Collection and usage attributes
Low birthweight is defined as less than 2,500 grams.
Excludes multiple births, stillbirths and births of less than 20 weeks gestation.
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:
100 × (Numerator ÷ Denominator)
Variability bands: to be calculated using the standard method for estimating 95% confidence intervals as follows:
CI (CR)95% = CR ± 100 × 1.96 × √[((CR/100) × (1 – (CR/100)))/n]
Where n=number of live born singleton infants.
CI = confidence interval
CR = crude rate (expressed as a percentage)
Number of low birthweight live born singleton infants.

Disaggregation by Indigenous status of the mother and the baby are 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, and the small number of low birth weight Indigenous infants born each year. Single year data (2014) will be reported for time-series (state/territory by Indigenous status).
Note that data collection methods for Indigenous status of the mother and baby may vary between states and territories. Disaggregation by Indigenous status of baby will only be available if the National Indigenous Reform Agreement Performance Information Management Group determine that the data are of sufficient quality.
|Disaggregation data elements:|
Most recent data available for 2017 National Healthcare Agreement performance reporting: 2014 (calendar year data).
Indigenous: Aggregated data (2012 to 2014) will be reported for the current reporting period (state and territory).
Single year data (2014) 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. Data for this indicator may therefore include live born terminations of pregnancy of at least 20 weeks gestation.
For 2014 data, the 2011 SEIFA IRSD quintile and decile data will be produced using the ASGS geographical unit of Statistical Area Level 2.
