Understanding Society User Support

Hello,

Please see the user guide for the calendar year data, especially Section 2.2: "As the Calendar Year dataset is to be used for cross-sectional analysis, this relies on the inclusion of both year 1 and year 2 sample members (see section 3.1). Thus, the 2020 dataset consists largely of Wave 12 interviews with the year 1 sample and Wave 11 interviews with the year 2 sample. Therefore, any variables that are only collected in some of the waves included in this dataset are also excluded. As the files chmain (Wave 11 only) and parstyle (Wave 12 only) consist entirely of such variables these are excluded as well. The only exceptions to this rule are the wave specific
household identifiers and the politics and election variables." [https://understandingsociety.ac.uk/wp-content/uploads/documentation/user-guides/8988_calendar_year_user_guide_2020.pdf] Basically, this section explains that variables that are only asked in one of the waves covering the year of the Calendar Year dataset, in this case 2020, are not included in the dataset.

If you are interested in analysing these variables, please use the main survey dataset which includes data collected across all waves that are currently available 1-14, https://beta.ukdataservice.ac.uk/datacatalogue/studies/study?id=6614

If you have further questions please let us know.
