ESTIMATION OF INDIGENOUS MORTALITY WHERE DESIGNATION OF INDIGENOUS STATUS ON DEATH CERTIFICATES IS UNRELIABLE

与其他澳大利亚人和其他类似国家的土著少数民族相比，土著澳大利亚人的死亡率高得令人无法接受。土著人死亡率是根据西澳大利亚州、南澳大利亚州和北部地区的数据计算的，尽管有些数据不可靠。在Qld、NSW、维克或Tas，几乎没有可靠的数据，因为死亡证明上的土著身份记录严重不足。这项研究的目的是设计和验证间接方法，以估计土著人占很大比例的次级人口的土著死亡率，而在这些次级人口中，在死亡证明上指定土著身份是不可靠的。这将有助于评估昆士兰州、新南威尔士州、维克和可能还有塔斯的大量土著和托雷斯海峡岛民社区的死亡率差异和趋势，并通过比较死亡率相对较高和相对较低的社区，为研究土著人口死亡率的决定因素提供新的视角，并通过监测死亡率趋势和差异，对服务和方案的有效性进行基于人口的评估。这些方法所依据的基本前提是，一个人口的总死亡率是由其各组成部分的死亡率相对于其在总人口中所占比例所造成的。分析单位主要是市镇。土著人的死亡率和比例将用于与具有类似社会经济和地理特征的城市进行比较，并将利用这些人口的各种特征，包括土著人的比例（使用澳大利亚统计局的数据），对各城市的死亡率进行统计建模。方法将采用选定的WA，SA和NT死亡率数据，其中指定的土著staus被认为是可靠的。然后将对新南威尔士州、昆士兰州和其他州的土著社区进行死亡率估计。

Mortality of indigenous Australians is regarded as unacceptably high compared to other Australians and compared to indigenous minorities in other similar countries. Indigenous mortality is based on data from WA, SA and NT, although some of the data are unreliable. There are few reliable data available in Qld, NSW, Vic or Tas because Indigenous status is significantly under-recorded on the death certificate. The objective of the research is to devise and validate indirect methods for estimating indigenous mortality in sub-populations where there are significant proportions of indigenous people, and where designation of indigenous status on death certificate is unreliable. This would permit assessment of mortality differentials and trends in a significant number of Aboriginal and Torres Strait Islander communities in Qld, NSW, Vic and possibly Tas and provide new perspectives in the study of determinants of mortality in indigenous populations through comparisons of communities with relatively high and relatively low mortality, and allow population-based evaluation of the effectiveness of services and programs through surveillence of mortality trends and differentials. The methods rely on the basic premise that the total mortality of a population is contributed to by the mortality of its components in relation to their proportion of the total population. The units of analyses will be mainly municipalities. Mortality and proportion indigenous will be used in the comparison of municipalities with similar socio-economic and geographic characteristics, and mortality by municipality will be statistically modelled using various characteristics of these populations, including proportion indigenous (using ABS data). Methods will be validated by employing them on selected WA, SA and NT mortality data where designation of indigenous staus is considered reliable. Mortality estimates will then be made for indigenous communities in NSW, Qld, and other states.
