Administrative data have been widely used to produce official statistics for many years; for some, such as death registrations, for more than 150 years. New technologies are now enabling the greater use of administrative data by users across all sectors. As well as providing new opportunities and benefits, the use of administrative data in official statistics by statistical producers brings with it a responsibility for ensuring that the data are sufficiently robust for these purposes. Equally, it is essential that any strengths and weaknesses are well understood and explained to users.
