Who we are

The Office for National Statistics (ONS) is the executive office of the UK Statistics Authority (UKSA). Led by the National Statistician, Sir Ian Diamond, it is the UK’s national statistical institute and largest producer of official statistics. The ONS produces data, statistics and analysis on a range of key economic, social and demographic topics whilst leading the way on the international stage.

Key services include:

  • Measuring changes in the value and composition of the UK economy
  • Estimating the size, geographical distribution and characteristics of the population (including information from the Census)
  • Providing analysis on and indicators of other social and economic topics of national interest

The National Statistician also leads the following cross-government networks:

  • the Analysis Function – consists of around 17,000 people involved in the generation and dissemination of analysis across government and beyond. The function aims to improve the analytical capability of the Civil Service.
  • the Government Statistical Service (GSS) – is spread across a range of public bodies, including components of the devolved administrations.

The ONS sits at the heart of the GSS and Analysis Function and works with the network to provide the statistical evidence base, professional advice and analysis required by decision-makers to ensure policy and operations are evidenced and deliver value for money.

The ONS’s outputs, in line with the rest of the GSS, are regulated by the Office for Statistics Regulation (OSR). The OSR sets the code of practice; ensures that statistics are produced and disseminated in the public good; and enhances public confidence in the trustworthiness, quality and value of statistics. Those that meet the highest standards are given National Statistics status by the OSR – this applies to a range of the ONS’s key outputs.
