This figure shows the rate of IPD in Indigenous children aged less than 5 years from 2002 to 2010, by age subgroups (less than 12 months, 12 to 24 months and two to four years). The rate of IPD in Indigenous children fluctuated over the period due to the smaller number of notifications from a smaller population; however, an overall decline in the rate of IPD has occurred in the less than 12 months and 12 to 24 months age groups. Whilst, the rate of IPD in Indigenous children aged two to four has shown a slight overall increase since 2002.
