Precision calculations are performed on all variables.

The precision indicators (standard deviation or coefficient of variation, 95% confidence interval) take into account errors due to sampling, correction for total nonresponse, calibration and winsorisation, but not the error due to correction for partial nonresponse.

Due to a large number of units that were not returned without information, they had to be reweighted. The share of out-of-scope units in the population is estimated at 27%. It is 1% in the employing part and 29% in the non-employing part. Out-of-scope units are excluded from the usable data.

The total non-response rate for the survey was 25.1%.

The weighted nonresponse rate due to the presence of units not returning without information is 23.7%.
