|||
11.2. Quality management - assessment | |||
The quality of statistical surveys is evaluated by means of standard quality reports and quality indicators recommended in the ESS Handbook for Quality Reports as well as by self-assessment checklist and quality audits and reviews. Quality assessment of the monthly survey (DG-1), which is the data source for most STS indicators was conducted in 2022. A quality report was elaborated on the basis of standard quality procedures recommended in the ESS Handbook for Quality Reports. The quality of the monthly survey was described by means of standard quality indicators characterizing the following quality aspects: relevance, accuracy and reliability, timelines and punctuality, comparability and coherence. Relevance is maintained every year while drafting the "Statistical Survey Program of Official Statistics”. User satisfaction survey was conducted at the end of 2013. |
|
|||
12.1. Relevance - User Needs | |||
User needs are systematically monitored and taken into consideration while drafting the “Statistical Survey Program of Official Statistics” for the next year. The organs of the state power, government and self-government administration, organizations of employers and other institutions, provide opinions on statistical surveys and recommend implementation of the new ones.
|
|||

|||
13.2. Sampling error | |||
The Coefficient of Variation 5,4% for units employing 9 or less persons. For units employing 10 or more persons indicator is not applicable. There is an exhaustive survey for legal units employing 50 or more persons. Legal units employing:
|
|||
13.3. Non-sampling error | |||
There was negligible non-sampling errors concerning coverage, measurement and non-response. Improvement actions taken include increasing registry updates, careful logical and accounting controls and constant contact with the reporting units. The response rate for legal units employing 9 or less persons accounts for about 47.5 %. The response rate for units employing 10 or more persons is about 80.2%. |
|
|||
14.1. Timeliness | |||
The provisional index for trade is released within one month after the end of the reference month, however the final index (for Divisions: 45 and 47) is released within two months after the end of the quarter to which the reference month belongs. The index is transmitted to Eurostat according to Release Calendar. The monthly questionnaires concerning legal units employing 10 or more persons are filled by internet application until the 5th working day after the end of the reference month. The data collection is closed on the 9th working day after the end of the reference month. The quarterly questionnaires concerning units employing 9 or less persons are obliged to be delivered until the 15th working day after the end of the reference quarter. The data collection is closed on the 22nd working day after the end of the reference quarter. |
|||
14.2. Punctuality | |||
100% releases delivered on time according to the scheduled release dates. |
|
|||
15.1. Comparability - geographical | |||
The same statistical concepts and classifications are applied in the entire national territory. |
|||
15.2. Comparability - over time | |||
Data on net turnover (value of deflated) are comparable over time. When significant changes are introduced (e.g. change of classification, base year or methodology), historical time series are recalculated as far back as it is reasonably possible. Time series according to NACE Rev. 2 are available from 2000 onwards. |
|||
15.3. Coherence - cross domain | |||
The short-time statistics are compared with annual data (SBS) and administrative sources. |
|||
15.4. Coherence - internal | |||
Data are internally coherent. |
|
|||
Cost of the NSI – 16353 hours annually. |
|
|||
17.1. Data revision - policy | |||
Data revision policy (in Polish) is consistent with Eurostat recommendations (ESS guidelines on revision policy for PEEIs). According to these recommendations, notice about major revisions, e.g. in classification, methodology or base year, is provided in advance of the change. Notice about minor changes is given at the time the revision is introduced. The same revision policy is applied to data released nationally and transmitted to Eurostat. |
|||
17.2. Data revision - practice | |||
Every five years major revisions take places due to implementation of the new weights and the rebasing of the indices. Every year time series adjusted by working days and seasonal factors are updated. Quarterly revisions of data take places due to revision of data for small units. In 2018 time series from 2000 were recalculated for the base year 2015=100. Mean Revision (MR): 0.991 Mean Absolute Revision (MAR): 2.534 |
|
|||
18.1. Source data | |||
The source used is statistical survey based on the frame derived from Statistical Business Register (BJS). The sample of units employing 9 or less persons is randomly selected according to the employment strata of the units and the NACE Rev. 2 aggregates required in the STS Regulation. Legal units employing:
The sample is updated once a year. |
|||
18.2. Frequency of data collection | |||
Monthly data is collected for legal units employing 10 or more persons. Monthly data is also collected for small legal units (employing 9 or less persons), but only once a quarter. Collected data refer to the full reference period. |
|||
18.3. Data collection | |||
Two questionnaires are used: 1. DG-1 - the monthly report on economic activity (covers units employing 10 or more persons);
Data on net turnover are collected both for reporting month as well as for accrued period (cumulative data from January to the end of the reporting month). In accrued data, reporting units include possible revisions for the previous periods, which does not have an impact on the real level of the turnover value in reporting month. |
|||
18.4. Data validation | |||
Appropriate validation procedures are applied during the whole production process of statistics, and they are in line with rules provided by Eurostat, i.e. starting from selection of respondents to compiling indices and transmission to Eurostat. Data validation system incorporates many tools for data control, estimation and imputation, e.g. reports on data completeness and program procedures applied for error checking. The detailed completeness reports are essential tools in analysis of non-response as well as organizational and localization changes taking place in the reporting units. Data validation on the level of individual respondents is based on:
In the case of any doubts about data correctness there is a direct contact with an unit in order to explain outliers. Data validation on aggregated level is conducted both by the Regional Statistical Office responsible for the survey as well as by the authorial departments of Statistics Poland. The quality of aggregated data is monitored at least on three-digit level of NACE Rev.2 and on NUTS 2 level. Both the values and dynamics are compared with previous month and corresponding month of the previous year. Any discrepancies are scrutinized before dissemination of national indices. The most of STS indicators are surveyed on the same monthly questionnaire (DG-1) what means that validation procedures are quite consistent. |
|||
18.5. Data compilation | |||
Data concerning units employing 10 or more persons is estimated for non-response based on the units' responses for previous periods. This is done for units which submitted at least one questionnaire throughout the year. For units which have not submitted a questionnaire throughout the year the results for the responses are grossed up to the population taking into account employment and labour productivity. For the units in which the number of persons employed is 9 or less the non-responses are estimated using weights. The base weights are calculated separately for strata as ratios: the number of units of the frame population to the number of units in the sample. The base weights are corrected for unit non-response by multiplying the base weight by an adjustment factor. The survey results are produced by grossing-up the data from the sample to the population. The grossed up results are used only to compile indices at the level of the NACE Rev. 2 aggregates required in the STS Regulation. The indexes are calculated based on grossed up results. The index for a new reference period is calculated as a relation of its value to the average value of the base year. The indices of deflated turnover are calculated using the CPI, PPI and prices of agricultural products. |
