British Household Panel Survey Combined Work-Life History Data, 1990-2005

The <i>British Household Panel Survey</i> (BHPS), which ran for 19 waves from 1991-2009, collected extensive information on respondents' labour market status at three points: at the time of interview at each wave of the panel; throughout the period between 1 September a year before the interview date; and retrospectively from when the respondent first left full-time education. Because the retrospective information has been collected in two tranches (one focusing on employment status, the other on occupational information), there are four different types of labour market history information, located in different files in the BHPS database. This complexity is a necessary aspect of longitudinal information, but had inhibited use of the work-life history data. In order to better facilitate such use, a set of 'reconciled' files, the <i>British Household Panel Survey Combined Work-Life History Data</i>, was created, constituting single continuous records each containing all the information of a particular type in a single location. The first part of the exercise was to take 'current status' information for each wave and combine it with the inter-wave history, and then to combine the waves thus creating a continuous record from September 1990 to the latest wave. The second stage was to take the lifetime employment status history collected at Wave 2, and the lifetime occupational history collected at Wave 3, and to combine each of them with analogous information drawn from the combined panel file, thus creating employment and occupational histories that stretch from the labour market entry to the latest wave. The third stage was to combine these two extended lifetime histories into a single record which contains both employment status information (with good information about non-employed spells) and occupational information (i.e. details about the job held during each employed spell). Further details of the methods used are included in the following technical paper: Halpin, B. (1997) <i>Unified BHPS work-life histories: combining multiple sources into a user-friendly format</i>, Technical Papers of the ESRC Research Centre on Micro-Social Change, 13, Colchester: University of Essex. <br>

Users are recommended to use these data in conjunction with the main <a href="http://discover.ukdataservice.ac.uk/series/?sn=200005" title="BHPS">BHPS</a> dataset. It should also be noted that this dataset is in package format; see READ file for further details on formats and use.<br>

For the fifth edition (November 2006), the files 'newpan', 'xlempe' and 'xljobe' were updated. The rest of the data and documentation remain unchanged.<br>

&lt;i&gt;英国家庭面板调查（British Household Panel Survey，BHPS）&lt;/i&gt;于1991年至2009年间开展了19轮调查，采集了受访者在三个时间节点的劳动力市场状况详尽信息：一是各轮面板访谈当日的就业状态；二是访谈日期前一年9月1日至访谈当日的时段内的就业情况；三是受访者首次脱离全日制教育以来的回溯性就业历史。由于回溯性信息分两组收集（一组聚焦就业状态，另一组聚焦职业信息），BHPS数据库的不同文件中存储了四类不同的劳动力市场历史信息。这种复杂性是纵向调查数据的固有特征，但却制约了工作生涯历史数据的使用。<br><br>为更好地推动该类数据的应用，研究团队构建了一套“整合后”文件，即&lt;i&gt;英国家庭面板调查合并工作生涯历史数据集（British Household Panel Survey Combined Work-Life History Data）&lt;/i&gt;，该数据集为每位受访者生成单条连续记录，将特定类型的全部信息集中存储于同一位置。本次整合工作分为三个阶段：第一阶段将各轮调查的“当前就业状态”信息与轮间就业历史信息合并，随后将各轮数据整合为1990年9月至最新一轮调查的连续记录；第二阶段将第2轮调查采集的终身就业状态历史与第3轮调查采集的终身职业历史，分别与合并面板文件中的同类信息进行整合，由此生成从劳动力市场准入至最新一轮调查的完整就业与职业历史记录；第三阶段将这两类扩展后的终身历史记录合并为单条记录，同时涵盖就业状态信息（包含非就业时段的完整记录）与职业信息（即各就业时段的岗位细节）。相关方法的更多细节可参阅以下技术论文：Halpin, B.
