Abstract copyright UK Data Service and data collection copyright owner.

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 and Scotland for 1851-1901, making available to academic researchers, detailed information at parish level about everyone resident in Great Britain collected at most of the decennial censuses between 1851-1911 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. 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.

Users should note that 1871 England and Wales Census data and 1911 Scottish Census data are not included in I-CeM.

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