History

The UK's system of official statistics has had a long history of incremental change and reform. Consequently it is hard to identify which particular point in history marked the 'birth' of today's system. Most commentators would agree that the foundations of the present institutional and governance arrangements for UK official statistics were laid in 1941 when the then Prime Minister, Winston Churchill, set up the Central Statistical Office (CSO) to aid the war effort.

Half a century later, the CSO was greatly enlarged when, in 1996, it merged with the Office of Population Censuses and Surveys (OPCS), itself created in 1970, to form the Office for National Statistics (ONS). One of the main aims of this merger was to encourage more integration between economic and social statistics across the UK.

A wider and decentralised UK statistical system, which continues to operate today was established in 1968 by Claus (now Lord) Moser, the then Director of the CSO. Claus Moser developed the concept of the Government Statistical Service (GSS) - a community of professionals and other civil servants across government responsible for the production of official statistics, and whose careers and work are co-ordinated from the centre - originally by the CSO and latterly by ONS.

The foundation for the legislation which became the Statistics and Registration Service Act 2007, and the setting up of the UK Statistics Authority, can be traced back to the 1990s, when calls were made from various quarters to create an independent statistics office.
