For Division 46 the survey covers units employing 10 or more persons (a representative sample for units employing 10-49 persons, a census is conducted for units employing 50 or more persons).
3.4. Statistical concepts and definitions
Net turnover is defined as the value of sold production, sales of merchanted goods (resale) and services supplied. It includes:
Net revenues from sale of products within the country and for export which have been manufactured or services supplied by the entity (goods, semi-finished goods and services) as well as packaging, equipment and external services if they are invoiced together with the purchased products;
Revenues from sale of goods and materials, i.e. current assets purchased for resale in a non-processed condition and products manufactured by the entity if they are sold by shops within the company’s network along with goods manufactured by other producers.
The following are excluded:
VAT invoiced to the client by the producer;
Taxes which fall on the products and services when they leave the factory (for example excise tax).
The monthly report on economic activity (concerning legal units employing 10 or more persons) covers among other variables the following information:
Turnover from sale of products (own goods and services);
Turnover from sale of goods and materials.

Documentation on procedures applied for quality management and assessment is available on the website: Quality in statistics.
11.1. Quality assurance
The legal basis of the quality measurement and assessment is the internal Regulation of the President of Statistics Poland No 35 of 28th December 2011, which came into force in the 4th quarter of 2012, and it applies for all statistics domains including STS. The quality assessment of statistical surveys was conducted according to an annual quality program for the official statistics which was in line with the Regulation of the President of Statistics Poland No. 35 of 28th December 2011.
Procedures and rules applied in quality assessment and monitoring are based on the ESS Quality Standards, i.e. the ESS Quality Declaration, recommendations of the ESS Leadership Expert Group on Quality (LEG) and the European Statistics Code of Practice (CoP).
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. In terms of accuracy and reliability there were a negligible non-sampling errors. Concerning timeliness and punctuality all releases are delivered on time immediately after they are prepared. Comparability of series is maintained geographically and over time. Coherence is observable with other cross domain surveys, quarterly and annually.
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. Data users, e.g. universities, research institutes, enterprises or individuals may indicate their needs by data inquiries and orders. Classification of national data users with an indication of their importance for official statistics, taking into account the purpose of data usage, is the following:
Key users – Eurostat, government and self-government administration, National Central Bank, Polish Financial Supervision Authority;
Important users – research institutes, universities, organizations of employers, enterprises, insurance institutions, media;
Other users – social organizations, professional self-government, economic self-government, trade unions, students, individuals.
12.2. Relevance - User Satisfaction
User satisfaction survey was conducted at the end of 2013. The survey covered the following data users: government and self-government administration, National Central Bank, Polish Financial Supervision Authority, research institutes, universities, organizations of employers, enterprises, insurance institutions, media, social organizations, professional self-government, economic self-government, trade unions, students, individuals.
User satisfaction survey was carried out via internet. For this purpose, an electronic questionnaire was elaborated and placed on Statistics Poland's server. Questions included in the questionnaire have been adjusted to all data users mentioned above and they comprised, among others, the following issues:
General information on using statistical data (which data were used, how often and for what purpose),
Assessment of data availability, transparency, timelines, comparability and level of details,
The completeness of data corresponds with requirements of the Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics, repealing 10 legal acts in the field of business statistics (EBS-Regulation).
Commission Implementing Regulation 2020/1197 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 mentioned above.
13.1. Accuracy - overall

Improvement actions taken include increasing registry updates, careful logical and accounting controls and constant contact with the reporting units.
13.2. Sampling error
The Coefficient of Variation 3.2% 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. 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 EBS Regulation. The sample of units employing 10-49 persons is selected for units at the NUTS 2 level and according to the NACE Rev. 2 aggregates required in the EBS Regulation.
13.3. Non-sampling error
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.
The response rate for legal units employing 9 or less persons accounts for 49.0%. The response rate for units employing 10 or more persons is 76.0%.
Actions are taken to speed up or increase the rate of response are telephone and e-mail follow-up.
