Notes on the data: Potential years of life lost, by selected cause

Potential years of life lost from deaths of persons aged 0 to 74 years, by selected cause, 2013 to 2017

 

Policy context:  As noted for premature mortality, above, some 34% of all deaths over the years 2013 to 2017 occurred before 75 years of age, although the proportion varies by sex and by cause, as shown here

However, depending on the age at which a person dies, the number of years of life lost had they lived until, say, 74 years of age will vary. Potential years of life lost (PYLL) is a measure of the sum of the potential years of life lost from deaths at 15 years (60 years), 45 years (30 years) and so on, assuming they had all lived to 74 years of age.

The Australian Institute of Health and Welfare note that, on this measure, a particular PYLL value will be higher if mortality among children or young people is high; chronic diseases causing death among the elderly, on the other hand, have little effect on these values [1]. In Australia, there were 881,528 PYLLs on average over the five years 2013 to 2017, almost two thirds of which were for males (62.5%) and over one third for females (37.5%) [2]. This number represents a decrease of 90% from 1907, when there were 382 PYLLs per 1,000 population, to 2017, when this figure was 38 PYLLs per 1,000 population [1].

Some notable variations shown by the data for the five years 2013 to 2017 [2] are:

  • the highest rates were recorded for cancer (12.5 PYLLs per 1,000 population), with the range between the States and territories from 11.3 PYLLs per 1,000 population in the Australian Capital Territory and 11.8 in Victoria, to 15.0 in Tasmania PYLLs per 1,000 population and 16.1 in the Northern Territory;
  • the second highest rates were from external causes (9.5 PYLLs per 1,000 population), ranging from 6.9 in the Australian Capital Territory to 21.1 in the Northern Territory;
  • the rate of PYLLs for the people who lived in the most disadvantaged areas was more than four times that in the least disadvantaged areas across Australia for diabetes (4.54 times) and chronic obstructive pulmonary disease (4.74); and
  • for those living in the Very Remote areas, PYLL rates were 8.67 times those in the Major Cities areas for diabetes and 6.79 times for road traffic injuries – the variation between the States and Territories for diabetes ranged from 1.59 in Victoria to 7.78 in the Norther Territory, while for road traffic injuries it ranged from 2.11 in the Northern Territory to 8.76 in New South Wales.

    Notes:  For detailed data files released since 2007, the ABS has applied a staged approach to the coding of cause of death which affects the number of records available for release at any date. In each release, the latest year’s data are preliminary, the second latest are revised and the data for the earlier years are final. In this way, the majority of records are released earlier than would be the case than were no data released until files had been returned from Coroners’ offices.
