CALCULATING PRELIMINARY ERP
8.9 Some level of geographic grouping was considered necessary because of the high sampling error for some states/territories.
8.10 The geographic level to which the preliminary 2006 PES results were disaggregated for ERP purposes was determined after consideration of the sampling error and possible bias resulting from the groupings. The relative standard error (RSE) of the estimates of the Indigenous population in the five jurisdictional groups ranged from 3.5% for the Northern Territory to 7.3% for Western Australia. The RSE for Australia (excluding Other Territories) was 2.6%.
