<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 Kantar Public and NatCen. It builds on and incorporates, the British Household Panel Survey (BHPS), which began in 1991. <p class="x_x_MsoNormal">This dataset contains Acorn geodemographic segmentation codes for each household in every wave of Understanding Society and harmonised BHPS, together with a household identification number (hidp) allowing it to be linked to the main Understanding Society data files. The dataset is produced by matching the Acorn segmentation against every Understanding Society household at the postcode level.</p> <p class="x_x_MsoNormal">The Acorn segmentation system itself is developed and maintained by CACI Ltd and is designed to identify characteristics of each postcode according to a hierarchical structure of 7 categories, 22 groups and 64 types. For details on the Acorn segmentation structure and how it is produced please refer to the documentation and the <a href="https://acorn.caci.co.uk/">CACI</a> website.</p> <p class="x_x_MsoNormal">These data have more restrictive access conditions than those available under the standard End User Licence (see 'Access' section). <br> <br> <b>Latest Edition Information</b><br> </p> <p>For the 13th edition (November 2023), data for Wave 13 have been added.</p> <p class="x_x_MsoNormal"><span></span></p> <span></span><span></span> <p></p>
