TECHNICAL NOTE ESTIMATION METHODOLOGY
4 For the purpose of compiling the estimates in this publication, data for businesses as recorded on the ABS Business Register (ABSBR) contribute via one of three categories (or 'streams') in accordance with significance and collection-related characteristics.
COMPLETELY ENUMERATED (CE) STREAM
5 The CE stream consists of directly collected survey data for those units recorded on the ABSBR as having employment greater than 300, plus additional economically significant units in the Profiled Population and units significant to small state estimates.
GENERALISED REGRESSION ESTIMATION STREAM
6 The generalised regression estimation stream comprises directly collected data for those sampled units which are not in the CE stream and have turnover, in aggregate, above the bottom 2.5 percentile of BAS sales for that industry, or are identified as employing businesses (based on ATO information).
BUSINESS ACTIVITY STATEMENT (BAS) STREAM
7 The BAS stream comprises data for those non-employing businesses in the Non-Profiled Population whose turnover, in aggregate, is below the bottom 2.5 percentile of BAS sales for that ANZSIC subdivision.
8 Estimates for each of the selected industries were produced by aggregating the contributing data streams.
STATE AND TERRITORY ESTIMATES
9 State estimates were produced using both BAS data and survey data.
