ONS Opinions and Lifestyle Survey, Covid-19 Module, 2020: Secure Access

<p>The aim of the <span style="font-style: italic;">ONS Opinions and Lifestyle Survey, Covid-19 Module, 2020</span> study is to help understand the impact of the coronavirus (Covid-19) pandemic on people, households and communities in Great Britain. It is a weekly survey initiated in March 2020 and may run into 2021. It is an ad-hoc household survey to measure the attitudes and behaviour towards the Covid-19 in general. The study allows the breakdown of impacts by at-risk age, gender and underlying health condition.</p><p>The weekly samples were randomly selected from those that had previously completed other ONS surveys (e.g., <span style="font-style: italic;">Labour Market Survey</span>, <span style="font-style: italic;">Annual Population Survey</span>).  From each household, one adult was randomly selected but with unequal probability: younger people were given higher selection probability than older people because of under-estimation in the samples available for the survey.<br><br>For the second edition (February 2021), data from Wave T (July 2020) to Wave AM (December 2020) have been added. The documentation has also been updated to reflect the extended time period.<br></p>

本研究为《2020年英国国家统计局（Office for National Statistics, ONS）民意与生活方式调查新冠专题模块》，旨在探究新冠疫情（coronavirus, Covid-19）大流行对英国大不列颠地区民众、家庭及社区的影响。该调研自2020年3月启动，为周度调查，计划持续至2021年，属于专项家庭调查，用于整体衡量公众对新冠疫情的态度与行为表现。本研究支持按高风险年龄段、性别及基础健康状况对疫情影响进行细分分析。

本次周度调研的样本随机抽选自此前已完成其他英国国家统计局调查的人群（如《劳动力市场调查（Labour Market Survey）》、《年度人口调查（Annual Population Survey）》）。调研从每个受访家庭中随机选取一名成年人，但采用非均等概率抽样：由于现有可用样本对年轻群体的占比存在低估，因此为年轻群体赋予了更高的入选概率。

第二版调研（2021年2月发布）新增了从T波（2020年7月）至AM波（2020年12月）的调研数据，同时更新了配套文档以适配延长后的调研周期。
