These digital boundaries were created by the Great Britain Historical GIS Project and form part of the Great Britain Historical Database, which contains a wide range of geographically-located statistics, selected to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain, generally at sub-county scales.

They represent the boundaries of Registration Districts in England and Wales as in use at the date of each Census of Population between 1851 and 1911, 1911 being the last census to report extensively on these units.

These digital boundaries can be used to map economic, social and demographic statistics from the Censuses of Population, 1851 to 1911, the Registrar-General's reports from the same period, and other relevant statistical sources. They can also be used as reference maps for these administrative units.

Note that these Registration Districts were mostly identical to the Poor Law Unions which existed in the same period, but there are significant exceptions, most often where one Registration District was divided into multiple Poor Law Unions. These differences have been recorded by the Great Britain Historical GIS.

The boundary data contain the same numerical identifiers as are included in the GBHD transcriptions of census and vital registration statistics for Registration Districts, making statistical mapping straightforward.

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.

Further information about I-CeM can be found on the I-CeM Integrated Microdata Project webpages.

Details are available for each individual on place of enumeration, household and familial structure, age, gender, marital status, occupation, employment status, birthplace, disability, language spoken (in Wales and Scotland).

This dataset is designed to be used with the Integrated Census Micro-data (ICeM). It weights to adjust for the number of missing women in each Registration Sub-District (RSD) for every census year. More information is given in 'Weights to adjust for missing women in ICeM database 1851-1911 README' file.

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.

The 19th century censuses gathered data only on "occupations", meaning individuals' roles in the workplace, but the changing nature of work created a need for separate counts by "employer's business". The first such industry statistics resulted from the 1911 census, but the first data included here are from 1931. The 1931 data, unlike the later data, are tabulated by place of residence, as data on journeys to work were not gathered by that census.

Numbers of workers in each industry, usually cross-classified by gender. The industrial classifications used change substantially over time, and by modern standards generally go into great detail about the manufacturing sector. For 1931 and 1951, one set of tables provide a detailed classification for counties and large towns and another provides a simplified classification for small towns and rural districts.

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.

Abstract copyright UK Data Service and data collection copyright owner. This data collection uses Census returns to construct a consistent time series of population for urban centres in England and Wales 1801-1911. This allows the urban development and structure of England and Wales to be analysed, and provides a resource to other researchers seeking to make ready comparisons of other information with urban development across the nineteenth century. It has been derived from the work of three previous researchers: (1) Chris Law (1967) originally prepared it; (2) Brian Robson (1973) developed the data further and transcribed Law’s data and preserved it, and also added information on some smaller settlements for years before they became ‘urban’ under Law’s criteria; (3) Jack Langton (2000) undertook a different study for the 17th century to 1841 using the same basic methods and definitions as Law-Robson for 1801 and 1841 and corrected various errors and omissions in the Law-Robson material; he also disaggregated the Law-Robson data for the period to 1841 to reflect the fact that many places had not coalesced into large towns by this date. The database here combines these three sources. It was prepared by Bob Bennett (2011) for a study of local economies and chamber of commerce business representation.

This dataset contains a variety of measures of fertility, marriage and infant and child mortality, and also a range of socio-economic indicators (related to households, age structure, and social class) for the 2000+ Registration Sub Districts (RSDs) in both England and Wales, for each census year between 1851 and 1911. The measures have mainly been derived from the computerised individual level census enumerators' books (and household schedules for 1911) for England and Wales enhanced under the I-CeM project. I-CeM does not currently include data for 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. Users should therefore beware that 1871 does not contain data for many of the variables. Additional data, for some indicators, has been derived from the tables summarising numbers of births and deaths by year and areas, which were published by the Registrar General in his quarterly, annual and decennial reports of births, deaths and marriages.

Main Topics:

Fertility, Infant mortality, Child mortality, Nuptiality, Illegitimacy, Household indicators, Socio-economic status, Age-structure.

This data was originally published in the reports of the Registrar-General for England and Wales. It was computerised by the Great Britain Historical GIS Project and its collaborators. It forms part of the Great Britain Historical Database, which contains a wide range of geographically-located statistics, selected to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain, generally at sub-county scales.

In this period, 1911 to 1973, the main reporting units were over 1,500 local government districts, as compared to c. 600 Registration Districts pre-1911. As a result, most tabulations provide data only for the larger urban units, plus aggregates covering all Rural Districts and all other urban units in each county. This study centers on the main exception to this, an annual table providing counts of all births, all deaths and all infant deaths in all districts, appearing in the Registrar-General's Annual Reports from 1911 to 1920, then in the RG's Statistical Reviews from 1921 to 1973. Later reports include additional variables. This study also includes more limited transcriptions of causes of death and age-specific mortality.

The main annual table for local government districts 1911-73 provides an estimate of total population and counts of births and deaths for all years. Pre-1973, births are categorised by legitimacy as well as sex. Infant deaths under 1 year are counted for all years, stillbirths and deaths under 4 weeks from 1949, and deaths under 1 week from 1958. Various rates are also computed. Slightly different data were reported during World War 2.

