Statistical Terms Glossary

Fraction of the biomass that is caught by unit of fishing effort.; The relationship between the catch rate (CpUE) and the true population size (B). Thus, the unit of catchability is fish caught per fish available per effort unit and per time unit.

Water collected on a catchment area, such as a basin or reservoir.

The quantity of fish caught (in number or in weight) with one standard unit of fishing effort; e.g. number of fish taken per 1000 hooks per day or weight of fish, in tons, taken per hour of trawling. CPUE is often considered an index of fish biomass (or abundance). Sometimes referred to as catch rate.

Goods in transport may be classified according to type.

The categories of goods carried by rail are those defined by the NST/R nomenclature (Standard Goods Nomenclature for Transport Statistics/revised - EUROSTAT) or CSTE nomenclature (Commodity Classification for Transport Statistics in Europe - UN/ECE).

The categories of goods carried by sea are those defined by the NST/R (Standard Goods Nomenclature for Transport Statistics/revised - EUROSTAT) or CSTE (UN-ECE Commodity Classification for Transport Statistics in Europe) nomenclatures.

The categories of navigable inland waterways are defined with reference to international classification systems such as those drawn up by the United Nations Economic Commission for Europe or by the European Conference of Ministers of Transport.

Rail passenger: Any person, excluding members of the train crew, who makes a trip by rail. For accident statistics, passengers trying to embark/disembark onto/from a moving train are included :Employees (staff of contractors and self-employed contractors are included)-: Any person whose employment is in connection with a railway and is at work on duty at the time of the accident. It includes the crew of the train and persons handling rolling stock and infrastructure installations Level crossing users-: Persons using a level crossing to cross the railway line by any mean of transportation or by foot Unauthorized persons on railway premises-: Any persons present in railway premises where such presence is forbidden, with the exception of level crossing users.

Actions, omissions, events, existing or pre-existing conditions or a combination thereof, which led to an IWT casualty or incident.

Refers to all diseases, morbid conditions or injuries that either resulted in or contributed to death, and the circumstances of the accident or violence that produced any such injuries. Symptoms or modes of dying, such as heart failure or asthenia, are not considered to be causes of death for statistical purposes.

The percentage of deaths attributable to a specific cause.

The product is prepared from fish eggs of sturgeon fishes belonging to the Acipenseridae family (four genera Acipenser, Huso, Pseudoscaphirhynchus and Scaphirhynchus and hybrid species of these genera).

Users of portable telephones subscribing to an automatic public mobile telephone service which provides access to the Public Switched Telephone Network (PSTN) using cellular technology.

A terrestrial radio-based service providing two-way communications by dividing the serving area into a regular pattern of sub-areas or cells, each with a base station having a low-power transmitter and receiver. Although cellular radio is primarily a means of providing mobile telephone service, it is also used to provide data services and private voice services, and as an alternative to fixed wired telephone service where this is scarce, such as in developing countries.

Cement comprises: Cement, lime and plaster (Central Product Classification Group 374). The Group is broken down into the following Classes: plasters; quicklime, slaked lime and hydraulic lime; cement clinkers; Portland cement, aluminous cement, slag cement and similar hydraulic cements, except in the form of clinkers; calculated or agglomerated dolomite.

Statistical collection involving the enumeration of all units (large sample-based collections are sometimes also referred to censuses.; FISHERIES: A fisheries census is a survey in which the value of each variable for the survey area is obtained from the values of the variable in all reporting units, that are usually fishing households. The primary objective of fisheries censuses is to provide a detailed classification of the fisheries structure of the country. It provides estimates for each household, and therefore, aggregate data for the smallest administrative, political or statistical subdivisions of the country and for classifications of households by size or other subgroups of interest.

A survey conducted on the full set of observation objects belonging to a given population or universe.
