Annexes:
Methodology
10.7. Quality management - documentation

Audit reports including all the test and analysis carried out within the audit are stored and the public parts are available on request (see also quality management).


11. Quality management Top
11.1. Quality assurance

1. Irregular methodological audits. Audits are usually carried out by expert group comprising of internal and external experts (NA experts, representatives of universities, ministries etc.).
2. Important aspects and procedures of quality management within statistical production process are documented in the so-called technical projects, event. instructions for surveyors that are available for every statistics produced.

11.2. Quality management - assessment

1. Standard STS compliance assessments carried out by Eurostat.
2. The methdological audit (see also Quality assurance) includes inter alia different quality analysis, e.g. benchmark analysis, response analysis, in case od leading indicators, their abilty to predict the changes in the economy.
3. Regular response rate measurement.
4. Regular confrontation of estimates with later available administrative data or comparable data acquired or estimated from statistics with different periodicity.


12. Relevance Top
12.1. Relevance - User Needs

1. External users: Eurostat, OECD, Ministry of Industry and Trade, Czech National Bank, professional associations, media, general public.
2. Internal users: Quarterly National Accounts Department.
The CZSO primarily tries to fulfill its commitments towards the European Commission, however, generally we try to deal with the requirements of all users equally.

12.2. Relevance - User Satisfaction

No users satisfaction surveys are carried out, however, we are constantly in contact with different groups of users, e.g. ministries, Czech National Bank, different associations (e.g. Association of small and medium sized Enterprises and Crafts of the Czech Republic), internet users etc.

12.3. Completeness

The Czech Republic provides Eurostat with all data required by the STS Regulation.


13. Accuracy Top
13.1. Accuracy - overall

Overall asessment:
- Sampling errors are not systematically measured. The appropriate system for gathering such infomation is under costruction (see 13.2).
- Response rate is reasonable.
- The main problem is the high misclassification mainly in the smallest units.

13.2. Sampling error

Sampling error is not regularly measured. It is foreseen to be a standard compoment of the SMS Quality system, which is currently being developed.

13.3. Non-sampling error

The main problems related to non-sampling errors athe the following:
1. Administrative data available for the smallest units in the frame (i.e. natural persons and legal persons without employees, which are not VAT payers) are outdated at the moment when the sample is drawn (data refers to R-1 rather than R). No other data source for activity assessment is available.
2. Relatively high degree of misclassification particularly of small units (natural persons and legal persons without employees, which are not VAT payers). The details are available in the SBS Quality report.
3. Non-response. However, it is not regarded as serious problem.
4. Organisational changes (mergers, splits, births and deaths) in reporting units and in the population as a whole during the year.  The BR is relatively slow, what increases an importance of feedback from infraannual surveys.

The response rate is approx. 85 % at the time when the survey is closed for a reference quarter


14. Timeliness and punctuality Top
14.1. Timeliness

Data are sent to Eurostat 2 months and 15 days after the end of the reference quarter (number of persons employed) and 3 months after the end of the reference quarter (gross wages and salaries, hours worked). Data are not published nationally.

Number of persons employed and hours worked are not published nationally.

Average registered number of employees (headcount) and wages, excl. other personnel expenses are published nationally according to the published deadlines (approximately 90 days after the end of the reference quarter).

14.2. Punctuality

Releases delivered on time: 100 %


15. Coherence and comparability Top
15.1. Comparability - geographical

There are a few specifities of the Czech labour market that could lead to minor discrepancies when the comparability of data between countries is concerned, namely:
1. Quite a high number of own-account workers (approximately 975 thousand, 2015 compared to the whole population of the Czech Republic (10,5 million, 2015).
2. Quite a high number of people work as an employee and partly as own-account worker.
3. The quality of the respective indicators are influenced by the shortage of data. Our estimates are based particularly on the administrative (they are available quarterly, but only for emploeyees) and LFC data.

15.2. Comparability - over time

The relevant time series are available from the first quarter of 2000, they are comparable over time.

15.3. Coherence - cross domain

As basically all labour market data surveyed among businesses are based on the same administrative sources and the same estimation methods, methodological coherence especially between quarterly (STS) and annual (SBS) outputs is secured. The regular coherence checks are taken for granted.

