UK Statistical System

The UK statistical system is a group of decentralised government organisations across the UK, responsible for producing official statistics.

The governance of the UK statistical system is supported by the Statistics and Registration Service Act 2007.

The key components of the UK statistical system are:

  • UK Statistics Authority – the Board of the UK Statistics Authority is responsible for promoting and safeguarding the production of all UK official statistics to ensure they serve the public good.
  • Office for National Statistics (ONS) – ONS is the executive office of the UK Statistics Authority, doing its day to day work of producing official statistics. ONS is the largest producer of official statistics in the UK, and the UK’s National Statistical Institute (NSI).
  • UK government departments and the devolved administrations – each UK government department and devolved administration is responsible for producing and publishing statistics related to their area of expertise.
  • The Government Statistical Service (GSS) – The GSS is a community for all staff who work towards producing and publishing official statistics in England, Scotland and Wales. The GSS produces the vast majority of official statistics in the UK. Statistical staff in Northern Ireland maintain a close professional relationship with the GSS but are not formal members.
  • The National Statistician – The National Statistician is the government’s main adviser on statistical matters. The National Statistician is also the Head of the Government Statistical Service (GSS).

Many of the official statistics produced by the GSS are designated as National Statistics. Accreditation as National Statistics means that those statistics have been assessed as being compliant with the UK Code of Practice for Official Statistics, published by the UK Statistics Authority in January 2009.
