Big Data, Official Statistics and Some Initiatives by the Australian Bureau ofStatistics

Official statisticians have been dealing with a diversity of data sources for decades. However, new sources of data in the Big Data domain provide an opportunity to deliver a more efficient and effective statistical service. This paper outlines a number of considerations for the official statistician when deciding whether to embrace a particular new data source in the regular production of official statistics. The principal considerations are relevance, business benefit, and the validity of using the source for official statistics in finite population inferences or analytic inferences. The paper also describes the Big Data Flagship Project of the Australian Bureau of Statistics (ABS), which has been established to provide the opportunity for the ABS to gain practical experience in assessing the business, statistical, technical, computational and other issues in using Big Data. In addition, ABS participation in national and international activities in this area will help it share experience and knowledge, while collaboration with academics will enable ABS to better acquire the capability to address business problems using the new sources of data as part of the solution.
