Not applicable.
15.4. Coherence - internal
Not applicable.
Cost of the NSI:
128,800 hours – annual cost of collecting data on the DG-1 form (all variables collected via DG-1 are included). The costs cover also national needs (it was not possible to separate the costs of data collection only for EBS purposes)
776 hours – annual costs related to data processing, imputation, grossing up, validations, seasonal and calendar adjustment, as well as preparation of data for dissemination (it concerns only cost for net turnover in services)
Burden of respondents: 18 hours – average annual respondent burden (it covers data preparation and filling-in the DG-1 form), also national needs are included as it was not possible to separate the response burden only for EBS purposes.
17.1. Data revision - policy
Data revision policy 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 are updated. In case of detecting errors in published data they are corrected as soon as possible.
In 2024 time series from 2021 were recalculated for the base year 2021=100
18.1. Source data
The statistical survey based on the frame derived from Statistical Business Register (BJS) is used as a data source. Data are collected for legal units, however in the further process they are recalculated for kind of activity units.
For legal units employing 50 or more persons the survey is exhaustive. A 10% sample is used for units employing 10-49 persons.
The sample of legal units employing 10-49 persons is selected at the NUTS 2 level and according to the NACE Rev. 2 aggregates required in the EBS Regulation.
Legal units employing:
50 or more persons – a census is conducted (in 2024, 5441 units were covered with the survey, out of which, 4599 units submitted report i.e. 84.5 %),
10-49 persons employed – a minimum 10% sample is selected (in 2024, out of 3668 units from this group, 2182 submitted report, i.e. 59.5%).
The samples is updated once a year.
18.2. Frequency of data collection
Monthly data are collected for legal units employing 10 or more persons. Collected data refer to the full reference period.
18.3. Data collection
The DG-1 questionnaire – monthly report on economic activity – is used. It covers legal units employing 10 or more persons.
The questionnaire covers, among others, the following information:
Revenues from sale of own products (goods, services) – of which non-domestic (of which euro-area);
Value of manufactured products not categorized as sale, but included in sales;
Revenues from sale of merchanted goods (resale) – of which non-domestic (of which euro-area);
Persons employed;
Average paid employment;
Gross wages and salaries;
Retail sale and wholesale;
Excise tax;
Product subsidies received;
New orders – of which non-domestic (of which euro-area).
Data on services 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.
All data is collected by electronic questionnaire (sporadically by postal questionnaire) or by CATI. Dissemination of electronic questionnaire in the Reporting Portal for reporting units — until the 5th working day after the end of the reference month; reminding the reporting units over the phone or e-mail that they have not completed the questionnaire — on the 6th working day after the end of the reference 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.
Validation procedures are applied on the level of individual respondents and on aggregated level as well as before data transmission to Eurostat. Data validation on the level of individual respondents is based on:
Special program procedures used for errors checking when data are inserted to the system (logical -computing control) – these procedures help to avoid errors at the stage of data collection what is essential for final data results.
Information given by an unit on the reasons of substantial difference in the level of data reported in the current period as compared to the equivalent data for the previous period (e.g. cancellation of all previously-issued invoices, correction of invoices, reducing/increasing the number of orders, employee dismissals).
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 and other Regional Statistical Offices. 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. After data acceptance by all units data gathered by legal units are recalculated into kind of activity units. In the next step all engaged Statistics Poland units verify and validate received data. Validation procedures are also performed before data transmission to Eurostat. The structured data files in SDMX format are created and data assigned to the codes are checked in detail. In case of significant data revisions, for example when the base year changes, the whole time series are submitted to validation procedure.
The most of Short term business statistics 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 are 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 also 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.
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 EBS 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 base weights for units employing 10–49 persons are calculated taking into account the employment and labour productivity.
18.6. Adjustment
Level of detail: total, 2-digit level.
Software: JDemetra+, TRAMO/SEATS method.
Pre-adjustment:
regARIMA, 6 regressors connected with the changing number of working days in a week resulting from national holidays,

There were 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.
Index.
Data concerning units employing 10 or more persons are 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 also 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.
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 EBS 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 base weights for units employing 10–49 persons are calculated taking into account the employment and labour productivity.
The statistical survey based on the frame derived from Statistical Business Register (BJS) is used as a data source. Data are collected for legal units, however in the further process they are recalculated for kind of activity units.
For legal units employing 50 or more persons the survey is exhaustive. A 10% sample is used for units employing 10-49 persons.
