3.1. Data description | |||
Maritime transport data refer to gross weight of goods (in tonnes), passenger movements (in number of passengers) as well as for vessel traffic (in number of vessels and in gross tonnage of vessels). |
|||
3.2. Classification system | |||
The following classifications are applicable: Maritime Coastal area: the nomenclature is based on the Geonomenclature (the country nomenclature for the external trade statistics of the Community and statistics of trade between Member States, originally drawn up by the Council Regulation (EEC) N°1736/75) in force in the year to which the data refer (RAMON: https://showvoc.op.europa.eu/#/datasets/ESTAT_Geonomenclature_2021_%28GEONOM_2021%29/data). Ports: the codes used are the official UN/LOCODEs, when they exist. If a port does not have an official UN/LOCODE a provisional (numeric) code is attributed to the port. As soon as an official UN/LOCODE is attributed by the United Nations Economic Commission for Europe (UNECE) to the port at the request of the competent national authority, the provisional (numeric) code is replaced by the final official one. In exceptional cases (see for example one-port transport or special aggregation for minor ports) permanent numeric codes are attributed to special locations or activities. The code list of UN/LOCODE is available by country through the following link: http://www.unece.org/cefact/locode/service/location.html. According to the relevant directive, Eurostat draws up a list of ports, coded and classified according to countries and maritime coastal areas. The list of ports is included in implementing legal acts and as such is published in the Official Journal of the European Union (the "official" list). The most recent list of ports published in the Official Journal is found in Commission Decision (EU) 2018/1007 Nationality of registration of vessels: the nomenclature used is the Geo-nomenclature (the country nomenclature for the external trade statistics of the Community and statistics of trade between Member States, originally drawn up by the Council Regulation (EEC) N°1736/75) in force in the year to which the data refer (RAMON: https://showvoc.op.europa.eu/#/datasets/ESTAT_Geonomenclature_2021_%28GEONOM_2021%29/data). The type of ship classification is harmonised with an internationally agreed International Classification of Ship by Type (ICST). The type of cargo classification, available in Directive 2009/42/EC, has been established in conformity with the United Nation ECE Recommendation N°21. |

|||
3.4. Statistical concepts and definitions | |||
Main concepts used in this domain are the following and for more information on the concepts and methodology, please consult the Reference Manual on Maritime Transport Statistics.
Port -A place having facilities for merchant ships to moor and to load and/or unload cargo or to disembark and/or embark passengers to or from vessels, usually directly to a pier.
Bunkers and stores supplied to vessels shall be excluded from the scope. Seagoing vessel -Floating marine structure with one or more surface displacement hulls. In the context of the Directive, sea-going vessels are vessels other than those which navigate exclusively in inland waters or in waters within, or closely adjacent to, sheltered waters or areas where port regulations apply. Swap bodies are excluded. Although without internal volume flats used in maritime transport should be considered to be a special type of container and therefore are included here. For a fuller description, reference should be made to ISO 668 and 1496.The related term "container cargo" refers to containers, with or without cargo, which are lifted on or off the vessels which carry them by sea. Ro-Ro unit- This means wheeled equipment for carrying cargo, such as a truck, trailer or semi-trailer, which can be driven or towed onto a vessel. Port or ships' trailers are included in this definition. Classifications should follow United Nations ECE Recommendation No 21 'Codes for types of cargo, packages and packaging materials'. Live animals on the hoof are included. Vehicles being transported as cargo as opposed to a means of transport for freight are recorded in the separate headings of the Ro-Ro cargo classification, when they are rolled on or rolled off a vessel on their own wheels.

11.1. Quality assurance | |||
The quality of statistical information and its production process is ensured by the provisions of the European Statistics Code of Practice and ESS Quality Assurance Framework. In 2007, a quality management system, conforming to the requirements of the international quality management system standard ISO 9001, was introduced at Statistics Lithuania. The main trends in activity of Statistics Lithuania aimed at quality management and continuous development in the institution are established in the Quality Policy. Monitoring of the quality indicators of statistical processes and their results and self-evaluation of statistical survey managers is regularly carried out in order to identify the areas which need improvement and to promptly eliminate the shortcomings. |
|||
11.2. Quality management - assessment | |||
Data quality is in line with the accuracy, timeliness and punctuality, comparability and compatibility requirements. Before presenting survey results to users, the quality of the information obtained is analysed. Additional statistical quality checks are performed. The aggregated results are compared with the results of the previous period and the same period of the past year. Tendencies of vessels, goods and passenger traffic at the seaports in time series are analysed. When quality issues are encountered, the data providers are contacted and asked to investigate the problems. The data provider corrects statistical data and, if needed, sends back the corrections or new revised datasets. |
|
|||
12.1. Relevance - User Needs | |||
The main users of statistical information are State and municipal authorities and agencies, international organisations, the media, research and business communities, students, whose needs are satisfied without a breach of the confidentiality principle. |
|||
12.2. Relevance - User Satisfaction | |||
From 2005, user opinion surveys have been conducted on a regular basis. Official Statistics Portal traffic is monitored, website visitor opinion polls, general opinion poll on the products and services of Statistics Lithuania, target user group opinion polls and other surveys are conducted. In 2007, the compilation of a user satisfaction index was launched. The said surveys are aimed at the assessment of the overall demand for and necessity of statistical information in general and specific statistical indicators in particular. More information on user surveys and their results is available in section User surveys on the Statistics Lithuania website. |

A special program is used for statistical data entry, which searches for errors at the time of entry. The requirements for the validation of statistical data are provided in the technical task of the programming work for the statistical survey. Data validation takes place at the time when data is integrated into the statistical database. The formats, the codes and missing values of statistical data are checked. When uncorrectable errors or missing values are detected, the respondents are contacted. To ensure the quality of the statistical data, additional checks of the primary database are performed. The completeness and reliability of integrated data is checked, the relation between indicators is analysed. |
|||
