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年推出劳动力调查（Labor Force Survey, LFS），此后每季度开展一次调查。该调查旨在衡量人口的劳动力市场参与情况，并提供失业、就业、非劳动力群体、临时雇员、就业不足者及其他未被登记统计（register-based statistics）覆盖的细分群体的全面信息。这使得劳动力调查成为挪威劳动力市场状况最为重要的信息来源之一。

自项目启动之初，其核心目标始终是保障该调查可与国际同类调查进行比较。如今，该调查依照欧盟统计法规设计，以确保欧洲统计数据的一致性与可比性。劳动力调查数据集涵盖长期时间序列，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，但核心变量自项目启动以来始终得以保留。这使得我们可以追溯至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，为落实欧盟社会统计新框架法规，需对时间序列进行重大断点调整。本次全面修订了数据生产系统，涵盖抽样方法、加权规则、登记数据使用及问卷更新等多项调整，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数据及季度权重，适用于季度均值计算，而非年度分布统计。若需获取年度均值数据，请使用专用数据集。
