New for Census 2021 outputs, will be a safeguarded household file. set of variables for an anonymised random sample of 1% of households, down to regional level, in the Census 2021 output database. We are also excited to be contributing to the University of Minnesota’s Integrated Public-Use Microdata Series (IPUMS) project. This europe rcs data international project brings census microdata from over 100 countries together to form the world’s largest archive of census microdata.
How origin-destination and microdata will be made available
We need to balance protecting the confidentiality of personal information and ensuring data can be made available for detailed analysis. Public data will be made available to everyone in a combination of data visualisation products and data tables. We use safeguarded and secure environments to make the more detailed origin-destination data and microdata available. For Census 2021, we will place the most detailed data, classified as secure, in our Secure Research Service (SRS). This data will only be available to approved or accredited researchers. It is likely that the UK Data Service will continue to host, and manage access to, the safeguarded data under terms and conditions set by ONS. We are working to improve access to safeguarded data compared with 2011.
