TECHNICAL NOTE 1 METHODOLOGY
3 For the purpose of compiling the estimates in this publication, data for businesses/organisations as recorded on the ABSBR contribute via one of two categories (or 'streams') in accordance with significance and collection-related characteristics.
COMPLETELY ENUMERATED STREAM
4 The completely enumerated stream consisted of directly collected survey data for those units recorded on the ABSBR as having employment greater than 300, plus additional 'significant' units in the ABSMP and units significant to small state estimates.
GENERALISED REGRESSION ESTIMATION STREAM
5 The generalised regression estimation stream comprised directly collected data for those sampled units which are not in the completely enumerated stream and have turnover, in aggregate, above a certain percentile of BAS sales for that industry. The percentile thresholds for each industry were as follows: 8601 (0.77%), 8609 (1.36%), 8710 (2.49%), and 8790 (1.73%).
STATE/TERRITORY AND REGION ESTIMATES
6 State and region estimation for this publication occurred through a combination of directly collected data and proration. All businesses/organisations were asked to provide key data by capital city/suburb and other areas. In addition, businesses/organisations which undertake multi-state operations received a more detailed survey form and asked to supply key details of their operations by state and territory. These key data items were then used to prorate estimates for other data items by state/territory and region. The remaining units, including government organisations, were treated as single state operations, and all data published against the state of head office.
