Name of collection/source Name of collection/sourceThe survey used for this exercise is the "Trends in the Transport Sector".
Data source(s) used Data source(s) usedThe International Transport Forum collects transport statistics on an annual basis from its member countries. Data are collected from Transport Ministries, statistical offices and other institution designated as official data source.
Data Characteristics Data Characteristics Link to Release calendar Link to Release calendarData are published annually on 31 October.
Reference period Reference periodData series start in 1970 and continue until the current year-1, or the most recent available data.
Variables collected Variables collectedVariables collected include inland transport of goods (T-km), of passengers (P-km) and road injury accidents. Additional information is also gathered on containers transported by rail and sea (Tons and TEU) as well as short sea shipping data (T-km).

Concepts & Classifications Concepts & Classifications Key statistical concept Key statistical conceptAlthough there are clear definitions for all the terms used in this survey, countries might have different methodologies to calculate tonne-kilometre and passenger-kilometres. Methods could be based on traffic or mobility surveys, and may use very different sampling methods and estimating techniques which could affect the comparability of the statistics. Also, while the definition of road fatalities is consistent across most countries, this is not the case for road injuries. Indeed, not only do countries have different definitions, but there is underreporting of road injuries. However, data for individual countries are consistent over time and useful for identifying underlying trends. It is recommended to read the metadata in order to check the coverage of data for each country.
