AEC - Australian Electoral Commission
Age - Age is calculated as at 24 August 2017 using the date of birth on the Commonwealth Electoral Roll.
AMLPS - Australian Marriage Law Postal Survey
Direction - The Census and Statistics (Statistical Information) Direction 2017 issued by the Treasurer on 9 August 2017.
Eligible participants - Eligible participants are those enrolled on the Commonwealth Electoral Roll, or those who made a legitimate application for enrolment, by midnight on 24 August 2017 and were eligible to vote in a federal election as at 24 August 2017.
External Observers - Suitable people nominated by two parliamentary committees that reviewed and provided assurance to the mark recognition process conducted during survey processing.
Gender - The gender of eligible participants was taken from the Commonwealth Electoral Roll as at 24 August 2017.
Not further defined - Not further defined is used for records that do not fit in the other categories. This includes (but is not limited to) silent electors and Defence Force personnel deployed overseas whose age and gender were not provided to the ABS.
Participation - Participating in the survey means returning a survey response on a paper form, the online form or on the telephone. In some cases the response was unclear and therefore did not contribute to the yes/no outcome.
Response - The responses were 'Yes' or 'No' as well as 'Response not clear' where the intended response was not able to be determined.
Response clear - A clear response is recorded where the markings on the form can be clearly identified as indicating yes or no to the survey question.
Response not clear - Responses where there is not a clear 'Yes' or 'No' recorded. This includes (but is not limited to) forms where both boxes have been ticked, where there are no marks on the form (blank response) or where the question has been changed to make the answer unclear.
SAC - Secure Access Code - Used for online and phone survey participation. These codes were allocated by an automated process through requests on the Online Enquiry Form or by contact centre staff.
Silent Electors - Electors who have their address suppressed on the electoral roll.
State/Territory - The state and territory totals in the Australia Marriage Law Postal Survey are derived from the total number of responses/eligible electors within each Federal Electoral Division assigned to that state or territory. Federal Electoral Divisions do not cross State and Territory borders. Note that Jervis Bay Territory is included in the Australian Capital Territory Division of Fenner, the Territory of Norfolk Island is included in the Australian Capital Territory Division of Canberra and the Territories of Christmas Island and Cocos (Keeling) Islands are included in the Northern Territory Division of Lingiari.
Trusted Person - If a person could not access their survey form, or complete their survey form independently, they could authorise another person they trust to assist them with the survey, or to complete the survey form on their behalf. A person could not self-declare themselves to be a trusted person for someone else.
