An optimal sample allocation technique was used, together with new register employment status stratification, resulting in over-sampling of unemployed persons. This leads to better precision in estimates of the unemployment rate, a key output indicator for the survey. A new age-group (75-89 years) was included in the population definition and is sampled from in a separate stratification process. The overall sample size was adjusted down to allocate some resources to a sub-sample wave of all household members. This allows required data deliveries of household statistics not able to be met earlier. A supplementation plan was established to ensure all age-groups are represented in the survey in each wave.

The Norwegian Labour Force Survey sampling design
In 2021, many changes were implemented in the Norwegian Labour Force Survey (NLFS). The sampling plan was changed to better reflect the main output goals for the survey. It included moving to an individual sampling unit, allowing new stratification variables and allocations.
