13. Accuracy and reliabilityTop
13.1. Overall accuracy

In this research, we distinguish between two types of errors: sampling and non sampling.

The survey is conducted on a random sample. The sample selection box is based on the 2011 Census. The sample plan is defined in such a way that the grades for the main assessment domains are of satisfactory accuracy.

Of the non-sampling errors, there are:

  • coverage errors resulting from the inaccuracy of the sampling frame formed on the basis of the 2011 Census;
  • errors resulting from the exclusion of census circles with fewer than 20 households (cut-offs) recorded in the 2011 Census;
  • Measurement and non-response errors that are inevitable but the instruments, organization of collection and data entry are such that these errors are minimized.
13.2. Sampling error

The sample for the survey is two-stage stratified, with census circles as primary and households as secondary units. The sample selection box for the first stage, is a list of census circles with 20 or more households, and for the second stage, lists of households for the selected census circles. The rating system corresponds to a selection procedure in which the units of the first stage are selected in proportion to the size and with repetition, and the units of the second stage are simply random without repetition. To make the estimates from the sample representative of the observed general population, each household in the sample was assigned a weighting (expansion factor). The baseline weighting resulting from the applied sample design was corrected for non-response and adjusted for population values ​​for 2022. Two weights were calculated. Household weight, which serves as an expansion factor for the data collected by the household questionnaire and the weighting for persons aged 16-74 over the years for the data collected by the individual questionnaire. The household weight was adjusted to the estimated number of households for 2022, applying the post-stratification method. The face weight was adjusted to the current demographic estimates for 2022, based on gender, 10 years of age, and completed school, using the post-stratification method.

13.3. Non-sampling error

The response rate of observation units (households and persons) is  90.6%. The reasons for non-response are: no contact with the household / person, refusal to cooperate, inability to cooperate due to language barrier, illness or other reasons and disregard of incomplete or poor quality questionnaires.

The baseline weighting resulting from the sample design applied has been corrected for non-response and adjusted for 2021 population values. Two weights were calculated. Household weight, which serves as an expansion factor for the data collected by the household questionnaire and the weighting for persons aged 16-74 over the years for the data collected by the individual questionnaire. The household weight was adjusted to the estimated number of households for 2021, applying the post-stratification method. The face weight was adjusted to the current demographic estimates for 2021, based on gender, 10 years of age and graduation using the post-stratification method.

15.2. Comparability - over time

Time series 2009-2022. For information: there are interrupt series, the reasons for the break of the series are:

- change the Eurostat questionnaire and eject certain variables from the questionnaire

- change the scope of certain variables, some variables are divided into two different variables, thus eliminating the possibility of a time series
