QUALITY DECLARATION - SUMMARY
Every effort is made to minimise non-sampling error by careful design and testing of the collection instrument and the use of efficient operating procedures and systems. Non-sampling error also arises because information cannot be obtained from all persons selected in the survey.
Sampling error occurs because a sample, rather than the entire population, is surveyed. For further information regarding sampling and non-sampling errors, please refer to the Technical Notes.
There are no other data sources with which ABS data compiled from this survey can be directly compared. The Community preparedness for Emergencies, WA, 2011 survey is an ad hoc survey and is not part of the ongoing ABS program.
This survey topic was previously run as a State Supplementary Survey in 2007. Users are advised that there have been some changes to the data items collected across the two surveys (see Explanatory Notes 9 to 11 for details).
While the ABS seeks to maximise consistency and comparability over time by minimising changes to the survey, sound survey practice requires ongoing development to maintain the integrity of the data, its relevance to the changing needs of users and the efficiency of the collection.
Extreme caution should be used when comparing: statistics from two State Supplementary Surveys; or the Community preparedness for Emergencies, WA, 2011 survey with other related publications, as different methodologies may have been used.
The ABS has conducted several other surveys on preparedness for Emergencies. These include:
As the State Supplementary Survey is collected in tandem with the LFS, some changes to the LFS, for example modifications to the sampling method, may also impact on the State Supplementary Surveys. For a full list of changes made to the Labour Force Survey see Chapter 20 in Labour Statistics: Concepts, Sources and Methods (cat. no. 6102.0.55.001).
For other related publications please refer to the Related Publications section of the Explanatory Notes.
The Community preparedness for Emergencies, WA, 2011 survey collected information on whether or not households had taken specific steps to prepare for emergency events.
A major emergency refers to an event that threatens or damages the dwelling or threatens or harms occupants of the dwelling. Principal categories include bush fires, floods, earthquakes, cyclones and other hazardous events.
Data items were collected from Any Responsible Adult (ARA), on behalf of the household. The ABS makes every effort to ensure correct and consistent interpretation of question wording, and applies consistent processing methodologies.
