The standard measure of composition of a group within a country or a region is its headcount relative to the overall population. However, the headcount ratio of a given group ignores the age-based variability of its population with respect to the whole population. In this paper, a measure capturing the groups' age-wise distribution is proposed, which can be useful for policymakers in identifying potential demographic distortions experienced by population subgroups. An empirical exercise on the Australian Census data for the years 2006, 2011 and 2016 provides the age-distributed composition of the Indigenous population in the states and territories of Australia.

澳大利亚土著人口的年龄分布构成

衡量一个国家或地区内群体构成的标准衡量标准是其人数相对于总人口的比例。但是，给定群体的人数比例忽略了其人口相对于整个人口的基于年龄的变异性。在本文中，提出了一种衡量群体年龄分布的方法，这有助于政策制定者识别人口亚组所经历的潜在人口扭曲。对 2006 年、2011 年和 2016 年澳大利亚人口普查数据的实证研究提供了澳大利亚各州和领地土著人口的年龄分布构成。
