1-st level – 21 sections identified by alphanumerical codes (A)
2-nd level – 88 divisions identified by two-digit codes (99)
3-rd level – 272 groups identified by three-digit codes (99.9)
4-th level- 615 classes identified by four-digit codes (99.99)
5-th level – 654 subclasses identified by a five-digit alphanumerical code (99.99. A) – the national level introduced in order to select kinds of activities characteristic of the Polish economy and being the subject of statistical observation.
2 (b)Please provide examples of the coding system used at each level.Section A Agriculture, forestry, hunting and fishing
Division 01 Crop and animal production, hunting and related service activities
Group 01.4 Animal production
Class 01.41 Raising of dairy cattle
Subclass 01. 41.Z Raising of dairy cattle

Or e.g.:
Section H Transport and storage
Division 49 Land transport and transport via pipelines
Group 49.5 Transport via pipeline
Class 49.50 Transport via pipeline

49.50.B Transport of other commodities via pipelines

 
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.The PKD is a classification of kinds of economic activities elaborated on the basis of the Statistical Classification of Economic Activities in the European Community, Rev. 2 (NACE), with the maintenance of a close relationship between those classifications.
Despite that the PKD is a more detailed classification than NACE, additionally created detailed groupings can always be aggregated into a NACE categories, within the framework of the same structure.
If at the national level no additional division in relation to the international level have been introduced (class equals subclass), such a subclass is identified by letter Z.
Related classifications:
1) The Classification of Goods and Services (PKWiU)
2) The PRODCOM List used in the surveys on industrial production
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)The PKD maintains full coherence and comparability with the NACE Rev.2. in terms of its methodology, concepts, scope and coding at the 4-digit level (section, division, group, class)
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.There are no deviations from NACE, Rev.2.
3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)Data is reported in accordance with the needs of international organizations.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.National classification is linked to international classifications.
 
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.The PKD is used for the following statistical purposes:
1. Registers of economic entities,
2. National and regional accounts,
3. Structural businesses statistics
4. Short –term statistics
5. Statistics of labour market
6. Statistics concerning transport, energy and waste
7. Statistics concerning the protection of environment

Data collecting and publishing according to the PKD takes place at different classification levels, e.g.:
- data concerning labour force, wages and salaries, investment inputs, gross value of fixed assets, gross value added – section level,
- data concerning the protection of environment – national level,
- at the subclass level in surveys of: dwelling stocks, costs of maintenance of stocks of premises, waterworks and sewage system and the disposal and remediation of municipal waste,
- at the 4-digit level the classification is used in the surveys on service producer’s prices, transport services prices, storage and telecommunications. In the publication of the survey on service producer’s prices the PKD is used at the division and group levels and in the publication of transport services prices, storage and telecommunications at the level of section, division, group and class,
- at the level of classes it is also used for the selection of units for the survey concerning the evaluation of enterprises providing services related to the service of economic activities. Data is published on aggregated levels, different from the level of data collection, with the exception of activities embraced by statistical secrecy,
- according to the kinds of activity there are also provided surveys in the scope of short-term statistics (monthly and quarterly data) concerning retail and wholesale trade and turnovers in retail trade. The elaborated information is published on the level of group, class or groupings, created for selected PKD classes,
- PKD is used for the collection and analysis of data, then its dissemination. In enterprise surveys (for example on employment, wages and salaries) general information is collected by the class and subclass levels; data is published at the level of sections and divisions. However, in representative surveys (for example, structure of earnings, job vacancy survey and labour force survey-LFS ) information is collected variously, depending on the specific surveys; data from these surveys are published at the level of sections.

4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)Public administration organs use classifications in various legal regulations and information systems (e.g. the National Register of Taxpayers, the National Court Register). The Ministry of Finances makes use of the PKD in a budget classification.
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?Each institution can create registers, lists or indexes for their own needs on the basis of classification standards.
Statistical offices use national standards or the ones directly introduced by the European Commission/Council of the European Communities or the Statistical Commission of the United Nations Organization.
