EXPLANATORY NOTES INTRODUCTION 1 This publication contains preliminary estimates at June 2000 of the resident population by age and sex in Statistical Local Areas (SLAs) of NSW. ESTIMATED RESIDENT POPULATION 2 The estimated resident population (ERP) is the official Australian Bureau of Statistics (ABS) estimate of the Australian population. 3 The ERP of an area (State, SLA, etc.) is the estimate of the number of persons who usually reside in that area irrespective of where they were at the date of the estimate. METHODOLOGY 4 The total population of each SLA is based on results of the 1996 Census of Population and Housing. Post-Census population estimates are calculated with a linear regression model which uses independent indicators of population change such as dwelling approvals and Medicare enrolments. However, as no direct measure of population movement for SLAs is available, the indicators may give an incomplete picture. Therefore, it should be noted that all intercensal estimates will be subject to revision when final results are available from the 2001 Census. 5 Post-censal estimates of the age and sex distributions of SLA populations are made by updating the age/sex profile at the Census using annual births (by sex), deaths (by age and sex) and a derived age and sex profile of migration. While annual data on births by sex and deaths by age and sex are available for each SLA, data on migration into and out of SLAs for post-censal years are not available, and have to be derived indirectly. 6 After each Census, final estimates for the proceeding intercensal period are calculated by incorporating an adjustment (intercensal discrepancy) to ensure that the total intercensal increase at each age agrees with the difference between the estimated resident population at the two respective census dates. 7 A detailed explanation of the concept of, and of method of calculating, the ERP is contained in the ABS Information Paper Population Estimates: Concepts, Sources and Methods (Cat. no. 3228.0). STATISTICAL AREAS OF NSW 8 This publication contains data presented according to the Australian Standard Geographical Classification (ASGC) and incorporating changes brought about by the (State) Local Government Act 1993 to the titles of local government areas (LGAs). Under this classification, statistical areas are defined as follows:
9 Further information concerning statistical areas is contained in the publication Australian Standard Geographical Classification (Cat. no. 1216.0). BOUNDARY CHANGES 10 For the purposes of this publication, all data refer to bounded areas as defined at 1 July 2000 and as incorporated in ASGC 2000. 11 A list of name changes, amalgamations and boundary changes of SLAs and other statistical areas of NSW, from 1 July 1999 to 30 June 2000, is contained in the Appendix. ROUNDING 12 Estimates for each age and sex category are shown to the nearest unit without rounding, although accuracy to this level is not claimed and should not be assumed. This procedure is consistent with 1987 to 1996 age and sex estimates, and is applied because rounding of small cells could result in substantial year to year fluctuations owing to the rounding process rather than an actual population change. 13 Population estimates in previous publications have been rounded as follows:
ABS DATA AVAILABLE ON REQUEST 14 In some cases, the ABS can also make data available on request. This information may be made available in one or more of the following forms: floppy disk, CD Rom, photocopy, computer printout, clerically-extracted tabulation. Generally, a charge is made for providing data on request. Inquiries should be made as shown in the inquiries section at the front of this publication.
