The Integrated Census Microdata (I-CeM) project has produced a standardised, integrated dataset of most of the censuses of Great Britain for the period 1851 to 1921: England and Wales for 1851-1861, 1881-1921 and Scotland for 1851-1901 and 1921, making available to academic researchers, detailed information at parish level about everyone resident in Great Britain collected at most of the decennial censuses between 1851-1921. Users should note that the 1871 England and Wales census data and 1911 Scottish census data are not available via I-CeM.

The original digital data has been coded and standardised. In addition, the original text and numerical strings have always been preserved in separate variables, so that researchers can go back to the original transcription. However, users should note that name and address details for individuals are not currently included in the database; for reasons of commercial sensitivity, these are held under Special Licence access conditions under SN 7856 for data relating to England, Wales and Scotland, 1851-1911 and SN 9281 for data relating to England and Wales, 1921.

This study (7481) relates to the available anonymised data for 1851-1911, i.e. all available years except 1921. Data for England and Wales 1921 are available under SN 9280. The data are available via an online system at https://icem.ukdataservice.ac.uk/

Latest edition information

For the second edition (June 2024), the 1851-1911 data have been redeposited with amended and enhanced data values.

This dataset contains a variety of demographic measures (related to fertility, marriage, mortality and migration), plus a range of socio-economic indicators (related to households, age structure, and social class) for the 2000+ Registration Sub Districts (RSDs) in England and Wales for each census year between 1851 and 1911, and for the 600+ Registration Districts of Scotland 1851-1901. The measures have mainly been derived from the computerised individual level census enumerators' books (and household schedules for 1911) enhanced under the I-CeM project. I-CeM does not currently include data for England and Wales 1871, although the project has been able to access a version of the data for that year it does not contain information necessary to calculate many of the variables presented here. Scotland 1911 is also not available. Users should therefore beware that 1871 does not contain data for many of the variables. Additional data has been derived from the tables summarising numbers of births and deaths by year and areas, which were published by the Registrar General of England and Wales in his quarterly, annual and decennial reports of births, deaths and marriages. Data from the decennial reports was obtained from Woods (SN 3552) and we transcribed data from the quarterly and annual reports ourselves. Counts of births and deaths for Scottish Registration Districts were obtained from the Digitising Scotland project at the University of Edinburgh. The dataset builds on SN 8613 and SN 853547 which provide data for a more limited set of variables and for England and Wales only (the same dataset also has two UKDS SN numbers as it was re-routed by UKDS during the deposit process).

This project will present the first historic population geography of Great Britain during the late nineteenth century. This was a period of unprecedented demographic change, when both mortality and fertility started the dramatic secular declines of the first demographic transition. National trends are well established: mortality decline started in childhood and early adulthood, with infant mortality lagging behind, particularly in urban-industrial areas. The fall in fertility was led by the middle classes but quickly spread throughout society. Urban growth was fuelled by movement from the countryside to the city, but there was also considerable migration overseas, particularly from Scotland, although to some extent outmigration was offset by immigration. There was local and regional variation in these patterns, and a contrast between the demographic experiences of Scotland and of England and Wales. Marriage was later in Scotland but fertility within marriage higher, and the improvement in Scottish mortality was slower than that south of the border. However, while there has been research on local and regional patterns within each country, these have mainly been pursued separately, and it is therefore unclear whether there were real national differences or whether there were local demographic continuities across borders, and if so whether they followed economic, occupational, cultural or even linguistic lines. Understanding population processes involves a holistic appreciation of the interaction between the basic demographic components of fertility, mortality, nuptiality and migration, and how they come together, interacting with economic and cultural processes, to create a specific demographic system via the spread of people and ideas. This project is the first to consider a historical population geography of the whole of Great Britain across the first demographic transition, drawing together measures of nuptiality, fertility, mortality and migration for small geographic areas and unpacking how they interacted to produce the more readily available broad-brush national patterns for Scotland and for England and Wales.

