N/A.

Work in progress on setting up on new site of the Statistical Office of the Republic of Serbia.

A detailed control of the results is carried out before the results of the survey are published. Based on the Customer Satisfaction Survey, feedback was received on the quality and comprehensibility of published results.

The Methodological Manual provides guidelines and standards for the implementation of the surveys in the Member States. It is updated every year according to the changed contents of the model questionnaires.

Before publishing the results, detailed control is carried out by examining the results obtained. Through two user satisfaction surveys, feedback was obtained on the quality and comprehensibility of the published results of all surveys in the SORS, and included subject research.

RATEL, Government institutions, public sector.

User reviews and opinions were obtained through the Customer Satisfaction Survey 2013, 2015, and 2017.

 (Quality report)

A) Reliability of breakdowns to be used for the calculation of European aggregates

Please indicate for both the general survey and for micro-enterprises the breakdowns to be used for the calculation of European aggregates that have a sufficiently high quality to be released at national level by introducing an "x" in the column next to the Y/N responses.

Note: In the case there is a grant agreement that foresees that certain breakdowns will be provided with sufficiently high quality to allow their release at national level, the following table should reflect the grant agreement ("x" next to "Yes" for the respective breakdowns).

In the case data for few variables/breakdowns cannot be released - although the particular breakdowns had been taken into account in the sampling design as foreseen in the grant agreement - it is expected that the breakdowns are marked with "Yes", data are accordingly flagged as unreliable and explanations should be provided in point 6.1. (B) (below)

In all cases, data will be evaluated for completeness and compliance with the terms in the grant agreement (if applicable) and the current quality report; additional clarifications may be requested.

(Quality report)

B) Comments on reliability and representativeness of results and completeness of dataset

These comments should reflect standard errors reported for the indicators and breakdowns in section 6.2.1 (Sampling error - indicators) and the breakdowns for European aggregates, as well as other accuracy measurements. The estimated standard error should not exceed 2pp for the overall proportions and should not exceed 5pp for the proportions related to the different subgroups of the population (for those NACE aggregates for the calculation and dissemination of national aggregates). If problems were found, these could have implications for future surveys (e.g. need to improve sampling design, to increase sample sizes, to increase the response rates etc.).

[1] Please note that if data were not flagged as unreliable they will be released

Calculation of the standard error

Various methods can be used for the calculation of the standard error for an estimated proportion. The aim is to incorporate into the standard error the sampling variability but also variability due to unit non-response, item non-response (imputation), calibration etc. In case of census / take-all strata, the aim is to calculate the standard errors comprising the variability due to unit non-response and item non-response.

Please, describe below the approach which you have followed. This information will help Eurostat to evaluate the comparability of the standard errors supplied in the previous section by the different statistical institutes participating in the survey.

Please fill in the sub-concepts below.

The survey is being conducted in March, while the research results are published at the end of the third week of September.

All data are sent to Eurostat in time.

N/A.

Time series 2009-2018. 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

Survey is conducted on two-stage strtified random sample. Gross sample size is 1781 household, response rate is 84.7%, or 1509 enterprises. Statistical data source.

Annual survey.

 The survey is conducted through a telephone survey, (CATI) method of data collection on IST. The questionnaire was formulated according to the Eurostat methodology, where it was previously tested and accepted by all member states and candidates. The interviewer training is conducted according to the instructions for using the data entry program in IST.

We use EUROSTAT validation program.
