British Household Panel Survey Combined Work-Life History Data, 1990-1999 (M863)

Abstract copyright UK Data Service and data collection copyright owner. The British Household Panel Survey (BHPS) collects 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 it has inhibited use of the work-life history data. In order to better facilitate such use, a set of 'reconciled' files, the British Household Panel Survey Combined Work-Life History Data, has been created, constituting single continuous records each containing all the information of a particular type in a single location. The first part of the exercise is 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 is 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 is 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) Unified BHPS work-life histories: combining multiple sources into a user-friendly format, Technical Papers of the ESRC Research Centre on Micro-Social Change, 13, Colchester: University of Essex. Users are recommended to use these data in conjunction with the main BHPS dataset. It should also be noted that this dataset is in package format; see READ file for further details on formats and use.本数据集的版权归英国数据服务中心（UK Data Service）及数据采集版权方所有。英国家庭面板调查（British Household Panel Survey, BHPS）会从三个时间维度收集受访者的劳动力市场状况信息：一是各波次访谈进行时的当下状态；二是访谈日期前一年9月1日起至访谈当日的区间内的就业状况；三是受访者首次脱离全日制教育以来的回顾性就业历史。由于回顾性信息分两批采集——一批聚焦就业状态，另一批聚焦职业信息，因此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。这种信息复杂性是纵向研究数据的固有特征，但也制约了工作生涯历史数据的使用效率。为更好地推动该类数据的复用，研究团队构建了一套“整合修正版”文件——英国家庭面板调查组合式工作生涯历史数据集（British Household Panel Survey Combined Work-Life History Data），该数据集将特定类型的全部信息整合至单一位置，形成单条连续记录。本次数据整合工作分为三个阶段：第一阶段，将各波次的“当前状态”信息与波次间的历史信息进行合并，进而构建出1990年9月至最新调查波次的连续就业历史记录；第二阶段，将第二波采集的终身就业状态历史、第三波采集的终身职业历史，分别与从组合式面板文件中提取的同类信息进行合并，最终生成从劳动力市场入职直至最新调查波次的完整就业与职业历史数据；第三阶段，将上述两类扩展后的终身历史数据合并为单条记录，该记录同时涵盖就业状态信息（包含非就业时段的详细记录）与职业信息（即各就业时段的岗位细节）。有关本次数据整合所采用方法的详细说明，请参阅以下技术论文：哈尔平（Halpin, B.）（1997）《统一化英国家庭面板调查工作生涯历史：将多源数据整合为易用格式》，载于《经济与社会研究委员会微观社会变化研究中心技术报告》第13期，埃塞克斯大学科尔切斯特分校。建议用户将本数据集与BHPS主数据集结合使用。同时需注意，本数据集采用包格式存储，有关数据格式与使用方法的详细说明请参阅配套READ文件。
