Labour Force Survey 3rd quarter 1979 - 4th quarter 1980 panel file, old estimation

SSB has conducted official quarterly labor force surveys (LFS) from Q1 1972. The survey aims to provide labor authorities and others knowledge about the occupational structure of population and development over time. The surveys provide the basis and statistical material for occupational forecasting and labor market research. In the LFS respondents are interviewed two consecutive quarters, then after two more quarters they are interviewed again in two consecutive quarters. Labour Force Survey 1972 is the first complete LFS year long survey. Originally it was intended that such statistics would be a more analytical supplement to the monthly employment statistics based on the insurance fund membership files. The insurance fund-based statistics, however, fell away when health insurance was included in the National Insurance Scheme from 1 January 1971, the LFS has gradually evolved to become the main source of knowledge about the state of the labor market.

Panel files are created by linking four interviews from an ordinary interview round in LFS. In the table above this means that one could connect all the groups (lines) marked X.
Group 1 is removed because the intweviews started 4th quarter 1971.
Participation 4 times is used as a selection criterion, therefore everyone that didn't participate in the 4th interview has been omitted.
In 1975 SSB changed selection strategy. The groups that were left out due to this (started in 1973 or 1974, should've had one or more interviews in 1975) are removed.

This panel file covers group 35 in the table above.

挪威统计局（Statistisk Sentralbyrå, SSB）自1972年第一季度起开展官方季度劳动力调查（Labour Force Survey, LFS）。本调查旨在为劳动主管部门及相关机构提供人口职业结构及其随时间演变的相关信息，为职业预测与劳动力市场研究提供核心依据与统计素材。在LFS的调查设计中，受访者需接受连续两个季度的访谈，间隔两个季度后，再次开展连续两个季度的回访。1972年劳动力调查是首个完整的年度LFS调查。最初，该类统计本计划作为基于保险基金会员档案的月度就业统计的分析性补充，但1971年1月健康保险被纳入国民保险计划（National Insurance Scheme）后，原基于保险基金的统计方案被废止，LFS也逐步演变为了解劳动力市场状况的权威信息来源。

面板文件通过将LFS普通访谈轮次中的四次访谈数据关联构建而成，上表即意味着可将所有标记为X的组别（行）进行关联。由于访谈于1971年第四季度启动，第1组被移除。本次筛选以参与四次访谈为标准，因此未参与第四次访谈的对象均已被剔除。1975年SSB调整了筛选策略，原因该调整被排除的组别（1973年或1974年启动，本应在1975年开展一次或多次访谈）均已被移除。本面板数据集对应上表中的第35组。
