      <abstract xml:lang="en">&lt;P&gt;Abstract copyright UK Data Service and data collection copyright owner.&lt;/P&gt;&lt;p&gt;The &lt;i&gt;Opinions and Lifestyle Survey&lt;/i&gt; (formerly known as the ONS Opinions Survey or Omnibus) is an omnibus survey that began in 1990, collecting data on a range of subjects commissioned by both the ONS internally and external clients (limited to&amp;nbsp;other government departments, charities, non-profit organisations and academia).&lt;/p&gt;&lt;p&gt;&lt;p&gt;Data are collected from one individual aged 16&amp;nbsp;or&amp;nbsp;over,&amp;nbsp;selected from each sampled private household. Personal data include data on the individual, their family, address, household, income and education, plus responses and opinions on a variety of subjects within commissioned modules.&lt;/p&gt; &lt;p&gt;The questionnaire collects timely data for research and policy analysis evaluation on the social impacts of recent topics of national importance, such as the coronavirus (COVID-19) pandemic and the cost of living, on individuals and households in Great Britain.&lt;/p&gt; &lt;p&gt;From April 2018 to November 2019, the design of the OPN changed from face-to-face to a mixed-mode design (online first with telephone interviewing where necessary). Mixed-mode collection allows respondents to complete the survey more flexibly and provides a more cost-effective service for customers.&lt;/p&gt; &lt;p&gt;In March 2020, the OPN was adapted to become a weekly survey used to collect data on the social impacts of the coronavirus (COVID-19) pandemic on the lives of people of Great Britain. These data are held in the Secure Access study, SN 8635,&amp;nbsp;&lt;em&gt;ONS Opinions and Lifestyle Survey, Covid-19 Module, 2020-2022: Secure Access.&amp;nbsp;&lt;/em&gt;&lt;/p&gt; &lt;p&gt;From August 2021, as coronavirus (COVID-19) restrictions were lifting across Great Britain, the OPN moved to fortnightly data collection, sampling around 5,000 households in each survey wave to ensure the survey remains sustainable.&lt;/p&gt; &lt;p&gt;The OPN has since expanded to include questions on other topics of national importance, such as health and the cost of living. For more information about the survey and its methodology, see the ONS&amp;nbsp;&lt;a title="OPN Quality and Methodology Information" href="https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/opinionsandlifestylesurveyqmi"&gt;OPN Quality and Methodology Information&lt;/a&gt; webpage.&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Secure Access Opinions and Lifestyle Survey data&lt;/span&gt;&lt;/p&gt;&lt;/p&gt;&lt;p&gt;Other Secure Access OPN data cover modules run at various points from 1997-2019, on Census religion (SN 8078), cervical cancer screening (SN 8080), contact after separation (SN 8089), contraception (SN 8095), disability (SNs 8680 and 8096), general lifestyle (SN 8092), illness and activity (SN 8094), and non-resident parental contact (SN 8093). See &lt;a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000043"&gt;Opinions and Lifestyle Survey: Secure Access&lt;/a&gt; for details.&lt;/p&gt;</abstract><abstract xml:lang="en">&lt;B&gt;Main Topics&lt;/B&gt;:&lt;BR&gt;Each month's questionnaire consists of two elements: core questions, covering demographic information, are asked each month together with non-core questions that vary from month to month.</abstract><abstract xml:lang="en">The non-core questions for this month were:&lt;br&gt; GP Accidents (Module 78n): this module asked about accidents the respondent had had where help was sought that could have involved a doctor e.g. doctor's surgery, hospital.&lt;br&gt; Family History (Module 123): This module asks about the different kinds of families respondents have lived in. It looks at the types of family the respondent has grown up in (up until the age of 16) and what type of parents they have been (from the age of 16).&lt;br&gt; Employees Working Practices (Module 142): this module is only asked of current employees. The module asks about aspects of work      including method of payment/working conditions, opportunities for promotion, flexible working, autonomy and influence. &lt;br&gt; Self-Classification of Job Group (Module 145): this question is asked of all those who are currently working or have ever had a job. Respondents are asked to classify their occupation as non-manual or manual.&lt;br&gt; Time to First Pregnancy and Infertility (Module 146): this module asks questions about fertility and whether the respondent (or their   partner) have experienced problems in conceiving. The questions focus on Time To Pregnancy (TTP) as a measure of infertility.&lt;br&gt;</abstract>
