Labour Force Survey 4. quarter 1983 - 1. quarter 1985, panel

Labour Force Survey, 4. quarter 1983 - 1. quarter 1985, panel (6 quarters).

As of the 1st quarter of 1972, SSB has conducted official quarterly labour force surveys (LFS). These surveys aim to give the labour force authorities (and other people interested) knowledge of the occupational structure of the population and how it develops over time. The surveys are meant to give a foundation and statistical material for occupational prognoses and labour research.

In the Labour Force Surveys each respondent is interviewed for two subsequent quarters, followed up by a two quarter break. Then they are again followed up with two subsequent quarters.
The first complete edition of LFS is the Labour Force Survey of 1972. Such statistics was originally intended to be a more analytical supplement to the monthly employment statistics which were based on the National Insurance membership index. The statistics was based on the national insuranse index until the sickness benefit was included in the national insuranse system januar 1st 1971. Gradually LFS has evolved to become the main source of knowledge about the condition and trends in the labor market.

Summary of AKU panels with detailed explanations for panel files:
Data collection for the LFS was started somewhat experimental in 1971, but the data are first published in 1972. It may be helpful to look at the following section of the detailed view:

Panel files are created by linking four interviews from an ordinary interview round of the LFS. In the table above this means one could connect all the pools (lines) labeled X. Participation 4th time is used as the criterion for the selection process.
In 1975 there was a break in the panel systematics, see 1975. The Labour Force Survey of 1976, adopted a slightly modified questionnaire and you came back to the original 6-quarterly rotation schedule which have been stable since.

If one looks at a particular column, for example 1st quarter of 1984, we will see that 1/4 of the respondents are included for the fourth time, for the third time, etc. The total sums the the material for one block. Quarterly weighting allows one such block (column) to be balanced with national figures. To give proper weighted figures for a annual volume consisting of four quarters, the quarterly weights has to be divides by 4.

The panels goes horizontally and each panel will have 4 weights, one for each quarter. Although they do not differ much, the weights will be prepared independently and each of them should be used for the data which the quarterly weight is made. Weighted figures apply to a pool, which means approx. 25% of the total quarterly sample, and one has to multiply by 4 to get the approximate national quarterly figures.

By "Approximate national quarterly figures" it means that differences from the quarterly national weighted figures can appear, because of the selections and whitdrawal in the connection of the panels. Because of the whitdrawal inflated numbers will be lower than the national total figures. The main point of the weights is not to give national totals, but rather to ensure the best possible representation.

This panel consider pool 52 in the table above.

1983年第四季度至1985年第一季度劳动力调查（Labour Force Survey, 以下简称LFS）面板数据集（共6个季度）。

自1972年第一季度起，挪威统计局（SSB）便正式开展季度劳动力调查（LFS）。该调查旨在为劳动力管理部门及其他相关从业者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研究提供基础数据与统计资料。

在劳动力调查中，每名受访者会连续接受两个季度的访谈，随后中断回访两个季度，之后再次连续接受两个季度的访谈。
1972年的劳动力调查为该系列的首个完整版本。此类统计最初旨在作为基于国民保险参保指数的月度就业统计的补充分析工具。在1971年1月病假津贴纳入国民保险体系之前，该统计数据均依托国民保险指数编制。此后，LFS逐步发展为了解劳动力市场状况与发展趋势的核心信息来源。

面板文件通过将LFS常规访谈周期中的四次访谈记录关联整合而成。上表中，可将所有标记为X的池（行）进行关联，选取标准为受访者的第四次参与记录。
1975年，面板系统的编制逻辑出现中断，详见1975年相关说明。1976年的劳动力调查采用了小幅修订的问卷，并回归至最初的6季度轮换机制，该机制自此保持稳定。

若观察某一特定列，例如1984年第一季度，可发现四分之一的受访者分别处于第四次、第三次等参与周期。该列总计构成一个数据块。通过季度加权，可使该数据块（列）与全国统计数据保持平衡。若要计算由四个季度组成的年度总量的加权数据，需将季度权重除以4。

各面板按横向排布，每个面板包含4个权重，分别对应四个季度。尽管权重差异较小，但仍会独立编制，且需将权重与对应季度的数据匹配使用。加权数据适用于单个池，即约占季度总样本量25%的子集，若要估算全国季度总量，需将该子集的加权数据乘以4。

此处的“近似全国季度总量”指由于面板数据的筛选与样本退出机制，可能与全国季度加权统计数据存在差异。由于样本退出，子集的加权数值会低于全国总量。权重设置的核心目的并非直接生成全国总量，而是尽可能确保样本的代表性。

本面板对应上表中的池52。
