Deaths among adults aged 25–44

There were 5,112 deaths among people aged 25–44 in 2012 and this equates to a rate of 79 deaths per 100,000 population aged 25–44, or 1 death per 1,267 people. The death rate decreased by 29% since 1997, from 111 deaths per 100,000 to 79 deaths per 100,000 (Figure 7.1).

More than two-thirds (69%) of deaths in this age group are considered potentially avoidable, including all of the top 5 causes of premature mortality.
