ABARE Survey on Indigenous People in Mining, Financial Year 2000/2001
Contents
I. Estimation, and Analysis
I1 Follow-up activities
What steps will be taken to ensure the expected response rate is achieved? (I1)
Note. Should detail what follow-up procedures are planned (such as, reminder letters, telephone follow-up of non-respondents, non-contacts, and refusals); and when and how many follow-ups will be attempted.
The survey procedure will involve:
- An initial telephone call to establish contact and to obtain e-mail addresses for survey despatch.
- Self-completion is the primary method of data collection, but a telephone interview conducted by an ABARE officer may be necessary to ensure responses are obtained.
- Follow-up telephone calls (and/or e-mails/faxes) will be progressed if contact is not established or there is non-response. We estimate there will be one reminder e-mail sent, and up to three follow-up telephone calls (if required). Mail will not be used, as many of these mine sites are in remote locations, and telephone calls (and/or e-mails/faxes) are more time efficient.
This method has been selected to ensure that our survey response rate is maximised.

I2 Outliers
Will outliers be identified, and, if so, how will they be handled? (I2)
Note. This item refers to the treatment of unusual or suspicious responses. It outlines treatment for responses which are found to be correct, and for responses which are found to be incorrect.
If the questionnaire information is correct then the data will be entered. If it is obvious that the questionnaire information is incorrect then the data will be amended before it is entered. Amendments will only be made after responses have been checked with respondents.

I3 Aggregation of data
Will data be aggregated into statistical tables, and if so what are the estimation formulae for the principal output data items?
(I3)
Note. Should include: how adjustments for outliers, imputation and frame undercoverage factors have been incorporated into estimation formulae; the variance formulae for variances that are to be published; and the weighting strategy.
Some aggregated statistics may be tabulated to provide information on indigenous employment at Australian mine sites. This is possible as the survey is a census.

I4 Non-sampling error
What allowances will be made for potential sources of non-sampling error in estimation? (I4)
Note. Should include: allowances to be made for non-response (such as imputation procedures, analysis of non-respondents); allowances to be made in estimation for frame deficiencies (eg. use of new business provisions); and other allowances to be made for other potential sources of non-sampling error in estimation.

I5 Analysis of results
What statistical data analysis techniques will be performed? (I5)
Note. Examples of statistical data analysis techniques include: significance testing, regression analysis, factor analysis and the like.
This survey process will only be a data collection exercise in order to obtain information on indigenous employment at Australian mine sites.

I6 Availability of results
How will the results of the survey be explained / presented to the major users? (I6)
Note. If applicable, should include: tables; analyses; unit record data; cautionary advice to assist users in interpreting the data (eg suppressing data due to high sampling variability, presenting data in the right context especially in cases of low response rates or low participation rates); and graphs.
For qualitative questions, responses will be summarised using histograms. For quantitative questions, responses will be summarised using graphs such as histograms, descriptive statistics, and economic indexes. Results may be analysed according to size of mine site, mineral resource, location, and other segmentations (as outlined in question B2). For the questions that require brief responses, results will be summarised. Aggregated results will be presented in an ABARE research report for DITR.
