3.1. Data description | |||
Data collection at EU level is based on the legal act Regulation EU 2018/643 and covers goods and passenger transport by rail.
Data in the annexes are broken down by different categories, e.g. in annex A: by type of transport (total, national, international - total, outgoing, incoming, transit), by type of goods, by category of dangerous goods, etc. See for details: part 1 of the Reference Manual on Rail Transport Statistics Data on passenger or goods transport cover national and international transport performed by Polish railway undertakings. |
|||
3.2. Classification system | |||
Statistics on goods transport by railway apply the following statistical classifications:
- until reference year 2007 (including), 24 groups of goods defined by NST/R according to the Regulation (EC) No. 91/2003; - from reference year 2008 onwards (see: Glossary - NST 2007), 20 divisions of goods following the 'Standard Goods Classification for Transport Statistics 2007’;
- until reference year 2018 (including), 9 groups of dangerous goods by RID according to the Regulation (EC) No. 91/2003; - from reference year 2019 onwards, 9 groups of dangerous goods by RID according to Regulation (EU) 2018/643;
according to European legislation: "NUTS Nomenclature of territorial units for statistics" (see also RAMON/NUTS). The NUTS2 classification which is in force at the time when data collection takes place is used, and ISO-3166 alpha-2 for the rest countries (e.g. for the countries/regions outside EAA). In regional statistics, if NUTS2 region is unknown, ISO-3166 alpha-2 code followed by XX is used. If the place is completely unknown (i.e. unknown country), the code XXXX is used.
|
|||
3.3. Coverage - sector | |||
Railway sector:
entities of the national economy or national bodies responsible, in particular, for establishing, managing and maintaining railway infrastructure, including traffic management and control-command and signalling. The entities managing solely sidings are excluded;
entities of the national economy licensed to transport by the Polish Office of Rail Transport. Included are all transport operators that dispose of/provide traction. Excluded are railway transport operators which operate entirely or mainly within industrial and similar installations, including harbours, and railway transport operators which mainly provide local tourist services, such as preserved historical steam railways. Undertakings whose only business is to provide services for the transport of passengers by metro, tram and/or light rail are excluded;
railway undertakings also being rail infrastructure managers.

|||
10.7. Quality management - documentation | |||
There are national procedures applied for quality management, e.g. annual quality analysis (quality report; not available for the public).
|
|
|||
11.1. Quality assurance | |||
There are procedures in place to plan, monitor and improve the quality of the statistical processes. To improve the quality, the data are collected via IT tool equipped with internal consistency and counting checks preventing from delivering inconsistent information within a questionnaire. The questionnaires include guidelines which are improved systematically if needed (on the basis of the feedback given by respondents). There are additional checks made by the CSO staff, the data providers are asked to explain or/and revise the figures if needed. The datasets are systematically validated by Eurostat. Check results are analysed and the data are corrected if needed, or explanations are given in the country specific notes. There are several rules that the CSO applies when conducting statistical surveys:
|
|||
11.2. Quality management - assessment | |||
Data quality can be assessed as high. However, in case of goods transport one should note that:
Regarding the inconsistency between the methodology of dataset A and the one presented in the Reference Manual, the CSO is going to standardise the dataset A collection in the coming years in accordance with the Reference Manual. |
|
|||
12.1. Relevance - User Needs | |||
The purpose of the data collection is to provide information on the level and structure of transport services and on the transport potential for shaping economic policy as well as transport market analysis and research. Data are collected for national and European strategies and programs, e.g.:

|
|||
12.2. Relevance - User Satisfaction | |||
Not applicable - opinions are not collected |
|||
12.3. Completeness | |||
The data collection on rail transport statistics follows the provisions of the Regulation 2018/643. All variables in all data sets are provided. However, in case of goods transport one should note that:
|
|
|||
13.1. Accuracy - overall | |||
Overall accuracy of the railway transport of passengers and goods statistics is good. |
|||
13.2. Sampling error | |||
Not applicable |
|||
13.3. Non-sampling error | |||
The population is composed of the entities of the national economy (rail sector). The undertakings offering rail transport services on the territory of Poland which are not registered in Poland, do not take part in the surveys. The CSO monitors their share in the Polish rail market taking into account the data available on the Polish Office of Rail Transport website. So far their share can be considered negligible (e.g. regarding passenger rail transport, it is less than 0.5%). Within the population, the response rate can be assessed as high (close to 100%). The respondents hardly ever deliver incomplete questionnaires. If a variable is not delivered by a respondent, it is estimated on the basis of information available (other sources). To reduce different types of errors, the following actions are undertaken: - IT tool consistency and counting checks are systematically analysed and improved, - guidelines are improved, - the data providers are contacted and asked for completion / explanation / corrections if needed.
|
|
|||
14.1. Timeliness | |||
Data are provided to Eurostat:
|
|||
14.2. Punctuality | |||
Datasets are usually transmitted on time. |
|
|||
15.1. Comparability - geographical | |||
Some non-comparability in rail goods transport may follow from adopting a slightly different metodology than the one described in the Reference Manual on Rail Transport Statistics. See: point 11.2. |
|||
15.2. Comparability - over time | |||
As from 2004 the statistics on the railway transport are comparable over time. Time series checks are regularly made to detect inconsistencies in the data. There were no time series breaks.
|
|||
15.3. Coherence - cross domain | |||
The data are compared with other sources for operational reasons. However, the analysis of coherence with other sources is not usually made. |
|||
15.4. Coherence - internal | |||
Statistics are consistent within a given data set.
|
|
|||
Cost of production of a railway transport statistics is estimated and presented in Statistical Survey Program of Official Statistics (Program Badań Statystycznych Statystyki Publicznej; see for details: PBSSP) The average time of data collection by a respondent – 120 min. The average time for completion of a questionnaire by a respondent – 30 min.
|
|
|||
17.1. Data revision - policy | |||
Respondents are asked to verify data on a regular basis during the survey or checks. If some errors are detected after the time of data publication, they are corrected in on-line databases (or in following publications - if possible) as soon as possible. Systematic data revisions are not made. |
|||
17.2. Data revision - practice | |||
See: point 17.1. |
|
|||
18.1. Source data | |||
Datasets are based on surveys (full). Administrative data sources are used additionally for population determination only (e.g. licensed rail transport undertakings) |
|||
18.2. Frequency of data collection | |||
Data is collected quarterly and annually. |
|||
18.3. Data collection | |||
Reporting units submit data on-line via IT system - Reporting Portal. In exceptional cases other ways (email, postal service) of data delivery is acceptable (the data are transferred into the system by the CSO staff). The questionnaires available in the IT system are improved and tested every year before the beginning of the survey. The on-line questionnaire is equipped with internal consistency and counting checks preventing from delivering inconsistent information within the questionnaire. The system authomatically generates notifications about deadlines, the notifications are delivered to respondents via email. The CSO staff monitors the progress of completing the questionnaires in the IT system. If there is no reply from a respondent despite of notifications, the CSO staff makes contact with them by phone. |
|||
18.4. Data validation | |||
National level:
Eurostat level: Since 1999, micro-data from the reporting countries are submitted according to Commission Regulation 2018/643. The data are then checked and validated by EUROSTAT. Detected errors are then reported back to the data providers with the request for correction, this is an iterative process until at least 99.5% of all data records validated and loaded in the database. |
|||
18.5. Data compilation | |||
The datasets are delivered to Eurostat after verification and aggregation. |
|||
18.6. Adjustment | |||
