The module "Young people on the labour market" covers all compulsory variables according Commission implementing regulation (EU) 2022/2312 of 25 November 2022 on eight-yearly variables in the labour force domain on ‘young people on the labour market’, ‘educational attainment – details, including education interrupted or abandoned’ and ‘reconciliation of work and family life’ pursuant to Regulation (EU) 2019/1700 of the European Parliament and of the Council.

The sample used for the Labour force survey is a two-stage stratified cluster sample, which includes quarterly about 19.6 thousand households (representing about 0.65% sampling rate). The module module "Young people on the labour market" was carried out over a part (25%) of the LFS sample in each quarter and consisted of the households from the third wave. Due to the sampling approach used in the Labour force survey, the estimation of the parameters obtained from the survey could vary from those in the population due to sampling errors, errors due to non-response, errors in registration or processing etc.

Coefficients of variation (relative standard errors), and confidence intervals (i.e. the range of values that 95% of times would capture the true value in the population) are calculated for assessment of stochastic reliability of the estimates for main indicators.

The non-response rate for the module “Young people on the labour market” is 0.3% (of persons responded in regular LFS). 

The main results from the LFS modules are published after the reference year.

The main results from the module “Young people on the labour market" are presented on 17 October 2025.

Comparability across EU Member States is considered high due to use of harmonised concepts, variables, definitions and classifications.
