Suicide drop a result of unsuccessful attempts

By calculating the rate of suicide attempts and deaths by the most common methods, the University of Melbourne researchers found lethality declined by 57%, from 12% of all attempts resulting in death in 1994 to 5% of attempts resulting in death in 2007.

Furthermore, the researchers were able to account for at least some of the increase in attempt failures, including changes to catalytic converters in motor vehicles which have reduced carbon monoxide emission levels.

“This study identified changes in method-specific lethality as a critical driver of Australia’s decline in suicide deaths since 1997,