15.4. Coherence - internal

There are no problems regarding internal consistence of the time series in question.


16. Cost and Burden Top

Average quarterly number of employees and quarterly wages are surveyed quarterly. They are a part of the questionnaire P 3-04. The questionnaire is completed by the sample of approximately 470 retail businesses. We do not follow neither cost of individual indicators nor cost of CSO.


17. Data revision Top
17.1. Data revision - policy

The system of regular revisions is briefly described on the CZSO website.

Methodological changes are announced at the time of the change, major changes in advance.

Revision calendar is published on the CZSO website.

The same revision policy is applied to data released nationally and transmitted to Eurostat.

Key Documents
Revision Policy of the CZSO
17.2. Data revision - practice

We distinguish regular/planned and irregular/unplanned revisions. The regular revisions are carried out every quarter, irregular revision are undertaken in case of unpredictable significant events (e.g. a significant respondent corrected data, correction/update of administrative data etc.). After first release, data are usually not changed more than 1 %.


18. Statistical processing Top
18.1. Source data

Sources: Statistical survey (P3-04) and administrative data

1) Type of source: Statistical survey (P3-04)

Frame on which the source is based: Business Register (RES)

Sample or census: Stratified sample.

Criteria for stratification: Stratified sample with exhaustive strata. Number of employees, activity (NACE 2-digit level), turnover.

Only enterprises with 20 and more employees are covered by the quarterly survey (For the size class 20-49 employees 30% of units are sampled). Strata with 50 and more employees are exhaustive. The questionnaire is completed by the sample of approximately 470 retail businesses.

Frequency of updating the sample: The sample is updated quarterly.

2) Type of source: administrative data

Besides the data acquired and estimated through the P 3-04 survey, SBS survey and LFS, administrative data on the number of insurance policy holders and the basis of social security insurance assesment are used for the estimation of the indicators in question.

18.2. Frequency of data collection

1. Surveyed data are collected quarterly.
2. Administrative data are available 2 months after the end of reference period.

18.3. Data collection

Questionnaire P 3-04 is a quarterly questionnaire for units in selected activities.

Data are collected by electronic, web and postal questionnaires. Non-responding units are contacted by mail, e-mail or phone and can be sanctioned.

18.4. Data validation

The electronic form of questionnaire contains built-in logical controls that draw respondent's attention to possible errors. Moreover, after receiving, data collected via electronic form of the questionnaire are further validated by statisticians.
Data obtained via the postal form of the questionnaire are entered to the database using specific software (DANTE) with built-in logical controls. When the DANTE software indicates a possible error, the statistician entering data to the database contacts the respondent with the aim to correct/validate data.

18.5. Data compilation

1. Number of employees and gross wages and salaries for enterprises with 20 and more employees are estimated using data collected via quarterly surveys and available administrative data (see also source data).  
2. Units in the surveyed part of the population (units with 20 and more employees) are divided into stratas.
3. Data for each individual nonresponse unit and unit not included in the sample and belonging to the surveyed part of the population are estimated.
4. If a unit submitted the questionnaire/questionnaires for the same quarter of the last year, the number of employees and gross wages are estimated using the submitted data and average y-o-y development of the respective variables in the stratum in which the unit in question belongs.
5.  If a unit submitted only the questionnaire/questionnaires for the last quarter, the number of employees and gross wages are estimated using the submitted data and average q-o-q development of the respective variables in the stratum in which the unit in question belongs.
6. Otherwise the data are estimated using available administrative data.
7.  Number of employees and gross wages and salaries for the non-surveyed part of the population (units with less than 20 employees) as well as the hours worked and the number of own-account workers (working proprietors and unpaid family workers for whom work for the unit is their main activity)  for all the units in the population are estimated using avaliable administrative data, the latest SBS data and development of LFS data.

18.6. Adjustment

Seasonal and working day adjustment is performed on the following series using JDemetra+ software (TRAMO-SEATS method):

NACE Divisions - G47

For details on seasonal and working day adjustment please see the annex, which refers to the situation as of 2017.
