  • Quality Declaration - Summary



    Confidentialised Unit Record Files (CURFs) are released in accordance with the conditions specified in the Statistics Determination section of the Census and Statistics Act 1905 (CSA). This ensures that confidentiality is maintained whilst enabling micro level data to be released. More information on the confidentiality practices associated with CURFs can be found at the "How is CURF data confidentialised?" page.

    For information on the institutional environment of the Australian Bureau of Statistics (ABS), including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, please see ABS Institutional Environment.


    The Employee Earnings and Hours CURF is only available as an expanded CURF accessed via the RADL. The EEH survey produces estimates of the composition and distribution of employee earnings, the hours they are paid for, and the methods used to set their pay (i.e. award only, collective agreement, or individual arrangement).

    The CURF contains all data items available from the survey, with the exception of Industry and Level of Government. Some of the key data items on the CURF include:

    • Weekly earnings - Ordinary time, Overtime, Amounts salary sacrificed, and Total earnings (available as continuous variables)
    • Hours paid for - Ordinary time, Overtime, and Total hours paid for (available as continuous variables)
    • Methods of setting pay
    • Employee characteristics - e.g. Sex, Full-time/Part-time status, Managerial status, Occupation (available at the 1, 2 and 3 digit ANZSCO level)
    • Business characteristics - State, Sector and Employer unit size.

    For further details on the content of the CURF, please see the data items list.


    The reference period for the May 2006 Survey of Employee Earnings and Hours survey was the last pay period ending on or before 19 May 2006. Results from the survey were released on 20 April 2007 in the publication, Employee Earnings and Hours, Australia, May 2006 (cat. no. 6306.0). Development of the CURF commenced in mid-2008, following a feasibility study.


    The EEH CURF contains individual employee level data (unit records) while the EEH publication contains aggregate data. Along with unit record data, the CURF contains finer levels of detail for data items than what is otherwise published. For more information on the level of detail provided in the CURF please see the data items list.

    Steps to confidentialise the data made available on the CURF are taken in such a way as to maximise the usefulness of the content while maintaining the confidentiality of respondents to ABS statistical collections. As a result, it may not be possible to exactly reconcile all statistics produced from the CURF with previously published statistics. However, these differences are not significant and should not diminish the value of the CURF in analysis.

    The steps taken to preserve confidentiality include:
    • omitting two data items included in previously published output - Industry and Level of government
    • reducing the level of detail available for one data item - Employer unit size is only available on the CURF in three broad groups
    • perturbation of all earnings data items
    • modifying the weights for some records.

For information on the survey sample size and response rates see the Explanatory Notes in Employee Earnings and Hours, Australia, May 2006 (cat. no. 6306.0).
