1 This product contains estimates of the resident population by age and sex of Statistical Local Areas (SLAs) at 30 June 2003.
2 To meet the conflicting demands for accuracy and timeliness there are three estimates of sub-state/territory populations, preliminary, revised and final. The estimates in this product are preliminary. The 2003 SLA totals contained in this product differ slightly from previously released SLA totals due to revisions to births and deaths data for March and June quarters 2003.
3 In recognition of the inherent inaccuracy involved in population estimation, population figures in accompanying text and summary tables are generally rounded. While unrounded figures are provided in the main tables, accuracy to the last digit is not claimed and should not be assumed.
ESTIMATED RESIDENT POPULATION
4 The concept of ERP links people to a place of usual residence within Australia. Usual residence is that place where each person has lived or intends to live for six months or more from the reference date for data collection.
5 In census years the ERP as at 30 June for each SLA is based on usual residence census counts, with an allowance for net census undercount and the number of residents temporarily overseas at the census date. Overseas visitors in Australia are excluded from this calculation. As the 2001 Census was held on 7 August, further adjustments taking into account births, deaths and net migration for the intervening period are made to obtain the ERP at 30 June.
6 Population estimates by age and sex for post-census years are obtained by advancing the census-year estimates to the next age, subtracting deaths and adding births and net estimated inter-regional and overseas migration.
7 A more detailed explanation of the concept and method of preparing ERP, as adopted by the ABS for official population estimates, is contained in Demographic Estimates and Projections: Concepts, Sources and Methods, Statistical Concepts Library, available on the ABS web site.
AUSTRALIAN STATISTICAL AREAS
8 The geographic areas used in this publication are defined and published in the Australian Standard Geographical Classification, 2003 Edition (cat. no. 1216.0). A complete set of maps showing the SLAs mentioned in this product is freely available on the ABS web site by selecting About Statistics.
