, Indirect Cost per single youth suicide was multiplied by Total Years of Productive Life Lost (YPLL). The correct calculation should have been Indirect Cost per single youth suicide multiplied by Total Number of Suicides (not YPLL). This led to an overestimated Total Indirect Cost and Total Cost of Youth Suicide in Australia reported in the paper. Following further suggestion by a reviewer, we aligned the wording under Section 3.2 and Section 3.3 (i.e., Productivity Loss and Bereavement) with the terms used in tables (i.e., Indirect Cost and Intangible Cost).

In the abstract, the sentence regarding the Total Cost should be as follows: The total economic loss of youth suicide in Australia is estimated at $511 million a year (equivalent to US$ 352 million), ranging from $460 to $586 million. Abstract should read as follows.

 

Abstract: Suicide is the leading cause of death among Australians between 15 and 24 years of age. This study seeks to estimate the economic cost of youth suicide (15–24 years old) for Australia using 2014 as a reference year. The main outcome measure is monetized burden of youth suicide. Costs, in 2014 AU$, are measured and valued as direct costs, such as coronial inquiry, police, ambulance, and funeral expenses; indirect costs, such as lost economic productivity; and intangible costs, such as bereavement. In 2014, 307 young Australians lost their lives to suicide (82 females and 225 males). The average age at time of death was 20.4 years, representing an average loss of 62 years of life and close to 46 years of productive capacity. The average cost per youth suicide is valued at $2,884,426, including $9721 in direct costs, $2,788,245 as the value of lost productivity, and $86,460 as the cost of bereavement. The total economic loss of youth suicide in Australia is estimated at $511 million a year (equivalent to US$352 million), ranging from $460 to $586 million. These findings can assist decision-makers understand the magnitude of adverse outcomes associated with youth suicide and the potential benefits to be achieved by investing in effective suicide prevention strategies.

displays the consequences of a single youth suicide by age and sex. The indirect cost as the loss of economic productivity attributable to each suicide averaged $2.8 million in 2014 dollars, ranging from $1.9 million for females aged 20–24 to $3.2 million for males aged 15–19. The intangible cost represented by the average cost of bereavement was estimated at $86,460. The direct economic cost per suicide was $9721.

3.3. Total Economic Cost of Youth Suicide

The total economic cost of youth suicide in Australia was estimated at $511.1 million (in 2014 AU$) per year, of which the indirect cost was the largest cost accounting for 94% (Table 4). The amount of indirect costs was estimated at $481.6 million. The cost of bereavement (intangible cost) was the second largest cost of $26.5 million. Direct costs accounted for just under $3 million.

considers the cost by means of suicide. Threat to breathing, including hanging, suffocation by putting a plastic bag or pillow over one’s head, and intentional drowning, accounted for more than 14,105 YLL and more than $384.6 million of the total cost of suicide. Blunt force, such as jumping from a height, person moving in front of a moving object, such as a train or motor vehicle, and motor vehicle crash, was the second largest method of suicide among youth accounting for 2195 YLL and $59.9 million. Piercing and penetrating force, including shooting with firearms and stabbing with a knife or other sharp instruments, claimed 907 YLL and just under $25 million of the total cost of suicide in 2014.

Proportion of youth that employed
Baseline = 56%	$511,108,097
Sensitivity 5 = 65%	$585,921,731
Funeral cost
Baseline = 4000	$511,108,097
Sensitivity 6 = 15,000	$514,485,097
Discount rate used to convert future costs to present value
Sensitivity 7 = 4%	$580,352,099
Baseline = 4.58%	$511,108,097
Sensitivity 8 = 5%	$468,868,306

provides results of the sensitivity analysis. The baseline cost of suicide of $511.1 million ranged between $460.0 and $585.9 million. The largest deviation related to the proportion of youth being employed (Sensitivity 5) and the theoretically reduced number of suicides per year (Sensitivity 1). For example, a reduction in youth suicides by 10% could potentially alleviate the economic burden by up to $51.1 million per year including $298,421 ($0.3 million) in direct costs, $2.7 million as intangible, and $48.2 million as indirect costs.

4. Discussion

The economic cost of youth suicide in Australia is estimated at $511 million a year ($460–586 million) in 2014 AU$. Direct costs account for $3 million (1% of the total cost); indirect costs at $482 million (94%); and intangible costs at $27 million (5%).

The cost of suicide increases by age cohort, from $192 million (for 15–19-year-olds) to $317 million (for 20–24-year-olds). This increase is attributable to the higher prevalence of suicide among 20–24-year-olds (12.0 per 100,000) compared to 15–19-year-olds (7.4 per 100,000). It is also worth noting that the cost of male youth suicide is significantly higher than the cost of female suicide ($406 million versus $102 million, respectively), again due to higher prevalence of suicide deaths in the former group (14.0 versus 5.4 per 100,000 population, respectively). Threats to breathing are the most common cause of death regardless of the age or gender and account for over $385 million (75%) of the estimated total cost.

Although the effectiveness of this approach is yet to be established, our findings suggest that the impact of meeting a 10% reduction in youth suicide could potentially save many lives and over $51 million a year, including $298,421 ($0.3 million) in direct costs, $3 million as intangible and $48 million as indirect costs.

5. Conclusions

An average of 319 young Australians take their lives each year at an economic cost of $511 million.

Other Corrections:

In Table 1, the average weekly earnings for females were $940 and for males—$1430.