The table of annual age-specific causes of death holds data for census years only, 1921 to 1971,for, typically, "London and Metropolitan Boroughs, County Boroughs, Aggregates of other Urban and of Rural Districts in each Administrative County", for varying numbers of causes of death (1921 = 33, 1961 = 64, 1971 = 7) and, generally, ten-year age bands.

The other two tables provide more information on causes of death and age at death, but only for the 1910s and 1920s (Graham Mooney contributed to the table of causes of death 1911-20).

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 British Business Census of Entrepreneurs, 1851-1911 (BBCE) is a quality-controlled, consistent, and integrated database that is as complete as feasible for all British business proprietors in the period 1851-1911, and aligned to modern definitions used up to the 2011 census. It covers England and Wales for 1851-1911, and Scotland for 1851-1901. It includes as fully as possible all: Employers (those who employed others); Sole proprietor own account self-employed (those who employed no-one else); and Directors of corporations (Limited Companies). BBCE mainly derives from the Integrated Census Microdata (I-CeM) Project (see SN 7856), to which BBCE is linked via individual RecID; but BBCE also infills missing or truncated data in I-CeM using census transcripts from S&N and coding from CEBs, and also provides entrepreneur data for 1871. BBCE makes available employment status codes for all years 1851-1911, occupational coding to main occupation and portfolios, coding of partnerships and directors, and extracts workforce size where given by employers over 1851-81, and for farmers the acreage occupied. There is data linkage and coding of individuals identifiable in the census who were directors of corporations, together with information on their companies.

This study mainly comprises data from the RG's Annual Reports, with some data from the Quarterly Returns. A very extensive transcription from the Decennial Supplements forms a separate study.

Latest edition information

For the second edition (December 2022) the previous data and documentation files were replaced with new versions, and access conditions were changed from safeguarded to open access.

Annual counts of births and deaths for all Registration Districts in all years 1850 to 1910, with marriages for some years.

Annual cause-of-death data for all Registration Districts in all years, 1856 to 1910. The causes of death focus on epidemic diseases.

Annual age-specific mortality data for all Registration Districts for 1840-42, 1850-52, 1860-1882, 1890-92, 1900-02, 1908-1910 (i.e. for most of the period, census years plus immediately adjacent years).

Quarterly counts of births, deaths and selected causes of death from the Registrar-General's Quarterly Returns, for Registration sub-Districts. This is limited to (1) a full transcription of all four quarters for each census year within the period covered by the Quarterly Returns: 1871, 1881, 1891, 1901 and 1911; (2) numbers of births and infant deaths in all sub-districts in the County of London from the full run of reports from 1871 to 1911; and (3) a full transcription of all four quarters of 1876, but limited to the north-west of England, defined as Cheshire, Lancashire and Westmorland plus Chapel-en-le-Frith and Hayfield Registration Districts in Derbyshire and Saddleworth in the West Riding.

Individual cholera deaths in London in summer and autumn 1866 arranged by date and causes of death, plus a variant which is adjusted for deaths in hospitals (these data were created by Graham Mooney).

A separate UKDS study contains decennial age-specific cause of death data for all Registration Districts in all decades from 1851-60 to 1901-10.

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

This aggregate-level dataset links poor relief data recorded on 1 January 1891 with several variables from corresponding 1891 census data, all at the level of the registration district (RD). Specifically, the numbers of men and women receiving indoor and outdoor relief in the ‘non-able-bodied’ category (taken as a proxy of the numbers of older-age men and women on relief) are accompanied with a series of socio-economic variables calculated from census data on the population aged 60 years and over (our definition of ‘old age’).

Thus, the dataset fulfils two objectives:

1. To start reconciling poor relief data from the House of Commons Parliamentary Papers archive with transcribed Integrated Census Microdata (I-CeM) available at the UK Data Service (UKDS).

2. To capture geographical variations in the proportion of older-age men and women on poor relief as well as in several household, occupational and migratory compositions recorded in the census, consulting data from 1891 as a pilot study in anticipation of an extended project covering all censuses from 1851-1911.

   The study of old age in history has generally had a narrow focus on welfare needs. Specific studies of the extreme poverty, or pauperism, of older people in late nineteenth-century London by Victorian contemporary Charles Booth (1840-1916) have remained remarkably influential for historical research on old age (Booth, 1894; Boyer and Schmidle, 2009). Old age is also examined through institutional care, particularly workhouse accommodation (Lievers, 2009; Ritch, 2014), while the subgroup of the elderly population that were not poor has been underexplored. However, my PhD thesis shows that pauperism was not a universal experience of old age between 1851 and 1911. Using transcribed census data for five selected counties in England and Wales, I find that pauperism was contingent upon many socio-economic factors recorded in census datasets, such as the occupational structure of older people, their living arrangements and their capacity to voluntarily retire from work based on their savings, land and capital. I find that, in some districts of the northern counties of Cheshire and the Yorkshire West Riding, the proportion of men described in the census as 'retired' and the proportion of women 'living on their own means' was greater than the respective proportions of men and women on welfare. For elderly men in particular, there were regional differences in agrarian work, where those in northern England are more likely to run smallholding 'family farms' whereas, in southern England, elderly men generally participate as agricultural labourers. I find that these differences play an important part in the likelihood of becoming pauperised, and adds to the idea of a north-south divide in old age pauperism (King, 2000). Furthermore, pauperism was predicated on the events and circumstances of people throughout their life histories and approaching their old age.

