Computation description:Help on this term

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

Excludes multiple births, stillbirths and births with unknown birthweight or unknown gestational age.

Analysis by state/territory, remoteness and SEIFA Index of Relative Socioeconomic 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.

Presented as a:

  • percentage, and 
  • number (Indigenous status).

Disaggregation:Help on this term

2009—Nationally by:

  • remoteness (Australian Standard Geographical Classification Remoteness Structure)
  • SEIFA Index of Relative Socioeconomic Disadvantage (IRSD) deciles

2009—State and territory, by:

  • Indigenous status

2007–2009—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 (2009) will be reported for time-series (state/territory by Indigenous status).

Comments:Help on this term

Most recent data available for 2012 CRC report: 2009 (calendar year data).

Indigenous: Aggregated data (2007 to 2009) will be reported for the current reporting period (state and territory).

Single year data (2009) 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.
