Labour Force Survey 2021, 4th Quarter

Statistics Norway established the Labor Force Survey (LFS) in 1972, and it has been conducted quarterly ever since. The LFS measures the population's participation in the labor market and provides comprehensive information on unemployment, employment, people outside the labor force, temporary employees, underemployed and other subgroups that are not captured by register-based statistics. This makes the LFS one of the most important sources of information about conditions in the Norwegian labor market.

Right from the start, the aim has been to ensure that the survey is comparable with similar surveys internationally. Today, the LFS is designed in accordance with the EU's statistical regulations to ensure consistent and comparable European statistics. The LFS data contains long time series, and although there have been some breaks in the time series due to changes in the questionnaire and data collection, the most central variables have been continuously included since the start. This makes it possible to present time series data for the employed, unemployed and people outside the labor force all the way back to 1972.

From 2020 to 2021, a significant break in the time series was necessary due to the implementation of a new framework regulation for European social statistics. The production system was revised in full, with changes in sampling, weighting, use of register data, and a new questionnaire, several changes were made to modernize and streamline data collection.

The dataset consists of a single quarter, along with a quarterly weight. The dataset should be used for a quarterly average rather than an annual distribution. If an annual average is desired, separate datasets are available.

挪威统计署（Statistics Norway）于1972年设立劳动力调查（Labor Force Survey, LFS），该调查自此之后按季度持续开展。LFS用于衡量人口的劳动力市场参与程度，可全面提供失业、就业、非劳动力群体、临时雇员、未充分就业人员，以及登记统计未覆盖的其他子群体的相关信息，使其成为挪威劳动力市场状况最重要的信息来源之一。

自创立伊始，该调查的核心目标便是确保其可与国际同类调查进行比较。如今，LFS的设计完全符合欧盟统计法规要求，以保障欧洲统计数据的一致性与可比性。LFS数据集包含长期时间序列数据，尽管因问卷调整与数据收集方式变更，时间序列曾出现若干断点，但核心变量自调查启动以来始终被纳入统计范畴，因此可回溯至1972年，获取就业人员、失业人员及非劳动力群体的时间序列数据。

2020年至2021年间，因欧盟社会统计新框架法规的实施，有必要对时间序列进行重大调整。此次全面修订了生产系统，涵盖抽样、加权、登记数据使用及问卷更新等多方面调整，以实现数据收集的现代化与流程优化。

本数据集仅包含单个季度的数据及季度权重，适用于季度均值分析而非年度分布统计。若需获取年度均值数据，可使用专用数据集。
