Birthweight recorded (PI01)
This indicator is the proportion of First Nations babies born within the previous 12 months who attended the organisation more than once and whose birthweight was recorded.
There have been changes to the specification of this indicator over time. For more information see Interpreting nKPI data.
Why recording birthweight is important
Birthweight is a key indicator of infant health and a principal determinant of a baby’s chance of survival and good health (AIHW and NIAA 2024). Measuring birthweight allows infants to be given early and suitable intervention, which can mitigate adverse outcomes.
At June 2025, 75% of (or around 5,700) First Nations babies born within the previous 12 months had their birthweight recorded (Figure 16).
The data visualisation below (Figure 16) shows, for each collection period from June 2017 to June 2025, the proportion of First Nations babies born within the previous 12 months whose birthweight was recorded. Select by either:
- organisation type
- remoteness
- state/territory
to see data for that breakdown.
Data tables supporting this visualisation are available at Data.
Figure 16: Birthweight recorded by collection period
Overall, the proportion of First Nations babies born within the previous 12 months whose birthweight was recorded generally showed little or no change between December 2022 and June 2025.
Notes
- In June 2021, specifications changed for this indicator. For more information see Interpreting nKPI data.
- Breaks are included to separate out the periods most affected by voluntary reporting and the peak of COVID-19 and associated emergency response measures. This break, however, is not a clean break as each indicator in the nKPI collection has an assigned time frame (a reference period) as part of its specification. For this indicator, which has a reference period of 12 months, data in the December 2022 collection period (covering 1 January 2022 to 31 December 2022) still overlaps with the peak of COVID-19 and associated emergency response measures. For more information see Comparisons over time.
- The linear trend lines provide a general impression of the direction of the data. Caution should be taken interpreting trends with less than 5 data points. See also Figure 13 for trends for selected data.
