&lt;p class="x_MsoNormal"&gt;&lt;span&gt;The &lt;i&gt;Understanding Society COVID-19 Study, 2020-2021&lt;/i&gt; is a regular survey of households in the UK. The aim of the study is to enable research on the socio-economic and health consequences of the COVID-19 pandemic, in the short and long term. &lt;/span&gt;&lt;span&gt;The surveys started in April 2020 and took place monthly until July 2020. From September 2020 they took place every other month until March 2021 and the final wave was fielded in September 2021. They complement the annual interviews of the &lt;i&gt;Understanding Society&lt;/i&gt; study. The data can be linked to data on the same individuals from previous waves of the annual interviews (&lt;/span&gt;&lt;a href="https://beta.ukdataservice.ac.uk/datacatalogue/studies/study?id=6614" target="_blank"&gt;&lt;span&gt;SN 6614&lt;/span&gt;&lt;/a&gt;&lt;span&gt;) using the personal identifier pidp. However, the most recent pre-pandemic (2019) annual interviews for all respondents who have taken part in the COVID-19 Study are included as part of this data release.
