The Australian Bureau of Statistics (ABS) produces demographic estimates and projections. Each of these estimates and projections employ the concept of residency which links people and households to a place of usual residence within Australia.
This publication provides a description of the concepts, sources of data and methods used by the ABS. Chapter 1 gives an overview of the range of population estimates published by the ABS and outlines the reasons why population estimates are produced. Chapter 2 and Chapter 3 provide a description of the methods and the data used to produce the population estimates at National/State levels and sub-State levels, respectively, as well as their accuracy. (Throughout the publication references to States also include the Northern Territory and the Australian Capital Territory unless otherwise stated.) Chapter 4 deals with the sources and quality of the data used in population estimates. Chapter 5 looks at household estimates while Chapter 6 explains population projections with a reference to household and family projections due to be published for the first time by ABS in late 1999. The appendices provide more technical detail.
