Labour Force Sample Survey 1st quarter 1975 - 2nd quarter 1976, panel file

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.

This file cover data collected in 1st and 2nd quarter 1975 and 1st and 2nd quarter 1976. The criterion to be included in the file is interview participation in the two last quarters. In the overview this is group 17.

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.

The 1976 Labour Force Survey also adopted a slightly modified questionnaire and it returned to the original six-quarter rotation schedule. The new questionnaire meant that people in the group and family workers temporarily absent from work were identified in a better way. This resulted in approximately 30 to 35,000 more were counted as employed. The group job seekers without work income was also expanded to include involuntarily laid off. The questions of under- and over-employment in the original form was deleted.

SSB自1972年第一季度起开展官方季度劳动力调查（Labor Force Survey, LFS）。该调查旨在为劳动部门及其他相关方提供关于人口职业结构及其随时间演变的信息。这些调查为职业预测和劳动力市场研究提供了基础数据与统计资料。在劳动力调查中，受访者会连续两个季度接受访谈，随后间隔两个季度后，再次连续两个季度接受访谈。1972年劳动力调查是首个完整的年度劳动力调查。最初，这类统计数据旨在作为基于保险基金成员档案的月度就业统计的补充，以提供更具分析性的信息。然而，随着1971年1月1日医疗保险被纳入国家保险计划，基于保险基金的统计数据逐渐停用，而劳动力调查则逐步发展成为了解劳动力市场状况的主要信息来源。

本文件涵盖1975年第一、二季度及1976年第一、二季度收集的数据。纳入本文件的标准为受访者参与了最后两个季度的访谈，在概述表中对应第17组。

面板文件通过关联劳动力调查常规访谈轮次中的四次访谈创建。在上表中，这意味着可以连接所有标记为X的组（行）。第1组被移除，因为访谈始于1971年第四季度。四次参与被用作筛选标准，因此未参与第四次访谈的受访者均被排除在外。

1976年劳动力调查还采用了经过微调的问卷，并恢复了最初的六季度轮换计划。新问卷能更准确地识别群体中的人员及临时缺勤的家庭工人。这导致约3万至3.5万人被新增统计为就业人员。无工作收入的求职者群体范围也被扩大，纳入了非自愿失业人员。原始问卷中的就业不足与过度就业相关问题已被删除。
