EXPLANATORY NOTES


INTRODUCTION

1 This publication contains statistics for births and fertility in Australia. Detailed information can be obtained from data cubes (in Microsoft Excel format) available for download from the ABS website (see paragraph 57).

2 A glossary is provided detailing definitions of terminology used. A list of abbreviations is also available.


SCOPE AND COVERAGE

3 Statistics in this publication relate to the number of births registered during the calendar year shown, unless otherwise stated. Statistics relating to births by year of occurrence can be obtained from


Scope of birth statistics

4 The ABS Birth Registrations collection includes all births that occurred and were registered in Australia, including births to mothers whose place of usual residence was overseas.

5 The scope of the statistics include:

• all births that were live born and were not previously registered;
• births to temporary visitors to Australia (including visitors from Norfolk Island);
• births that occurred within Australian Territorial waters;
• births that occurred in Australian Antarctic Territories and other external territories (excluding Norfolk Island);
• births that occurred in transit (i.e. on ships or planes) if registered in the state or territory of "next port of call";
• births to Australian nationals employed overseas at Australian legations and consular offices (i.e. children born overseas to Australian diplomats or their families); and
• births that occurred in earlier years that have not been previously registered (late registrations).

6 The scope of the statistics exclude:

• still births/fetal deaths (these are accounted for in perinatal death statistics published in Perinatal Deaths, Australia, cat. no. 3304.0 and previously, in Causes of Death, Australia, cat. no. 3303.0);
• adoptions, sex changes, legitimations and corrections;
• births to foreign diplomatic staff; and
• births occurring on Norfolk Island.

7 The scope for each reference year of the Birth Registrations collection include:

• births registered in the reference year and received by ABS in the reference year;
• births registered in the reference year and received by ABS in the first quarter of the subsequent year; and
• births registered in the years prior to the reference year but not received by ABS until the reference year or the first quarter of the subsequent year, provided that these records have not been included in any statistics from earlier periods.

8 Birth records received by ABS during the March quarter 2010 which were initially registered in 2009 (but not fully completed until 2010) were assigned to the 2009 reference year. Any registrations relating to 2009 which were received by ABS from April 2010 were assigned to the 2010 reference year.

9 Prior to 2007, the scope for the reference year of the Birth Registrations collection included:

• births registered in the reference year and received by ABS in the reference year;
• births registered in the reference year and received by ABS in the first quarter of the subsequent year; and
• births registered during the two years prior to the reference year but not received by ABS until the reference year.

Coverage of birth statistics

10 Ideally, for compiling annual time series, the number of events (births) should be recorded as all those occurring within a given reference period such as a calendar year. Due to lags in registration of births and the provision of that information to the ABS from state/territory Registrars of Births, Deaths and Marriages, data in this publication are presented on a year of registration basis.

11 In effect there are three dates attributable to each birth registration:

• the date of occurrence (of the birth);
• the date of registration or inclusion on the state/territory register; and
• the month and year in which the registered event is provided to the ABS.

12 Data in this publication are presented according to date of registration, unless otherwise stated. The registration date differs between states and territories, and should be taken into account when analysing birth statistics:

• for births registered in New South Wales, Victoria, Western Australia and the Australian Capital Territory, the birth registration date is the date at which the record is entered into the registration processing system;
• for births registered in South Australia, preliminary and final registration dates are allocated. Where a record requires further information a preliminary date is assigned. Once all data are finalised, a final registration date is assigned to the birth record which is provided to the ABS as the registration date;
• for births registered in Queensland, the registration date is the date at which all data on the birth record are finalised. This may be before the birth is entered into the registration system;
• for births registered in the Northern Territory, the registration date is the date at which the record is entered into the registration system. For birth records not received by the Registrar within 60 days of the birth, the Registrar will register the child as 'unnamed' and not finalised; and
• for births registered in Tasmania, a date is allocated when the birth record is entered into the registration system. The ABS receives an 'insertion' date which is the date when any information relating to the birth is entered into the registration system.

CLASSIFICATIONS

Nuptiality

13 Nuptiality relates to the registered marital status of the parent(s) of the child at the time of birth. Confinements and births are classified as:

• nuptial where the father registered was married to the mother at the time of the child's birth, or where the husband died during the mother's pregnancy. Confinements and births to Aboriginal and Torres Strait Islander mothers considered to be tribally married to the father of the child are classified as nuptial; and
• ex-nuptial where the parents were not in a registered marriage at the time of the child's birth, irrespective of whether the parents were living together at the time of the birth.

14 Ex-nuptial births and confinements are further classified as paternity acknowledged (where the father signed the birth registration form) or paternity not acknowledged (where the father did not sign the birth registration form).


