Labour Force Survey 1st quarter 1983 - 2nd quarter1984, 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.

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. Looking at a particular column, for example. Q1 1983, we will see that 1/4 of respondents are included for the 4th time, the 3rd time etc. The total sum of the material for one quarter. Quarterly weights allows one such block (column) to be balanced with national figures. If taking 4 groups and turning them into a year file the weights must be divided by 4 to give proper weighted figures. Panel files goes in the other direction (horizontally) and each panel will have four weights, one for each quarter, and although they do not differ much will they be prepared independently and each weight should be used only for data from the quarterly weight is made. Weighted figures are for a pool, ie ca. 25% of the total quarterly sample and must therefore multiply by 4 to get approximately the national quarterly. With "almost national quarterly" means that since panel connectors innebærerer a certain selection, as it may cause minor differences from the weighted national figures one gets for each quarter This panel file covers group 49 in the table above.

挪威统计局（Statistics Norway, SSB）自1972年第一季度起开展官方季度劳动力调查（Labor Force Survey, LFS）。本次调查旨在为劳动主管部门及其他相关方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基础依据与统计素材。
在LFS调查中，受访者需连续接受两个季度的访谈，间隔两个季度后，再次连续开展两个季度的访谈。1972年劳动力调查是首次完整开展的年度LFS调查。最初，该类统计数据旨在作为基于保险基金参保档案的月度就业统计的补充分析工具；然而，自1971年1月1日健康保险纳入国民保险计划后，基于保险基金的统计数据便不再使用，LFS也逐渐演变为了解劳动力市场现状的核心信息来源。

面板数据集通过关联LFS常规访谈周期中的四次访谈记录生成。在上表中，这意味着可将所有带有标记X的行（组别）进行关联整合。第1组被移除，因其访谈始于1971年第四季度。本次数据集以完成4次访谈作为入选标准，因此未参与第4次访谈的受访者均被排除在外。
1975年，SSB调整了抽样策略，1973年或1974年启动、本应在1975年开展至少一次访谈的组别均被移除。以某一列为例，如1983年第一季度列，可发现1/4的受访者为第4次参与调查，另有部分为第3次参与，依此类推。
单季度数据集的总样本量可通过季度权重实现与全国统计数据的均衡。若将4个组合并为年度数据集，则需将权重除以4，以获得正确的加权统计值。
面板数据集的构建方向为横向（即按季度维度整合），每个面板均包含4个权重，分别对应四个季度；尽管各权重间差异不大，但仍需独立生成，且每个权重仅可用于对应季度生成的调查数据。加权统计值对应一个子样本池，约占季度总样本量的25%，因此需将其乘以4，以得到近似的全国季度统计值。
所谓“近似全国季度统计值”，是指由于面板数据关联过程涉及特定抽样设计，可能导致其与单季度加权全国统计数据间存在细微差异。本面板数据集对应上表中的第49组。
