Understanding Society: Waves 1-14, 2009-2023: Special Licence Access, Census 2021 Lower Layer Super Output Areas

<span style="font-style: italic;">Understanding Society</span> (the UK Household Longitudinal Study), which began in 2009, is conducted by the Institute for Social and Economic Research (ISER) at the University of Essex, and the survey research organisations Verian Group (formerly Kantar Public) and NatCen. It builds on and incorporates, the British Household Panel Survey (BHPS), which began in 1991.
<p>This dataset contains Lower Layer Super Output Areas (LSOA) Census 2021-defined geographic variables for each wave of Understanding Society to date, and a household identification serial number for file matching to the main data. LSOA’s are provided for England and Wales households, Super Data Zones (SDZ) are provided for Northern Ireland and Data Zones (DZ), are provided for Scotland.</p>
<p>These data have more restrictive access conditions than those available under the standard End User Licence (see 'Access data' tab for more information).</p>
<p>These data are consistent with the ONS Postcode Directory (ONSPD). Please see the Geographical Lookup Tables document for further details.</p>
<p><b>Census 2001, 2011 and 2021 LSOA access restrictions</b></p>
<p>Census 2001 and 2011 - defined LSOA geographic variables are also available under Special Licence access conditions to match to Understanding Society data - see SN 6670 and SN 7248 respectively. When placing an order for these data users should note that, to minimise the risk of disclosure, users may access only one of SN 6670, SN 7248 or SN 9169 (this study).</p>
<p><b>Latest Edition Information</b></p>
<p>For the 3rd edition (April 2025) Scottish Data Zones (DZ) have been added.</p>
