description: &lt;p&gt;Understanding Society (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.&lt;/p&gt; The &lt;i&gt;Innovation Panel&lt;/i&gt; is conducted as part of &lt;i&gt;Understanding Society&lt;/i&gt;. It is designed for experimental and methodological research relevant to longitudinal surveys. As far as practical its design, content, and data collection procedures are similar to the main stage &lt;i&gt;Understanding Society&lt;/i&gt; survey, held at the UK Data Archive under SNs 6614 (End User Licence version), 6931 (Special Licence) and 6676 (Secure Access). It is a multi-topic household survey representative of the population of Great Britain. Data collection takes place annually mainly using computer assisted personal interviewing (CAPI). One person completes the household questionnaire. Each person aged 16 or older answers the individual adult interview and self-completion questionnaire. Young people aged 10 to 15 years are asked to respond to a paper self-completion questionnaire. The &lt;i&gt;Innovation Panel&lt;/i&gt; has multiple experimental studies in which households are randomly assigned to a particular instrument or survey procedure. Experiments can relate to survey procedures, questionnaire design, or substantive social science questions. The experiments are described in the User Manual and in &lt;a href="https://www.understandingsociety.ac.uk/research/publications/working-papers" title="Understanding Society Working Papers"&gt; Understanding Society Working Papers&lt;/a&gt;. Further information about the &lt;i&gt;Innovation Panel&lt;/i&gt; is also available on the main &lt;a href="https://www.understandingsociety.ac.uk/documentation/innovation-panel" title="Innovation Panel"&gt; Innovation Panel&lt;/a&gt; webpage.&lt;br&gt; &lt;br&gt; &lt;b&gt;Secure Access Dataset&lt;/b&gt;:&lt;br&gt; The &lt;i&gt;Understanding Society: Innovation Panel, Waves 1-11, 2008-2018: Secure Access, National Grid Reference (Easting, Northing, OSGRDIND)&lt;/i&gt; dataset contains British National Grid postcode grid references (at 1m resolution) for each household surveyed, derived from the ONS National Statistics Postcode Directories (NSPD). Grid references are presented in terms of Eastings and Northings, which are distances in metres (east and north, respectively) from the origin (0,0), which lies to the west of the Scilly Isles. Each grid reference is given a positional quality indicator to denote the accuracy of the grid reference. In the majority of cases, the assigned grid reference relates to the building of the matched address closest to the postcode mean. No grid references are provided for postcodes in the Channel Islands and the Isle of Man.&lt;br&gt; &lt;br&gt; The Secure Access version of &lt;i&gt;Understanding Society: Innovation Panel 2008-2018&lt;/i&gt; includes all files in the Special Licence version, plus files containing the 3 variables relating to the National Grid Reference for each household: Easting, Northing and positional quality indicator (OSGRDIND). All other files are the same as in the Special Licence version, which is held under SN 7083.&lt;br&gt; &lt;br&gt; &lt;b&gt;Related UK Data Archive studies&lt;/b&gt;:&lt;br&gt; The Secure Access version of the dataset has more restrictive access conditions than standard End User Licence or Special Licence access datasets (see 'Access' section below). Further details and links to the less restrictive versions can be found on the &lt;a href="http://discover.ukdataservice.ac.uk/series/?sn=2000053" title="Understanding Society series"&gt; Understanding Society series&lt;/a&gt; Key data page.&lt;br&gt; &lt;br&gt; For the seventh edition (June 2019), Wave 11 has been added with accompanying documentation, and Waves 1 to 10 redeposited with some data edits. See the documentation file '7332_ip_waves_1-10_changes_collated.pdf' for details of the changes.&lt;br&gt; &lt;br&gt;
