For official statistics, Big Data open new opportunities: Statistical products may be delivered in shorter time, with more detailed breakdowns, at lesser costs, and with reduced response burden. However, a number of challenges are involved in using Big Data in official statistics: Solutions for methodological and technological issues are needed, a quality framework must be developed, and the staff has to get acquainted with new skills. Further issues concern the statistical environment such as legislative requirements, costs of sourcing of Big Data, and privacy, and have only indirectly to do with the statistical production. Finding solutions for these issues and developing standards that will be accepted internationally may require substantial efforts and take some time.