My fellowship will enable me to expand upon these findings through limited additional research that stresses an examination of the experiences of all older people in England and Wales. Old age has to be assessed more widely in relation to regional and geographical characteristics. In this way, we refine Booth's London-centric focus on the relationship between poverty and old age. My fellowship will achieve these objectives by systematically tracing the diversity of old age experiences. A pilot study will link welfare data recorded on 1 January 1891 from the House of Commons Parliamentary Papers archive with the socio-economic indicators contained in the 1891 census conducted on 5 April, all incorporated at the level of c. 650 registration districts in England and Wales. I will also visit record offices to extract data on the names of older people recorded as receiving welfare in materials related to the New Poor Law, thereby expanding on the PhD's examination of the life histories of older people.

With the key findings from my PhD presented above, I will spend my time addressing a wider audience on my research. As I will argue in blogs and webinars addressed to Age UK, the International Longevity Centre UK and History and Policy, a monolithic narrative of old age as associated with welfare dependency and gradual decline has been constructed since Booth's research in the late nineteenth century. This narrative has remained fixed through the growth of our ageing population, and the development of both old age pensions and the modern welfare state. My research alternatively uses historical censuses that reveal the economic productivity of older people in a manner that is not satisfactorily captured in present day discourse. I will also receive training on how to address my PhD to local schools, through the presentation of maps that present variations in the proportions of older people receiving welfare, and in the application of transcribed census data.

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.

Like England and Wales, the Scottish census gathered data on numbers of rooms (specifically, rooms with windows) from 1891 onwards, but the reports for 1891 and 1901 tabulate only the total number of rooms for each reporting area, so it is impossible to calculate numbers living in overcrowded conditions. This study comprises extensive although not always complete transcriptions of the housing density (persons per room) tables from the Scottish censuses of 1911, 1931, 1951, 1961 and 1971, cross-tabulating numbers of persons versus numbers of rooms. The 1921 reports do include similar data for Scottish counties, but these have not been computerised.

Housing Statistics (persons per room) from the 1911, 1931, 1951, 1961 and 1971 Censuses of Population.

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 a range of demographic and socio-economic variables for Registration Sub-Districts (RSDs) in England and Wales, 1851-1911. The measures have mainly been derived from the computerised individual level census enumerators' books (and household schedules for 1911) for England and Wales enhanced under the I-CeM project. I-CeM does not currently include data for 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. Users should therefore beware that 1871 does not contain data for many of the variables. Additional data, for some indicators, has been derived from the tables summarising numbers of births and deaths by year and areas, which were published by the Registrar General in his quarterly, annual and decennial reports of births, deaths and marriages. More information on the data, including overviews of the geographical patterns and changes over time, can be found on the Populations Past – Atlas of Victorian and Edwardian Population website, which provides an interactive mapping facility for these data.

The second half of the nineteenth century was a period of major change in the dynamics of the British population. This was a time of transformation from a relatively 'high pressure' demographic regime characterised by medium to high birth and death rates towards a 'low pressure' regime of low birth and death rates, a transformation known as the 'demographic transition'. This transition was not uniform across England and Wales: certain places and social groups appear to have led the declines while others lagged behind. Exploring these geographical patterns can provide insights into the process of change and the influence of economic and geographical factors. This project aimed to utilise the individual-level data of the Integrated Census Microdata (I-CeM) project to calculate age-specific fertility rates both for a range of fine geographical units covering England and Wales and for occupational groups and then to investigate the relationships between these rates and other socioeconomic variables. This was to provide, for the first time, widespread information of the age patterns of fertility which render insight into ‘starting’, ‘spacing’ or ‘stopping’ fertility regulating behaviour. A time series of such measures across geographical and social space is also vital when trying to identify how new forms of behaviour spread through the population. This database contains a variety of measures of fertility, marriage and infant and child mortality, and also a range of socio-economic indicators (related to households, age structure, and social class) for the 2000+ Registration Sub Districts (RSDs) in both England and Wales, for each census year between 1851 and 1871. Most of these data can be mapped using our interactive website www.populationspast.org.

This dataset contains the RecID for each individual who was a worker 1851-1911 in England and Wales census, for 1851-81 according to the NUM reconstruction process and their I-CeM occupation code (occode) cleaned and changed as part of the BBCE creation process.
