Census 1981, Great Britain
The secure microdata files consist of random samples of 9% of people or households in the 1981 Census output database for Great Britain.
The 1981 Census microdata for Great Britain 9% Sample: Secure Access dataset was created from existing digital records from the 1981 Census.
The file was created under a project known as Enhancing and Enriching Historic Census Microdata Samples (EEHCM), which was funded by the Economic and Social Research Council with input from the Office for National Statistics (ONS) and National Records of Scotland.
The project ran from 2012 to 2014. It was led from the UK Data Archive, University of Essex, in collaboration with the Cathie Marsh Institute for Social Research (CMIST) at the University of Manchester and the Census offices.
All data hosted on the Integrated Data Service (IDS) are de-identified.
