The Bureau reviewed the use of secondary and mixed sources for official statistics in June 2010. The review concluded that it would be useful to share information and develop guidelines in this area. The ability to use various data sources effectively is increasingly important for the efficiency of statistical production. The Bureau asked the secretariat to create a knowledge base comprising the existing information on the topic.
Outcome of the review
The secretariat created and maintains a knowledge base called the ASSIST (Administrative and Secondary Sources in Statistics) wiki that contains links to relevant training materials, papers, conferences and publications, and circulated to the Bureau the publication Using administrative and secondary sources for official statistics.
In June 2011, the Conference suggested that a possible group on data collection, proposed in the first CES 2011 seminar, could deal with the topic of using secondary and mixed sources. In November 2011, the Bureau approved the organisation of a seminar on New frontiers for statistical data collection, which was held in 2012. In connection with the seminar, the secretariat carried out a survey of organization of data collection in statistical offices, and after the meeting a wiki for sharing resources and experiences in statistical data collection was set up. Following the success of this first seminar, a second seminar was held in September 2013, with a focus on mixed mode data collection, and the use of Big Data for official statistics.
The in-depth review paper was forwarded to the UNSC Friends of the Chair group on integrated economic statistics for consideration when preparing the guidelines on using secondary sources in economic statistics, and has been referred to on their website.
The topic of Big Data is the subject of an in-depth review by the CES Bureau in October 2013, and was identified as a priority for international collaboration activities in the area of the modernisation of statistical production and services, by the CES in 2013.
