    Weighting

    Non-response Weight: Method

    "[...] united calibration for all the waves was used as the method for correcting non-response. The achieved sample was re-weighted using the integrated calibration technique (producing the same weights on household and personal level). This technique ensures that the weighted sample structure corresponds to a set of known external population characteristics. The calculations were implemented using the CALMAR software in SAS." (Eurostat (2017). National Reference Metadata in ESS Standard for Quality Reports Structure (ESQRS), CZ, p. 5.)

    Coverage Adjustment Weight: Method

    "The following calibration variables were used:
    Number of inhabited dwellings in each NUTS3 region, subdivided into family houses (detached and semi-detached houses) and flats, based on the 2001 Census and 2011 Census continuously updated from administrative sources of construction authorities
    Population characteristics:
    • Population totals in each NUTS3 region (from demographic statistics)
    • Economic activity characteristics for the Czech Republic
    • Number of employees - derived from the number of employees in the economy based on the Labour Force Survey (LFS) results and company
    reporting
    • Demographic characteristics at the national level (based on the demographic statistics):
    • Age groups (0-15, 16-24, 25-34, 35-44, 45-54, 55-64, 65-74, 75+)
    • Gender at the national level
    • Municipality size at the national level (below 2 000 inhabitants, 2 000 - 9 999, 10 000 - 49 999, 50 000+ inhabitants)" (Eurostat (2017). National Reference Metadata in ESS Standard for Quality Reports Structure (ESQRS), CZ, p. 5.)

    Coverage Adjustment Weight: Method

    "The final step of the calculation of the weights was the calculation of the calibration factors. By the calibration procedure the household weights are adjusted so that they reproduce the totals of external variables. For the calibration of weights we used SAS Macro Calmar. The calibration was performed in an ‘integrative’ way. It means that both household and individual external information used in a singleshot calibration at household level. The new weights were calibrated on the number of persons in private households in gender–age groups by regions / groups of counties. External data were taken from Population estimates of Republic of Croatia 2015 released by the CBS." (Eurostat (2017).

    Coverage Adjustment Weight: Method

    "The aim of this adjustment was to improve the accuracy of data using socio-economical information available from the constantly updated
    Census 2011 and other surveys. Iterative raking scale methods were applied.[...].
    Calibration was carried out with a self made SAS program. Calibration was carried out in each rotational group. For the new rotational group the input weight for calibration is the one described previously. For the rest of rotational groups the input weight for calibration is previous year's final cross- sectional weight."

    Household

    Non-response Weight: Method

    Adjustment for non-response is carried out by multiplying a certain factor to provide an estimate of the inverse probability of response in the stratum.

    Coverage Adjustment Weight: Method

    The factor is weighted to adjust estimated distribution to the population distribution by Autonomous Community, age group and gender provided by the Demographic Projections Unit.

    "Within each design stratum, the non-response adjustment of the responding households is carried out by the inverse of the response rate, so as to “make up” for non-responding cases in that stratum." (Eurostat (2017). National Reference Metadata in ESS Standard for Quality Reports Structure (ESQRS), EL, p. 7.)

    Coverage Adjustment Weight: Method

    "Adjustment to external data involves the calibration of the household and personal weights in conjunction with external sources (Projections for population and household totals for the year 2016). This method enables the distribution of auxiliary variables, at household and individual level, to coincide with the corresponding population distribution of external data. The auxiliary variables used at household level are the household size, the tenure status and the Region (NUTS 2). Also, at personal level the auxiliary variables used are age groups (five years age groups) and gender. " (Eurostat (2017).

    Stratification Criteria

    "Strata contain socio-economic groups grouped by income class (12 strata in the new sample since sy2015, the earlier stratum 13 "no tax information" was combined with the stratum 11 "others, lower income class"). The register tax information on income type and amount for all members of the selected sample person's household-dwelling unit available at the time of sample selection (updated by the final population register data later) is used for creating strata for those who belong to target population (excl. overcoverage). The stratification normally takes the highest earning person as a categorising person for a stratum. As an exception to the rule is an entrepreneur who does not have to be the highest earning one for entrepreneurs strata. The income class division allocates the sample more to high-earners."

    "The household design weights (DB080, see below) were multiplied by nsample,h / nrespondents,h in every stratum h (inverse of the response probability in every stratum) in the survey year."(Eurostat (2017). National Reference Metadata in ESS Standard for Quality Reports Structure (ESQRS), FI, Annex 8, p. 1.)

    Coverage Adjustment Weight: Method

    "The calibration can be interpreted as integrative, i.e. both the household and person levels were included in the process. The levels and variables included in the calibration from total data, were as follows:
    1) Households: Region (≈NUTS-3) (%), type of municipality by degree of urbanisation (national classification) (%), household size (%), total sums of 15 different income variables
    2) Persons: sex and age classes (0-4, 5-9, ... , 80-84, 85- ) [...] Calibrations were performed by the logit method with the SAS supporting CALMAR macro." (Eurostat (2017). National Reference Metadata in ESS Standard for Quality Reports Structure (ESQRS), FI, Annex 8, p. 2.)
