Computation description:Help on this term

Low birthweight is defined as less than 2,500 grams.

Excludes multiple births and stillbirths. 

Analysis by state/territory, remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) is based on usual residence of the mother.

Data excludes Australian non-residents, residents of external territories and records where state/territory of residence was not stated.

Variability bands are to be calculated for single-year and aggregate years data by state and territory using the method below.

Presented as a:

  • percentage, and 
  • number (Indigenous status).
Computation:Help on this term(Numerator ÷ Denominator)

 

Variability bands: to be calculated using the standard method for estimating 95% confidence intervals as follows:

Crude rate

 

The 95% Confidence Interval Formula

 

Where d=the number of low birth weight live-born singleton infants.

Numerator:Help on this termNumber of low birthweight liveborn singleton infants.

Disaggregation:Help on this term

2010—Nationally by:

  • remoteness (Australian Standard Geographical Classification Remoteness Structure)
  • SEIFA Index of Relative Socio-Economic Disadvantage (IRSD) quintiles and deciles

2010—State and territory, by:

  • Indigenous status

2008–2010—State and territory, by:

  • Indigenous status

Disaggregation by Indigenous status is recommended to be reported using three-year combined data for the current reporting period due to the small number of low birth weight infants born to Indigenous mothers each year. Single year data (2010) will be reported for time-series (state/territory by Indigenous status).

Comments:Help on this term

Most recent data available for 2013 Council of Australian Governments (COAG) Reform Council (CRC) report: 2010 (calendar year data).

Indigenous: Aggregated data (2008 to 2010) will be reported for the current reporting period (state and territory).

Single year data (2010) will be reported for time-series (state and territory).

Information is included in the National Perinatal Data Collection (NPDC) for all live births and still births of at least 400 grams birthweight or at least 20 weeks gestation. Indigenous status of infants is currently only available based on the Indigenous status of the mother.

For further detailed analysis by Indigenous status see the National Indigenous Reform Agreement (NIRA) report.