We will build on our immensely successful project on the fertility of Victorian England and Wales, which used complete count census data for England and Wales to calculate more detailed fertility measures than ever previously possible for some 2000 small geographic areas and 8 social groups, allowing the investigation of intra-urban as well as urban-rural differences in fertility. The new measures allowed us to examine age patterns of fertility across the two countries for the first time. We were also able to calculate contextual variables from the census data which allowed us to undertake spatial analysis of the influences on fertility over time. As well as academic papers, our previous project presented summary data at a fine spatial resolution in an interactive online atlas, populationspast.org, a major new resource which is already being widely used as a teaching tool in both schools and universities.

In this new project we will calculate comparable measures of fertility and contextual variables using the full count census data for Scotland, 1851 to 1901 inclusive, to complement those for England and Wales....

The collection of data in these studies is part of a larger study on the decline of the Scottish cotton industry. The primary aim of the project was to answer questions regarding the causality and chronology of decline in the cotton industry. Since economic historians have viewed the decline of the Scottish cotton industry as a consequence of poor productivity it was decided to explore the relationship between capital and labour and in particular, the gender structure of the cotton mill.
To provide information on the occupational and age structure of the Scottish cotton industry in the years 1851, 1871 and 1891. Further, to distinguish the marital status of the female workers and to draw links between household structure and factory work.
Main Topics:

Names; addresses; age; sex; occupation; place of birth; relation to head of household, marital status.
There are three files in the dataset. These contain information on household structure with the details of each person in the household held as a separate record.

In 2023, the population of the United Kingdom reached 68.3 million, compared with 67.6 million in 2022. The UK population has more than doubled since 1871 when just under 31.5 million lived in the UK and has grown by around 8.2 million since the start of the twenty-first century. For most of the twentieth century, the UK population steadily increased, with two noticeable drops in population occurring during World War One (1914-1918) and in World War Two (1939-1945). Demographic trends in postwar Britain After World War Two, Britain and many other countries in the Western world experienced a 'baby boom,' with a postwar peak of 1.02 million live births in 1947. Although the number of births fell between 1948 and 1955, they increased again between the mid-1950s and mid-1960s, with more than one million people born in 1964. Since 1964, however, the UK birth rate has fallen from 18.8 births per 1,000 people to a low of just 10.2 in 2020. As a result, the UK population has gotten significantly older, with the country's median age increasing from 37.9 years in 2001 to 40.7 years in 2022. What are the most populated areas of the UK? The vast majority of people in the UK live in England, which had a population of 57.7 million people in 2023. By comparison, Scotland, Wales, and Northern Ireland had populations of 5.44 million, 3.13 million, and 1.9 million, respectively. Within England, South East England had the largest population, at over 9.38 million, followed by the UK's vast capital city of London, at 8.8 million. London is far larger than any other UK city in terms of urban agglomeration, with just four other cities; Manchester, Birmingham, Leeds, and Glasgow, boasting populations that exceed one million people.

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.

These data were originally collected by the Censuses of Population for England and Wales, and for Scotland. They were computerised by the Great Britain Historical GIS Project and its collaborators.

The census has gathered data on "occupations", meaning individuals' roles in the workplace, since the first household enumeration in 1841, and this collection includes most of the published results. However, how the results were classified varied greatly: for 1841, there is simply an alphabetical list of individual occupations, in 1851 the most basic classification was into workers in animal, vegetable and minerals, and so on. Further, the more detailed the occupational classification used, space considerations tended to require a less detailed geography; or, sometimes, the use of an abridged classification for small towns and rural areas; or even different tables and classifications for men and for women. There are consequently multiple datasets for some years.

Latest edition information

For the second edition (October 2022), the data and documentation have been revised.

This Special Licence access dataset contains names and addresses from the Integrated Census Microdata (I-CeM) dataset of the censuses of Great Britain for the period 1851 to 1911. These data are made available under Special Licence (SL) access conditions due to commercial sensitivity.

