2011 Census Bulk Data Download (Release 2)
2011 Census Bulk data products are provided here in a bespoke CSV format designed to be automatically loaded into systems that allow users to interrogate and manipulate the data. They are not designed for use in desktop spreadsheet tools, and users seeking downloads that are designed for viewing in those tools are advised to use the standard tools on the main Nomis and NeSS websites.
Further information about the files can be found in the guidance document. Users of this data are encouraged to familiarise themselves with this guidance prior to use. Use the final table layouts document to view the variables available in each table.
Where possible and applicable the bulk data files contain values with more decimal points than are provided in equivalent tables on the ONS, Neighbourhood Statistics, and nomis websites. This affects area measurement and calculated fields. As a consequence, rounding of this data by users may result in figures that vary slightly from the data on these websites, as the latter may be expressed as whole numbers or rounded or truncated to fewer decimal points and different rounding methods may have been applied.
Statistical Disclosure Control
Two zip files are provided for each table: a ward file and an output area (OA) file. Both the ward and OA zip files also include data for local authorities, regions and countries.
