Integrated Census Microdata

Alternative Title: 
Also known as I-CeM

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 1911: England and Wales for 1851-1861, 1881-1911; Scotland for 1851-1901, making available to academic researchers the detailed information on parish-level about everyone resident in this country collected at each decennial census from 1851 to 1911 during a period of profound social change. 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.There is an interface to the data available at the UK Data Archive website: as well as that of the UK Data Service.                                                Details of other sources of Census data from the UK

File Descriptions: 

The I-CeM dataset is held at the UK Data Archive (UKDA) at the University of Essex in two forms - a ‘full’ version and an ‘anonymised’ version without names and addresses.


Anonymised data can be downloaded via the bespoke UKDA interface as delimited text. Alternatively, select cases and variables via the UKDA's Nesstar interface, and download in SAS, SPSS, or Stata formats.

Data Access: 

Data from the anonymised version can be downloaded by accredited researchers in higher education institutions via a bespoke download facility at the UKDA. This allows researchers to select and download subsets with maximum 500,000 cases. The data are also available via the NESSTAR interface, for basic analysis as well as download.

Data from the ‘full’ version can only be accessed within a secure data environment within the UKDA. Contact UKDA for permissions.
