Notes on the data: Aboriginal premature mortality by selected cause

Deaths from respiratory system diseases, Aboriginal persons aged 0 to 54, 0 to 64 and 0 to 74 years, 2010 to 2014

 

Policy context:  Respiratory system diseases are those that affect the respiratory tract (upper airway, trachea, bronchus and lung). They include cancers of the respiratory system, chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), pneumonia, influenza and other respiratory diseases [1].

Respiratory system diseases are associated with a number of contributing factors, including poor environmental conditions, socioeconomic disadvantage, risky behaviour (particularly tobacco smoking, alcohol use, and substance use) and some previous medical conditions [2][3]. Infants and children are particularly susceptible to developing respiratory conditions, due to factors such as exposure to tobacco smoke, poor environmental conditions, and poor nutrition [2][3].

During 2008-2012, respiratory diseases caused 8% of all Indigenous deaths (888 deaths) [4]. Fifty-three percent were attributed to COPD, 4% to asthma and 19% to pneumonia and influenza. Aboriginal and Torres Strait Islander peoples die from respiratory system diseases at twice the rate of non-Indigenous people.

Deaths data

For deaths data 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. This release is comprised of preliminary data for 2014, revised data for 2013 and final data for 2010, 2011 and 2012. For further information about the ABS revisions process see the following and related sites: http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/3303.0Explanatory+Notes12012.

Data quality

Almost all deaths in Australia are registered. However, Indigenous status is not always recorded, or recorded correctly. The incompleteness of Indigenous identification (referred to as completeness of coverage) means that the number of deaths registered as Indigenous is an underestimate of the actual number of deaths which occur in the Indigenous population. It should also be noted that completeness of coverage is likely to vary between geographical areas.

While there is incomplete coverage of Indigenous deaths in all state and territory registration systems, some jurisdictions have been assessed by the Australian Bureau of Statistics (ABS) as having a sufficient level of coverage to enable statistics on Aboriginal and Torres Strait Islander mortality to be produced. Those jurisdictions are New South Wales, Queensland, South Australia, Western Australia and the Northern Territory.
