Estimated Resident Population used to calculate per capita consumption figures were revised for 2011-12, 2012-13 and 2013-14 following the release of the 2016 census. This has caused minor revision of some per capita consumption figures. Some estimates for beer, spirits and RTDs for 2011-12, 2012-13 and 2013-14 have been revised in line with revisions to domestic data provided by the Australian Tax Office for (see paragraph 9 for information about the ATO's data provision). As cider estimates are calculated using total alcohol consumption, these estimates have also been revised in some cases. Revisions have caused only marginal differences in the data. The assumed proportion of total apparent alcohol used to calculate cider consumption for 2012-13 and 2013-14 were revised following the release of the 2014-15 National Health Survey (see paragraphs 34 to 45 for information about how cider is derived indirectly from Australian Bureau of Statistics National Health Surveys).
