Average Aboriginal life expectancy
Aboriginal people can expect to die more than 10 years earlier than non-Aboriginal Australians. On average, Aboriginal males live 67.2 years, 11.5 years less than their non-Aboriginal peers, women live 72.9 years, 9.7 years less .
Aboriginal life expectancy is so low because Aboriginal health standards in Australia are now so bad that 45% of Aboriginal men and 34% of women die before the age of 45. 71% die before they reach the age of 65. 
According to the United Nations, the quality of life of Aboriginal people is the second worst of the planet—only China rates worse .
I always say that when we lose an old person, we lose a library… language and culture.—Lola Forester, Aboriginal radio presenter 
Comparing Aboriginal life expectancy is difficult
Comparing Aboriginal life expectancy across countries is notoriously difficult. Each country has different methodologies how it counts its Aboriginal citizens. Australia estimates figures based on self-identification, New Zealand by ethnic group membership, the USA if people live on or near reservations, and Canada counts “Registered Indians”.
Consequently, it is difficult to justify drawing many conclusions regarding cross-country differences.
The following comparison is based on data published by Bramley et al. in 2004 . Bramley evaluated data from 2000–2002.
The average life expectancy of Australian Aboriginal people is 59.5 years and has remained steady between 1990 and 2000 . American Indians and Alaskan natives lived an average of 70.8 years over that period. Canadian Aboriginal people lived an average of 72.8 years, Maoris 71.1 years.
Newer data calculated by the Australian Bureau of Statistics (ABS) yields a smaller gap between Aboriginal and non-Aboriginal life expectancies. This is because in 2008, the ABS has introduced a new method for calculation. While the underlying method to process the data remained the same, the method for accounting for under-identification of Aboriginal deaths changed.
Using this new method, the average life expectancy for Aboriginal people is 70 years .
Why live Aboriginal people shorter lives?
Causes for a low life expectancy include:
- poor health and nutrition - Research found that about 80% of the life expectancy difference is due to preventable chronic conditions, such as type 2 diabetes and cardiovascular disease ;
- poor housing,
- dispossession of their traditional lands,
- low education level,
- high unemployment,
- hidden racism, and
- inability of politicians to address Aboriginal problems.
We are still living in pain and trauma. We are in pain already and more and more pain is falling on top of us. It makes us feel weaker and weaker. People are getting sick, tired and stressed. —Yalmay Yunupingu, Aboriginal artist and teacher 
“Adequate primary health care services can bring about dramatic results,” says former Social Justice Commissioner Tom Calma .
The life expectancy of native Americans increased by about 9 years, between 1940 and 1950, after such services were provided. The life expectancy of Maori in New Zealand increased by 12 years from the 1940s to the 1960s, attributed to the same reason.
Australian life expectancy figures might be all wrong
While the life expectancy figures presented above are bad news by themselves, the truth might be even worse which has led to the Australian Bureau of Statistics (ABS) to adjust its methodology in 2009.
Is the life expectancy gap larger?
According to academics, 50% of death forms filled out by undertakers don’t identify if the deceased is of Aboriginal descent or not .
We can't really even track changes to say yes, things are on the way up or no, they're getting worse.—Prof Tony Barnes, Charles Darwin University
With no accurate statistics on the number of Aboriginal people dying each year it is impossible to calculate Aboriginal life expectancy and any progress on closing the life expectancy gap.
Two estimates of Aboriginal life expectancy in 2008 differed by as much as five years, providing contradictory messages on the magnitude of the life expectancy gap and rendering any mortality rate calculation unreliable .
Hence the Australian Bureau of Statistics had to use a ‘semi-theoretical’ approach for its calculations and has done so since 1996 because census results are ‘unreliable’.
The 20-year life expectancy gap which was identified in 1973 might still be there, but no-one knew for sure or could tell if it has widened instead.
Really, there's no change [of the life expectancy gap].—Prof Len Smith, Australian Demographic and Social Research Institute
A new methodology to calculate the life expectancy gap
Consequently, in May 2009, the ABS introduced a new methodology to “better compensate for a significant undercount of Indigenous death records” .
The new “experimental figures” released by the ABS show the life expectancy gap has narrowed , from 20 years previously to approximately 10 years.
A gap of either 10 or 17 years is utterly unacceptable in a country like Australia that prides itself on a fair go for all.—Tom Calma, Aboriginal and Torres Strait Islander Social Justice Commissioner
