HMIP Prisoner Survey: Adults in England and Wales, 2000-2023: Special Licence Access

<p>The HMIP (His Majesty's Inspectorate of Prisons) Prisoner Surveys (also formerly known as Detainee Surveys) are part of the Inspectorate's duties to inspect prisons. Surveys of prisoners have been carried out systematically since 2000 at institutions being inspected, to gain important insight into detainees' experiences of offender management whilst in custody.</p><p>Prisoners are issued with the survey questionnaire to return to the HMIP team, which processes the data to inform inspections of individual institutions and the HMIP annual reports.</p><p>The survey is grouped into topics/themes of questions with response categories, as well as providing space for prisoners to add additional comments (such text comments are not included in these datasets).</p><p>The specific objectives of the HMIP Prisoner Survey series are as follows:<br></p><ul><li>to produce data that are comparable as possible over time and between custodial institutions;</li><li>to provide data for a large and representative sample of adult prisoners in England and Wales. So far, over 20 years' worth of data has been collected.

The document 'end_user_licence_group_changes', available with the EUL version, SN 9161, details the differences between the two versions.

Other changes include a minor modification in how the datasets are organised. They are now categorised not only by publication year but also by questionnaire version. In some years, there was a separation in terms of gender (men and women) and prison type (open and closed prisons) when there was a survey difference. These changes are structural, allowing for more specific data segmentation. Additionally, a few corrections in the data entries have been made.<br></p>

英国监狱监察局（His Majesty's Inspectorate of Prisons, HMIP）囚犯调查（前身为被羁押者调查）是该局监狱巡查职责的核心组成部分。自2000年起，项目组已在待巡查的监管机构中系统性开展囚犯调查，以深入掌握被羁押者在羁押期间接受罪犯管理的实际体验。

调查问卷将发放给囚犯，完成后交由英国监狱监察局团队回收；团队会对采集到的数据进行标准化处理，相关成果将用于支撑各监管机构的专项巡查及该局年度报告的撰写。

本次调查以主题模块划分问题，设置了标准化作答选项，同时预留了供囚犯补充意见的空间（此类文本评论未纳入本数据集）。

英国监狱监察局囚犯调查系列的具体目标如下：
1. 生成可在时间维度及不同监管机构间进行横向、纵向比较的统一口径数据；
2. 为英格兰及威尔士地区具有代表性的成年囚犯大样本群体提供调研数据。目前该项目已积累了20余年的调研数据。2020/2021年度的调查受英国监狱监察局COVID-19防疫限制措施影响。

【终端用户许可版与特殊许可版】
英国监狱监察局囚犯调查共有两个版本留存于英国数据服务中心（UKDS）：一是终端用户许可（End User Licence, EUL）版（编号SN 9161），需完成注册并遵循标准访问规则；二是内容更详实的特殊许可（Special Licence, SL）版（编号SN 9068），该版本存在额外的访问限制。与EUL版（SN 9161）一同提供的《end_user_licence_group_changes》文档，详细说明了两个版本的差异。用户在申请访问SL版前，应先获取EUL版以确认其是否符合自身研究需求。

【最新版本信息】
2023年10月发布的第二版调查中，项目新增了2020/2021及2022/2023年度的调研数据。其他调整包括对数据集组织方式的小幅优化：如今数据集不仅按发布年份分类，还会根据问卷版本进行划分。部分年度的调查因存在差异，会按性别（男性、女性）及监狱类型（开放式、封闭式监狱）进行拆分。此类调整均为结构性优化，可实现更精细化的数据细分；此外，本次更新还对部分数据条目进行了修正。
