The number of knife or sharp instrument offences recorded by the police in London rose to approximately 15,016 in 2023/24, compared with 12,786 in the previous year. This was the highest number of knife crime offences reported in London since 2019/20, when there were 15,928 offences. Between 2015/16 and 2019/20, knife crime in London increased yearly, with a particularly large increase occurring between 2016/16 and 2017/18. A wider trend The increase in knife crime witnessed in London has occurred alongside a general increase in overall crime throughout England and Wales. In 2022/23, there were approximately 6.74 million crime offences across England and Wales, compared with just over four million ten years earlier. During a similar time period, the number of knife homicides also increased, and reached 282 in 2021/22, compared with 186 in 2014/15. Due to strict gun laws in the United Kingdom, firearms are rarely used to commit homicides, with knives or other sharp instruments being used in over 41.4 percent of homicides in 2022/23. Acid and moped attacks While knife crime in London has certainly been given a lot of attention by the British media, the increase in acid and moped attacks during the same time period also generated many headlines. In 2017, for example, there were 471 acid attacks recorded by the Metropolitan Police, compared with just 51 in 2007. Moped crime also reached high levels in 2017, with both types of crime declining to much lower levels by the early 2020s. Although overall crime in London continued to rise until 2019/20, this fell back during the COVID-19 pandemic, but by 2023/24, the number of crimes committed in the capital had exceeded pre-pandemic levels.

The Great Britain Historical Database has been assembled as part of the ongoing Great Britain Historical GIS Project. The project aims to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain at sub-county scales. Further information about the project is available on A Vision of Britain webpages, where users can browse the database's documentation system online.

The Great Britain Historical GIS Project has also produced digitised boundary data, which can be obtained from the UK Data Service Census Support service. Further information is available at census.ukdataservice.ac.uk

Main Topics:

The Great Britain Historical Database is a large database of British nineteenth and twentieth-century statistics. Where practical the referencing of spatial units has been integrated, data for different dates have been assembled into single tables.

The Great Britain Historical Database currently contains :

• Statistics from the 1861 Census and the Registrar General's reports, 1851-1861
  
• Employment statistics from the census, 1841-1931
  
• Demographic statistics from the census, 1841-1931
  
• Mortality statistics from the Registrar General's reports, 1861-1920
  
• Marriage statistics from the Registrar General's reports, 1841-1870
  
• Trade union statistics for the Amalgamated Society of Engineers (ASE), 1851-1918
  
• Trade union statistics for the Amalgamated Society of Carpenters and Joiners (ASCJ), 1863-1912
  
• Official poor law statistics, 1859-1915 and 1919-1939
  
• Wage statistics, 1845-1906
  
• Hours of work statistics, 1900-1913
  
• Small debt statistics from county courts, 1847-1913 and 1938
  

There are eight tables in this part of the Great Britain Historical Database :

Plaw_c holds county-level data for England and Wales on numbers of paupers taken from the Annual Reports of the Poor Law Board and later the Local Government Board for 1st January and 1st July from January 1859 to January 1915, plus January 1919.

Plaw_c_f holds a full transcript of county-level pauperage statistics for England and Wales taken from the Annual Reports of the Poor Law Board and later the Local Government Board for 1st January and 1st July 1860, 1863, 1866, 1868 and 1879.

Plaw_u holds data taken from the Returns to Parliament made by the Poor Law Board, and later the Local Government Board listing number of paupers in each poor law union on the 1st January and 1st July. Coverage is as follows: all poor law unions in Lancashire for 1st January and 1st July from 1860 to 1871; all poor law unions in England and Wales for 1st January only from 1900 to 1912; all unions in London, Lancashire, Durham and selected major urban unions for 1st January and 1st July in 1875, 1879 and 1880.

Plaw_u_f contains a full transcript of poor law union-level pauperage statistics for selected unions taken from the Returns to Parliament. Coverage is as follows: all poor law unions in Lancashire for 1st January and 1st July from 1860 to 1871; all unions in Suffolk, Norfolk, Cambridgeshire, Lincolnshire, Nottinghamshire, Derbyshire, Cheshire and the East and West Ridings of Yorkshire for 1st January and 1st July in 1860, 1863, 1866, 1868 and 1869.

Plaw_iw holds inter-war poor law statistics taken from the Returns to Parliament for 1st January only for all poor law unions in England and Wales from 1922 to 1930, and for all counties and county-boroughs in England and Wales from 1931 to 1939.

Plaw_20 holds poor law statistics for England and Wales for 1920 and 1921 for selected poor law union for 1st January only.

Plu_gaz converts names of poor law unions as they appear in plaw_u, plaw_u_f, plaw_iw and plaw_20 into the form used in the GIS.

Plu_gis holds names and counties of poor law unions as they appear in the GIS; used for checking names and constructing plu_gaz.

Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

This dataset provides Census 2021 estimates that classify usual residents in households in England and Wales by disability, by general health, and by age. The estimates are as at Census Day, 21 March 2021.

Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands. Read more about this quality notice.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Lower tier local authorities

Lower tier local authorities provide a range of local services. There are 309 lower tier local authorities in England made up of 181 non-metropolitan districts, 59 unitary authorities, 36 metropolitan districts and 33 London boroughs (including City of London). In Wales there are 22 local authorities made up of 22 unitary authorities.

Coverage

Census 2021 statistics are published for the whole of England and Wales. However, you can choose to filter areas by:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Disability - Equality act disabled

People who assessed their day-to-day activities as limited by long-term physical or mental health conditions or illnesses are considered disabled. This definition of a disabled person meets the harmonised standard for measuring disability and is in line with the Equality Act (2010).

General health

A person's assessment of the general state of their health from very good to very bad. This assessment is not based on a person's health over any specified period of time.

Age (C)

A person’s age on Census Day, 21 March 2021 in England and Wales. Infants aged under 1 year are classified as 0 years of age.

This dataset provides Census 2021 estimates that classify usual residents aged 5 years and over in England and Wales by ethnic group, by provision of unpaid care, and by general health. The estimates are as at Census Day, 21 March 2021.

The ONS did not ask people aged under five years whether they provided unpaid care, so this variable counts usual residents aged five years and over. Read more about this quality notice.

Respondents could choose one out of 19 tick-box response categories, including write-in response options.

Unpaid care

An unpaid carer may look after, give help or support to anyone who has long-term physical or mental ill-health conditions, illness or problems related to old age.

This does not include any activities as part of paid employment.

This help can be within or outside of the carer's household.

General health
