Labour Force Survey 3. Quarter 2001 - 2. Quarter 2003, Panel

Labour Force Survey 3. Quarter 2001 - 2. Quarter 2003, Panel (8 quarters) As of the 1st quarter of 1972, SSB has conducted official quarterly labour force surveys (AKU). 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 1996, AKU was significantly revised: The questionnaire, the file description and the standard for coding of industry and occupation. The data collection also changed to CATI - Computer Assisted Telephone Interviewing. A new classification of industry was put into use (NOS C 182, based on the EU standard NACE, Rev.1). This standard was updated in 2002 and 2007. Also, the new Norwegian standard classification of occupations (STYRK) based on ISCO 88 was used from 1996 and onwards. The variable indicating socio-economic status was omitted, as a similar variable was not developed in the new occupational classification. Every second quarter AKU is extended with a number of questions to collect data accordant to Eurostats / EUs spesifications. From 1996, the rotation schedule changed, each family now attends eight consecutive quarters. As of 1996 the selection shedule was changed as well with stratification at the county level. Summary of AKU panels with detailed explanations for panel files: Data collection for the new rotation plan as the basis for this file is shown below. Participants in the 4th quarter of 1997 is the first batch of 8 possible completed interviews.

In the table above means that one could connect all the batches (lines) marked X. Participation 8 times used as a criterion for selection. Annual files and quarterly files consist of respondents who are participating for 1st time, 2nd time, and so on. The weights allow such cross-sections (columns) can be balanced with national figures. If 4 quarters is merged into an annual volume, the quarterly weights be divided by four to attain correct weighted annual numbers. Each panel (panel files: horisontal in the table) will have a weight compiled for each quarter. Although the weights do not differ much from each other, they will be compiled independently, and each weight should be used only for the data which the quarterly weight is made for. Weighted numbers is valid for one pool, which means ca 12,5 % (1/8) of a total quarterly selection. Therefore, one must multiply by 8 to 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 is not to give national totals, but rather to ensure the best possible representation.

2001年第三季度至2003年第二季度劳动力调查面板数据（共8个季度）
自1972年第一季度起，SSB便开展官方季度劳动力调查（AKU）。该调查旨在为劳动力管理部门及其他相关方提供人口职业结构及其动态演变的相关信息，为职业预测与劳动力研究提供基础数据与统计支撑。
1996年，AKU迎来重大修订，涵盖问卷内容、数据文件说明以及行业与职业编码标准。数据采集方式同步调整为计算机辅助电话调查（CATI, Computer Assisted Telephone Interviewing）。同时启用基于欧盟NACE Rev.1标准的挪威行业分类标准NOS C 182，该标准分别于2002年与2007年完成更新。自1996年起，调查采用基于国际标准职业分类88版（ISCO 88）的新版挪威职业分类标准（STYRK）。由于新版职业分类体系未开发对应社会经济地位的变量，原有的社会经济地位指示变量被移除。
每季度的AKU调查会增设若干问题，以符合欧盟统计局（Eurostats）及欧盟的规范要求采集数据。1996年起，调查轮换机制调整为：每个家庭将连续参与8个季度的调查。同年，抽样方案同步调整，以县级行政单位为层级开展分层抽样。
以下为本数据集所依托的新轮换方案数据采集说明：1997年第四季度参与调查的样本组为首批完成8次完整访谈的样本。
面板文件通过将劳动力调查一轮常规访谈中的8次访谈记录关联整合而成。上表中带"X"标记的行即为可关联的样本批次，以连续参与8次调查作为样本入选标准。

年度文件与季度文件包含首次参与、第二次参与等不同参与频次的受访者样本。权重设置可保证各截面（即表格中的列）数据与全国统计数据保持平衡。若将4个季度的数据合并为年度数据集，需将季度权重除以4，以得到准确的加权年度统计值。每个面板（即表格中的横向行）均会为对应季度生成专属权重。尽管各权重之间差异较小，但均为独立计算所得，且仅可用于对应季度生成的数据集。
加权统计值仅适用于当前样本组，约占季度总抽样样本的12.5%（即1/8），因此需将加权结果乘以8以近似得到全国季度统计值。此处的"近似全国季度统计值"指因面板构建过程中的抽样与样本流失问题，加权结果与全国季度加权统计值可能存在差异。受样本流失影响，加权估算值将低于全国总量统计值。
权重设置的核心目的并非用于生成全国总量统计值，而是尽可能保障样本的代表性。