The anonymised main I-CeM database that complements these names and addresses is available under SN 7481. It comprises the Censuses of Great Britain for the period 1851-1911; data are available for England and Wales for 1851-1861 and 1881-1911 (1871 is not currently available for England and Wales) and for Scotland for 1851-1901 (1911 is not currently available for Scotland). The database contains over 180 million individual census records and was digitised and harmonised from the original census enumeration books. It details characteristics for all individuals resident in Great Britain at each of the included Censuses. The original digital data has been coded and standardised; the I-CeM database has consistent geography over time and standardised coding schemes for many census variables.

This dataset of names and addresses for individual census records is organised per country (England and Wales; Scotland) and per census year. Within each data file each census record contains first and last name, street address and an individual identification code (RecID) that allows linking with the corresponding anonymised I-CeM record. The data cannot be used for true linking of individual census records across census years for commercial genealogy purposes nor for any other commercial purposes. The SL arrangements are required to ensure that commercial sensitivity is protected. For information on making an application, see the Access section.

The data were updated in February 2020, with some files redeposited with longer field length limits. Users should note that some name and address fields are truncated due to the limits set by the LDS project that transcribed the original data. No more than 10,000 records out of some 210 million across the study should be affected. Examples include:

• England and Wales:
  • 1851 - truncated at the 24th character (maximum I-CeM field length 95 characters)
  • 1881 - truncated at the 16th character (maximum I-CeM field length 50 characters).
• Scotland: for 1851‐71, truncations affect less than 0.01% of all addresses and for 1851 around 1% at most
  • 1851 - truncated at the 70th character
  • 1861 - truncated at the 76th character
  • 1871 - truncated at the 82th character
  • 1881 - truncated at the 50th character.

This project aimed to extend knowledge of late nineteenth century Scottish, and hence British, demography, by producing four parallel longitudinal data sets by linking individuals in the decennial censuses of 1861-1901 with the births, deaths and marriages from civil registers for the lowland town of Kilmarnock, the Hebridean Island of Skye, and the rural parishes of Torthorwald and Rothiemay, places with contrasting economic and social structures and physical environments. The resulting data source is rich in information relating to the social, occupational, household, and demographic characteristics of individuals, who can also be situated within their physical environment. The relatively large scale of the data-sets allows greater accuracy and detail in the multivariate analysis of mortality, fertility, nuptiality and migration. Special permission was granted by the General Register Office, Edinburgh, for access to the civil registers of births, marriages and deaths, and these have been linked to the census entries for the same individuals, allowing the creation of full or partial life histories. Linkage has been carried out using a sets of related individuals approach in a relational data-base system using computer algorithms and hand-finishing (see Reid, Davies and Garrett (2006) 'Nineteenth century Scottish demography from linked censuses and civil registers: a sets of related individuals approach', History and Computing, 14(1+2), 2002 (publ. 2006), pp. 61-86).

The terms of our agreement with the General Register Office for Scotland do not allow us to deposit the births, marriages and deaths for archiving, which prevents deposit of the linked material. However we can deposit the census material annotated to include the years of birth, death and marriage of an individual (but no other details of these events). Two separate census deposits are being made. This is a version of the raw data, with no standardisation or enhancement apart from corrections or changes to ensure consistency, notes made by data entry personnel, and household and individual identifiers.



Main Topics:

The data consist of transcriptions of the census enumerators' books for Skye, Kilmarnock, Rothiemay and Torthorwald, for the years 1861, 1871, 1881, 1891 and 1901. The following information on all individuals within all households on census night is provided: address (three fields); forename(s), surname(s); relationship to head of household; marital status; age; sex; occupation; other occupational information such as employment status, where available; county or birth, parish of birth; language; and number of rooms in the household. The data collection also contains details of where each individual appears in the census returns by giving the name of the registration district, the number of the enumeration district, the schedule number as indicated on the census enumerators' books, and household and person identification codes created by the project. Some variables are not available for all years or places: see project documentation for more details.