Australian Standard Geographical Classification

15 The Australian Standard Geographical Classification (ASGC) is a hierarchical classification system consisting of six interrelated classification structures. The ASGC provides a common framework of statistical geography and thereby enables the production of statistics which are comparable and can be spatially integrated.

16 For further information refer to Australian Standard Geographical Classification (ASGC) (cat. no. 1216.0).


Standard Australian Classification of Countries

17 The Standard Australian Classification of Countries (SACC) (Second Edition) groups neighbouring countries into progressively broader geographical areas on the basis of their similarity in terms of social, cultural, economic and political characteristics.

18 For further information refer to Standard Australian Classification of Countries (SACC), Second Edition (cat. no. 1269.0).


DATA SOURCES

19 Registration of births is the responsibility of state and territory Registrars of Births, Deaths and Marriages and is based on data provided on an information form completed by the parent(s) of the child. This form is the basis of data provided to the ABS by the Registrars, for compilation into aggregate statistics in this publication. Most data items are collected in all states and territories and therefore statistics at the national level are available for most characteristics. Some states collect additional information.

20 Hospitals and birth clinics notify state and territory registries of recent births on a regular basis, except in Western Australia. For births where a notification has been received by a registry, but has not been registered within the prescribed time period, a reminder letter is sent to the parent(s) of the child.


State and territory data

21 As a result of an amendment made in 1992 to section 17(a) of the Acts Interpretation Act 1901-1973 (Cwlth), the Indian Ocean territories of Christmas Island and Cocos (Keeling) Islands have been included as part of geographic Australia, hence another category of the state and territory classification has been created. This category is known as 'Other Territories' and includes Christmas Island, the Cocos (Keeling) Islands and Jervis Bay Territory.

22 Prior to 1993, births to mothers usually resident in Christmas Island and Cocos (Keeling) Islands were included with Off-Shore Areas and Migratory in Western Australia, while births to mothers usually resident in Jervis Bay Territory were included with the Australian Capital Territory. In 2009, there were 23 births to mothers usually resident in Jervis Bay Territory, Christmas Island and the Cocos (Keeling) Islands.

23 Birth statistics for states and territories have been compiled and presented according to the state or territory of usual residence of the mother regardless of where in Australia the birth occurred and was registered, except where otherwise stated. In the following table, data are presented on a state or territory of registration basis. Births which took place outside Australia are excluded from the statistics. Births to mothers who were usual residents of Australia's Other Territories (Christmas Island, Cocos (Keeling) Islands and Jervis Bay Territory) are registered in other Australian states.

Sub-state/territory fertility rates

25 Age-specific and total fertility rates for sub-state/territory regions (for example, Statistical Divisions) presented in data cubes released with this publication are average rates for three years ending in the reference year. Rates for Australia and the states and territories in all other tables are based on single years of birth registration data.


DATA QUALITY

26 In compiling birth statistics, the ABS employs a variety of measures to improve the quality of the birth registrations collection. While every opportunity is taken to ensure that the highest quality of statistics are provided, the following are known issues associated with the statistics included in this publication.


Interval between occurrence and registration of births

27 For the most part, statistics in this publication refer to births registered during the calendar year shown. There is usually an interval between the occurrence and registration of a birth (referred to as a registration 'lag'), and as a result, some births occurring in one year are not registered until the following year or later. This can be caused by either a delay by the parent(s) in submitting a completed form to the registry, or a delay by the registry in processing the birth. Births which occur in November and December are also likely to be registered in the following year.

Births registered in 2009, Year of occurrence - Selected years
	2003 and earlier	2004	2005	2006	2007	2008	2009
State or territory of registration	%	%	%	%	%	%	%

Queensland	2.4	0.6	1.1	1.3	1.3	12.8	80.5

28 Of the 295,700 births registered in 2009, 88.1% occurred in 2009, while 9.1% occurred in 2008 and the remainder (2.7%) occurred in 2007 or earlier years.


Recent registration lags in Queensland

29 As a result of recent changes in the timeliness of registration of births in Queensland, care should be taken when interpreting changes in Queensland births between 2005 and 2009. In Queensland, 12.8% of the 65,900 births registered in 2009 occurred in 2008. A further 6.7% occurred in 2007 or earlier years. This lag is also evident in data for earlier years.

30 The December quarter 2009 also saw the Queensland Registry of Births, Deaths and Marriages devote significant time and resources to follow-up and finalise birth registrations where there was previously incomplete information. As part of the 'Retrospective Births Project' 1,780 births were registered, with approximately 40% registered as Aboriginal and Torres Strait Islander Australians (see paragraph 38 for more information). This project is now complete.

