12-month suicidality and self-harm prevalence among 12 to 17-year-olds
About these maps
These maps visualise synthetic estimates of 12-month prevalence of suicidality and self-harm (for 2019) among 12 to 17-year-olds. Twelve-month prevalence refers to the prevalence of having experienced suicidality and self-harm at some point during the preceding twelve-month period. Each of the study suicidality and self-harm outcomes are visualised within a separate map.
Interpreting these maps
For these maps, variation in synthetic estimates has been visualised using percentiles. For example, those areas with the darkest colouring fall within the >90th percentile group, meaning that the 12-month prevalence of suicidality and self-harm was higher in those areas than 90% of all other areas in Australia.
Synthetic estimates are available in these maps at SA3, SA4 and PHN areas.
Darker colouring indicates that an area has a higher estimated prevalence of suicidality and self-harm, while lighter colouring indicates lower estimated prevalence. Grey colouring indicates that an estimate was not generated for that area due to insufficient data. This is mostly areas where few or no people live.
The data can be viewed at different geographies using the ‘Geographic View’ or the ‘Zoom View’. More detailed instructions on using the ‘Geographic View’ are included below.
These maps show
- Large variability across the country for self-harm (regardless of intent), non-suicidal self-harm, suicide attempt, suicidal ideation/plan, and suicidality.
- The Northern Territory had the highest prevalence of self-harm (regardless of intent).
- A possible trend towards increasing prevalence with increasing remoteness. However, a sparsity of Young Minds Matter (YMM) survey data for more remote areas meant that estimates for some more remote areas were not able to be generated. As such, the possible relationship between the suicidality and self-harm prevalence and remoteness cannot be fully assessed.
The ‘Geographic View’ allows users to select the type of area (i.e. SA3, SA4, PHN, State) that data are aggregated to, as well as the type of area for which geographic boundaries are displayed. For example, a user may choose to view data for a suicidal or self-harm prevalence outcome aggregated to SA3 areas, but with PHN boundaries displayed. In this view, the user can visually inspect the variability between SA3 areas within each PHN.
To do this the user selects only SA3 from the ‘Geographical Boundary’ menu and only ‘PHN Level’ from the ‘Suicidality and Self-Harm Prevalence’ menu within the mapped product. Click the triangle next to the menu title to expand and collapse the options for each menu. Then ensure only ONE option is selected from each menu. When the eye icon is open the option is selected. When the eye icon has a diagonal line through it, the option is not selected. Click the eye icon to select and deselect options.
The eye icon directly next to both the menu titles should be open.
