-economic status. For instance, a percentile of 72 indicates that approximately 72% of Australia’s suburbs have a SEIFA index lower than this area (more disadvantaged), while 28% are higher.
