Short name:	PI02b-Proportion of Indigenous babies born within the previous 12 months whose birthweight results were low, normal or high, 2020–2021
METEOR identifier:	717271
Registration status:	Health, Retired 13/10/2021 Indigenous, Superseded 14/07/2021
Description:	Proportion of Indigenous babies born within the previous 12 months whose birthweight results were categorised as one of the following: Low (less than 2,500 grams) Normal (2,500 grams to less than 4,500 grams) High (4,500 grams and over).
Rationale:	Low birthweight (newborn babies weighing less than 2,500 grams) is associated with an increased risk of ill health and is related to higher mortality within the first year of life. Low birthweight is a particular issue for Indigenous Australians. Recording birthweight encourages the provision of appropriate care to limit the negative associations of low birthweight.