Tasmanian birth registrations

31 The Tasmanian Births, Deaths and Marriages Registration Act 1999 requires hospitals, doctors, midwives or other responsible persons to provide the Tasmanian Registrar with a list of babies born containing basic information such as date of birth and sex of the baby. In the case of a live birth, the birth notification must be provided within 21 days of the birth. These notifications have been provided to the ABS since 2002 and are also used in producing quarterly population estimates.

32 Under the Act, the birth of a child must also be registered by lodging a birth registration statement with the Registrar within 60 days after the date of birth of the child. Once the parent(s) submits the birth registration statement, the record is updated and the Registrar provides ABS with a complete registration record. Where a match between a birth notification and birth registration statement is identified, the record is quality assured to ensure completeness of the record.

33 Prior to 2007, records for which a birth registration form was not received were coded as 'ex-nuptial, paternity not acknowledged'. As a result, the number of ex-nuptial births in Tasmania may be overstated for 2002 to 2006. From 2007, these records have been excluded from all nuptiality statistics. In 2009, the number of unmatched birth registration forms was 167.


Indigenous births and fertility rates

34 The ABS Birth Registrations collection identifies a birth as being as Aboriginal and Torres Strait Islander (Indigenous) origin where at least one parent identifies themselves as being of Aboriginal, Torres Strait Islander or both origins on the birth registration form. Therefore, Aboriginal and Torres Strait Islander births may be attributed to either:

• Aboriginal and Torres Strait Islander mothers, including births where both the mother and father are Aboriginal and Torres Strait Islander Australians; or
• Aboriginal and Torres Strait Islander fathers and non-Indigenous mothers.

35 There are several data collection forms on which people are asked to state whether they are of Aboriginal and Torres Strait Islander origin. Due to a number of factors, the results are not always consistent. The likelihood that a person will identify, or be identified, as an Aboriginal and Torres Strait Islander Australian on a specific form is known as their propensity to identify. Propensity to identify can be thought of as the proportion of the total, unknown, number of Aboriginal and Torres Strait Islander people who identify as such on a specific form.

36 Propensity to identify as an Aboriginal and Torres Strait Islander Australian is determined by a range of factors, including how the information is collected; who completes the form; the perception of how the information will be used; education programs about identifying as an Aboriginal and Torres Strait Islander Australian; and cultural issues associated with identifying as an Aboriginal and Torres Strait Islander Australian.

37 Data presented in this publication may therefore underestimate the level of Aboriginal and Torres Strait Islander births and fertility in Australia. Lags in registrations may also affect reliability of measures of Aboriginal and Torres Strait Islander fertility. Caution should be exercised when interpreting Aboriginal and Torres Strait Islander Australians data presented in this publication, especially with regard to year-to-year changes.

Recent registration lags in Queensland

38 As described in paragraph 30, the Queensland Registry of Births, Deaths and Marriages undertook a 'Retrospective Births Project' during 2009 resulting in the registration of births where there was previously incomplete information. A significant proportion of these births were identified as Aboriginal and Torres Strait Islander Australians, which may affect fertility data in Queensland for 2009 (see Chapter 4: Effect of delayed birth registrations in Australia for further information).

39 Since 2006, Indigenous status of the mother and father for births registered in New South Wales has not been consistent with other jurisdictions. Specifically, where one parent is Indigenous (either Aboriginal and/or Torres Strait Islander), the other parent will be either 'Indigenous' or 'Not stated'. Further, where one parent is 'Non-Indigenous', the other parent will also be 'Non-Indigenous' or 'Not stated'. The Indigenous status of the child, where the birth is registered in New South Wales, is derived from the Indigenous status of each of the parents therefore there is a disproportionate number of records in New South Wales where the child's Indigenous status is 'Not stated'. Indigenous status of births registered in New South Wales should therefore be interpreted with caution. The ABS has been advised that this matter is being investigated as part of other processing system developments underway.

40 Chapter 3 reports on the number and characteristics of Aboriginal and Torres Strait Islander births and fertility rates in each state and territory, excluding the Australian Capital Territory and Other Territories. Aboriginal and Torres Strait Islander Australians data for the Australian Capital Territory and Other Territories are not analysed separately due to small numbers, but are included in totals for Australia.

41 The populations used to calculate Aboriginal and Torres Strait Islander fertility rates for 1996 to 2009 are experimental estimates and projections of the Australian Aboriginal and Torres Strait Islander female population aged 15-49 years, based on results of the 2006 Census of Population and Housing. For more information, see Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991 to 2021 (cat. no. 3238.0).

42 Estimates of annual numbers of Aboriginal and Torres Strait Islander births in Australia are available from two collections:

• ABS Birth Registrations: this publication is based on the registration of births with the Registrar of Births, Deaths and Marriages in each state and territory; and
• Australian Institute of Health and Welfare (AIHW) National Perinatal Statistics Unit perinatal statistics series: these data are primarily about babies born in hospitals and their mothers (see online Appendix: Differences Between Collections for more information).

