The UK censuses took place on 29th April 2001. They were run by the Northern Ireland Statistics & Research Agency (NISRA), General Register Office for Scotland (GROS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The Census 2001: Small Area Microdata SAM is a 5% sample of individuals for all countries of the UK, with 2.96 million cases. Local Authority is the lowest level of geography for England and Wales, Council Areas for Scotland and Parliamentary Constituencies for Northern Ireland. The Scilly Isles have been merged with Penwith and the City of London with Westminster. Orkney and Shetland are merged into one area. All other areas are identified. The median sample size for an authority is 5,600 records and nearly eighty authorities have more than 10,000 records. The amount of individual detail in the SAM is less than in the 2001 Individual Licenced Sample of Anonymised Records (I-SAR)(see under SNs 7205 and 7206) because of the greater geographical detail in the SAM.

Caveat - Students:
As with the Individual SAR, the SAM includes those enumerated in a communal establishment and also full-time students who were enumerated at an address that was not their usual term-time residence. For the latter there is only individual-level information on age, sex, marital status and full-time student status. It is recommended that these students are not included in any analyses as they do not form part of the usual residents population base.

This dataset contains 88 variables; a version designed for imputation analysis, which contains an extra 67 imputation flag variables, is available under SN 7208.

London's Metropolitan Police is by far the largest police force in the United Kingdom with 34,315 officers in 2024. At 16,356 officers, the Scottish police force has the second-largest force in terms of officer numbers, followed by Greater Manchester police force, which had 8,141 officers that year. Although the Metropolitan Police are responsible for policing most of Greater London, the City of London Police force covers the historic center of London, which is around one square mile in size, and numbered 995 officers in 2024. Crime in the UK In 2023/24 there were approximately 6.66 million crimes recorded by the police in England and Wales, compared with 6.74 million in 2022/23, which was the highest number of crimes recorded in a reporting year since 2002/03. Although crime declined from the mid-2000s to the mid-2010s, there has been a noticeable increase in crimes from 2014/15 onwards. In terms of the crime rate, England and Wales had the highest in the United Kingdom, at 89.7 offences per one thousand people, compared with 55 in Scotland, and 52.3 in Northern Ireland. Cuts to policing reversed in recent years Between 2010 and 2017, the number of police officers in the UK fell from 172,000 officers to just 150,000. During this same period, the London Metropolitan Police saw officer numbers decline by around 2,000 officers. The fall in police personnel was a result of UK-wide funding cuts, during this time period, with police expenditure falling from 19.3 billion in 2009/10 to 16.35 billion by 2013/14. This policy has since been reversed, with the last UK government recruiting officers and generally spending more on the police service. As of 2024, there were 170,500 police officers in the UK, and government expenditure on the police service was 27.3 billion British pounds.