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
Data are 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. Polish Classification of Activities (PKD 2007) is consistent with European Classification of Economic Activities (NACE Rev.2). Classification of territorial division applied in Polish statistics is consistent with the Nomenclature of Territorial Units for Statistics (NUTS).
15.2. Comparability - over time
Time series (according to NACE Rev. 2) are comparable over time from 2021 onwards.
15.3. Coherence - cross domain
Not applicable.
15.4. Coherence - internal
Data are internally coherent.
Cost of the NSI:
annual cost of collecting data on the DG-1 form – 128,800 hours (all variables included; the costs also cover part of national needs as it was not possible to separate the costs of data collection only for EBS purpose),
annual costs related to data processing, imputation, grossing up, validations, seasonal and calendar adjustment, as well as preparation of data for dissemination: 566 hours for net turnover in trade and 507 hours for volume of sale.
Burden of respondents:
average annual respondent burden for units employing 10 or more persons employed – 18 hours (time spent for preparing data and filling-in DG-1 form),
average annual respondent burden for units with 9 or less persons employed – 1 hour (time spent for preparing data and filling-in H-01/k form).
National needs are also included as it was not possible to separate the response burden only for EBS purposes.
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
Quarterly revisions of data take places due to revision of data for small units. 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.
Mean Revision (MR): 0.157
Mean Absolute Revision (MAR): 1.460
18.1. Source data
The statistical survey based on the frame derived from Statistical Business Register (BJS). Data is collected for legal units, however in the further process they are recalculated for the kind of activity units.
For the legal units employing 50 or more persons the survey is exhaustive. Sample is used for units employing 10-49 persons and for G45 and G47 also units employing 9 or less persons.
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 EBS Regulation. 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 (in December 2024):
50 or more persons are included in an exhaustive survey (3767 units were covered with the survey, out of which, 3327 units submitted report i.e. 88.3%);
10-49 persons are observed by a minimum 10% sample survey (in 2024, out of 4388 units from this group, 2873 submitted report, i.e. 65.5%).
9 or less persons are observed quarterly in G45 and G47 by a 2.0% sample survey (10000 units were covered with the survey, out of which4898 submitted report, i.e. 49.0%).
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);
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 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.
2. H-01/k – quarterly inquiry of trade units (covers units in which the number of persons employed is 9 or less). All data collection is done 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 quarter; 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 quarter.
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. 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. 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 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 EBS Regulation.
The indices 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 volume of sales are calculated using the CPI, PPI and prices of agricultural products.
Weights based on added value are used to calculate aggregates for volume of sales.
regARIMA, 1 or 6 regressors connected with the changing number of working days in a week resulting from country specific national holidays (the number of regressors depends on statistical testing and quality of model verification),
all moving holidays present in the national calendar are included,
leap year effect (if relevant – depends on statistical significance and compliance with economic theory of the estimated value),
Easter effect (if relevant – depends on statistical significance and compliance with economic theory of the estimated value),
outliers (AO, LS, TC) with automatic detection supported by additional analysis and a priori knowledge,
default critical value for automatic outlier detection (3.5).
Seasonal adjustment:
automatic model selection with additional non-automatic verification of problematic cases,
additive or multiplicative decomposition (depends on the series and results of statistical testing, sometimes manually revised considering SA series behaviour – ex. annual totals coherence),
filter length not applicable (TRAMO/SEATS method),
no a priori identified breaks in the series,
direct adjustment of all series,
the consistency of separately adjusted components and aggregates (a direct approach) is assured by manual checking/controlling of models used and SA series behaviour for series related by important dependencies
Revisions:
model updated once a year including revision of historical data,
for G45 and G47 revised monthly data is presented after 2 months from the end of each reporting quarter.
Not applicable.
The net turnover index measures changes in the value of revenues from sale of products, goods and materials in monthly periods with reference to the base period.
The volume of sales index is a deflated turnover using price index (CPI, PPI and prices of agricultural products).
The indices belong to short-term indicators, which describe the current economic situation. They are used as a basis for economic policy decisions.