43 In addition to these collections, it is possible to derive indirect estimates and projections of numbers of Aboriginal and Torres Strait Islander births, based on 2006 census-based Aboriginal and Torres Strait Islander population estimates:

• for 30 June 1991 to 30 June 2005, estimates of the Aboriginal and Torres Strait Islander population were derived from experimental Aboriginal and Torres Strait Islander resident population as at 30 June 2006 using a reverse survival technique based on experimental Aboriginal and Torres Strait Islander life tables (see Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991 to 2021, cat. no. 3238.0). Indirect estimates of Aboriginal and Torres Strait Islander births can then be derived using the number of Aboriginal and Torres Strait Islander children aged 0 at 30 June of each year; and
• for 30 June 2007 to 30 June 2021, projections of the Aboriginal and Torres Strait Islander population were derived from experimental Aboriginal and Torres Strait Islander resident population as at 30 June 2006 using assumptions on future levels of Aboriginal and Torres Strait Islander fertility, mortality and migration. Numbers of projected Aboriginal and Torres Strait Islander births were derived by applying assumed fertility rates to the Aboriginal and Torres Strait Islander female population aged 15-49 years at 30 June of each year (see Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991 to 2021, cat. no. 3238.0).

Edits and imputations

44 During edit processes for the Birth Registrations collection, some items are corrected where they conflict with other known information. Missing data for some data items are imputed when appropriate. In 2009, there were 258 birth registrations for which place of usual residence was imputed, and 34 registrations for which sex was imputed.


Parity (previous children of mother)

45 Parity refers to the number of (live) births that a woman has had. Birth order refers to whether a birth is the first, second, third or higher-order birth of the parent. In registering births, information is collected on the number of previous children born to a mother.

46 Changes in ABS processing of birth registrations from 2007 have resulted in the availability of improved information on previous births to mothers. Prior to 2007, ABS published information on previous births of the mother from the current relationship only, for all states and territories. From 2007 onwards, data on previous births for all relationships (both current and previous, if any) of the mother are collected for all states and territories, excluding Victoria and Queensland. Due to the high proportion of confinements in Tasmania in 2009 for which no information on previous children of the mother was available (table 2.7), data for Tasmania should be interpreted with caution. As a result of these inconsistencies, Australian figures are not available for publication.

47 These data are collected as a result of the increasing demand for parity data for analysis and dissemination. For more information on the use of parity data, and collection methods associated with these statistics, see Corr, P. and Kippen, R. 2006, The Case for Parity and Birth-Order Statistics, Australia and New Zealand Journal of Statistics, vol. 48, no. 2, pp. 171-200.

48 As a result of the above changes, data on previous births for 2007 onwards are not comparable with data for earlier years. However, the improved information indicates that the prevalence of first births (that is, mothers with no previous children) was overestimated prior to 2007, while numbers of mothers with two or more previous children were underestimated.

(b) Excluding Victoria, Queensland and Tasmania.
(c) Data for 2004 to 2006 are the number of previous births of the mother from the current relationship only. Data from 2007 onwards are previous births of the mother for all relationships.

Age of parent(s)

49 During birth registration processing since 2007, discrepancies have been identified between age of mother data as provided to the ABS and age of mother derived from date of birth of mother. In 2009 there were 17,133 records (6% of all confinements) for which the derived age of mother was found to be inconsistent with the reported age. For these records, the derived age of mother was used. The same process was applied to information on age of father, for which 16,466 records were affected. For years prior to 2007, median age may therefore have been overstated.


CONFIDENTIALITY

50 The Census and Statistics Act 1905 provides the authority for the ABS to collect statistical information, and requires that statistical output shall not be published or disseminated in a manner that is likely to enable the identification of a particular person or organisation. This requirement means that the ABS must take care and make assurances that any statistical information about individual respondents cannot be derived from published data.

51 Where necessary, tables in this publication have had small values suppressed or randomised to protect confidentiality. As a result, sums of components may not add exactly to totals.


ROUNDING

52 Calculations as shown in the commentary sections of this publication are based on unrounded figures. Calculations using rounded figures may differ from those published. Where figures have been rounded in tables, discrepancies may occur between sums of component items and totals.


ACKNOWLEDGEMENTS

53 ABS publications draw extensively on information provided freely by individuals, business, governments and other organisations. The efforts of Registries of Births, Deaths and Marriages to improve the data quality, coverage and timeliness of birth registration information, processes and systems are noted and valued by the ABS. Their continued cooperation is very much appreciated; without it, the wide range of statistics published by the ABS would not be available. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.
