International Passenger Survey, 2018

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> <p>The data covers 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.</p><p> 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.</p><p><span style="font-weight: bold;">Latest edition information</span></p><p> </p><p>For the third edition (June 2022), a revised Qcontcust 2009-2019 data file was added to the study. It includes the additional sampling design variables shiftWeight, NonRespWeight, minimumsWeight, sampTrafficWeight, unsampTrafficWeight, OLD_imbalanceWeight, shiftWeightgrp, NRWeightgrp, minsWeightgrp, sampTrafficWtgrp, UnsampwgtPortgrp and UnsampwtRegiongrp. The data file includes all years from 2009-2019 and users will need to filter the data by year to see cases for individual years.<br></p>

《国际旅客调查》（International Passenger Survey，IPS）旨在为国际收支平衡表中的旅行账户收集贷方与借方数据，为英国（UK）旅游政策提供海外访客的详细访问信息，并收集国际移民相关数据。<br> <p>该数据覆盖四个主题领域，分别称为“Airmiles”“Alcohol”“Qregtown”和“Qcontact”。每个主题领域每季度生成一个文件，数据集每季度更新一次。这些文件可通过变量YEAR、SERIAL、FLOW和QUARTER进行关联。</p><p>数据提供方建议仅由熟悉编码与加权结构的专业用户使用这些数据，因为可用支持有限。在进行有意义的分析前，需对数据有相当程度的理解；执行时间序列操作时需谨慎，因为编码可能逐年变化，且并非所有年份数据集中的变量都适用于其他年份。</p><p><span style="font-weight: bold;">最新版本信息</span></p><p> </p><p>对于第三版（2022年6月），修订后的Qcontcust 2009-2019数据文件已添加至本研究。该文件包含新增的抽样设计变量shiftWeight、NonRespWeight、minimumsWeight、sampTrafficWeight、unsampTrafficWeight、OLD_imbalanceWeight、shiftWeightgrp、NRWeightgrp、minsWeightgrp、sampTrafficWtgrp和UnsampwtRegiongrp。该数据文件涵盖2009-2019年的所有年份，用户需按年份筛选数据以查看各年度的案例。<br></p>
