QUALITY DECLARATION - SUMMARY
The ABS aims to produce high quality data from its industry collections while minimising the reporting burden on businesses. To achieve this, extensive effort is put into collection and questionnaire design, collection procedures and processing. Estimates were produced using number raised estimation methodology with a sample of 939 production and post-production services businesses, and a census of 71 commercial free-to-air, subscription and public television broadcasters and subscription television channel content providers and 107 digital games developers. Note that the business counts published in this publication are not the same as the number of businesses surveyed due to businesses ceasing trading during the financial year or having been deemed as out of scope.
For this collection, non-sampling error may result from such things as deficiencies in reporting and/or errors made in compiling results. The extent to which non-sampling error affected the results of the collection is not precisely quantifiable. Every effort was made to minimise reporting error by careful design of questionnaires, intensive training of collection analysts and efficient data processing procedures. Additionally, to ensure the accuracy of the estimates produced, the data have been checked against previous collection results and other sources, including contact with providers.
There was an 81% live response rate from all production and post-production services businesses that were surveyed and found to be operating during the reference period. Data were imputed for the remaining 19% of operating businesses. Imputed responses contributed 6.2% to the estimate of total income.
The ABS has been conducting collections of film and video production and post-production businesses periodically since 1993–94, television broadcasters since 1996-97 and digital games developers since 2006-07. While the ABS seeks to maximise consistency and comparability over time by minimising changes to the collections, sound collection practice requires ongoing development to maintain the integrity of the data, a collection's relevance to the changing needs of users, and the efficiency of the collection. Additionally, given the irregular frequency of these collections, they are not primarily designed to monitor change over time.
Caution should be used when referencing historical data. Changes made to these collections over time include changes in scope, concepts, data item definitions and classifications. For a full list of changes made between the 2006-07 and the 2011-12 collections, refer to the Explanatory Notes of Film, Television and Digital Games Survey (cat. no. 8679.0).
The estimates from the Film, Television and Digital Games Survey are only available as original series and are not seasonally or trend adjusted. Although financial estimates in this publication relate to the full twelve months, employment estimates relate to the last pay period ending in June 2012, or the last pay period of the month specified. As such, estimates of values per person employed can be affected by any fluctuations in employment during the reference period. This is particularly relevant when assessing film and video production and post-production estimates owing to fluctuations in employment caused by the project-based nature of film and video production activities.
Further information on terminology and other technical aspects associated with statistics from the Film, Television and Digital Games Collection can be found in the publication Film, Television and Digital Games (cat. no. 8679.0), which contains detailed Explanatory Notes and Glossary.
