The Statistics and Registration Service Act 2007 introduced the concept of Official Statistics. This encompassed National Statistics which are now described as Accredited Official Statistics by the Office for Statistics Regulation. The Official Statistics Order 2023 designated Jisc as a producer of Official Statistics following its acquisition of HESA..

The Code of Practice for Statistics (Principle T3: Orderly release) states that organisations should commit to releasing their statistics in an open and transparent manner that promotes public confidence.

This statement explains how Jisc complies with the principle.

Types of Official Statistics

Jisc publishes four types of official statistics as defined by the Code of Practice for Statistics:

  • Official statistics: Statistics produced by crown bodies, those acting on behalf of crown bodies, or those specified in statutory orders, as defined in section 6 of the Statistics and Registration Service Act 2007.
  • Official Statistics in Development: A subset of newly developed or innovative official statistics undergoing evaluation. Official Statistics in Development are published in order to involve users and stakeholders in the assessment of their suitability and quality at an early stage. Previously known as Experimental Official Statistics.
  • Ad-hoc official statistics:  Statistical analyses produced and released where there is a pressing need for official statistics in the public interest. 
  • Accredited Official Statistics: Official statistics accredited as fully compliant with the Code of Practice for Statistics. This accreditation is given by the Office for Statistics Regulation, in line with the Statistics and Registration Service Act 2007. Previously known as National Statistics.

Accredited Official Statistics can be broadly interpreted to mean that the statistics:

  • Meet identified user needs
  • Are well explained and readily accessible
  • Are produced according to sound methods
  • Are managed impartially and objectively in the public interest.

Once statistics have been accredited it is a statutory requirement that the Code of Practice shall continue to be observed.

Types of releases

Jisc releases Official Statistics in three types of publication:

  • Statistical Bulletins: provide high level statistics at a national level.
  • Open data releases: larger suites of open data tables providing detailed views of the data.
  • Ad-hoc Statistical Bulletins: statistical analyses published where there is a pressing need for official statistics in the public interest
