International Passenger Survey, 2019

<p>Users should note that currently the data covers the first three quarters of 2019 with four subject areas, termed 'Airmiles', 'Alcohol', 'Qregtown' and 'Qcontact'. One file is produced each quarter per subject area, and the dataset updated quarterly. These files can be joined together using the variables YEAR, SERIAL, FLOW and QUARTER.<br> <br> The depositor recommends that only expert users who are very familiar with the coding and weighting structures use these data, as limited support is available. Some considerable understanding of the data is required before meaningful analyses can be made; care must be taken when performing time series operations as codes can vary from year to year and not all variables from one year's dataset are used in other years. <br> <br> <b>Weighting the IPS</b><br> ONS advise that the variable 'fweight' included in the 'Qcont' dataset should be applied to get an overall weighted profile. This weight is set consistently over time.<br><br><span style="font-weight: bold;">New edition information</span><br>For the sec<span style="color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">ond edition (January 2020), data from Quarter 3 were added to the study.</span><br></p> The <i>International Passenger Survey</i> (IPS) aims to collect data on both credits and debits for the travel account of the Balance of Payments, provide detailed visit information on overseas visitors to the United Kingdom (UK) for tourism policy, and collect data on international migration.<br>

用户须知：当前数据集覆盖2019年前三季度，包含四个主题域，分别为Airmiles、Alcohol、Qregtown与Qcontact。每个主题域每季度生成一份数据文件，数据集按季度更新。上述文件可通过变量YEAR、SERIAL、FLOW及QUARTER进行关联合并。

数据保管方建议，仅对编码与加权结构极为熟悉的专业用户使用本数据集，因配套支持资源有限。开展有意义的分析前，需对本数据集具备充分的了解；进行时间序列操作时需格外谨慎，因编码规则可能随年度发生变化，且部分年度数据集所包含的变量未必会在其他年度沿用。

**IPS加权处理**：英国国家统计局（Office for National Statistics, ONS）指出，需使用Qcont数据集中的变量fweight以获取整体加权概况，该权重在时间维度上保持统一。

**新版数据集说明**：2020年1月发布的第二版数据集，新增了2019年第三季度的数据。

国际旅客调查（International Passenger Survey, IPS）旨在为国际收支旅游账户采集借贷方数据，为英国（United Kingdom, UK）旅游政策提供海外访客的详细出行信息，并采集国际移民相关数据。
