Number of commercial airports
methods, notes and classification
DATA_DESCR The Questionnaire on Air Transport Statistics is aimed to collect aggregated annual data on the air transport sector for the following domains: I. Infrastructure (covering commercial airports only) (status at 31/12) II. Transport equipment (covering commercial aircrafts only) (status at 31/12) III. Enterprises, economic performance and employment (status at 31/12) IV. Accidents (annual data) Data are collected and disseminated at country level or at airport level for major European airports. The questionnaire is not supported by any legal acts and it is based on a gentlemen's agreement with the participating countries (Member States, Candidate Countries and EFTA countries). It is usually prefilled by Eurostat using its own sources as well as other ones (e.g. Airclaims or EASA) and sent to the countries for completion and validation. The completeness varies from country to country. Please note that information concerning data collected in the frame of the Air Transport Statistics Regulation can be found in the metadata documentation provided for this domain (Air Transport Measurement). The section on "Infrastructure" contains three tables: Number of main airports (with more than 150 000 passenger movements per year) and other airports with more than 15,000 passenger movements per year) at country level Airport infrastructures by type at airport level Airport connections to other modes of transport at airport level. The section on "Transport Equipment" contains two tables: Commercial aircraft fleet by type of aircraft at country level Commercial aircraft fleet by age of aircraft at country level The section on "Enterprises economic performance and employment" contains three tables: Number of aviation and airport enterprises at country level Employment in aviation and airport enterprises by gender at country level Employment in main airports by gender at airport level The section on "Accidents" contains two tables: Number of injury accidents at country level Number of fatalities in injury accidents at country level.
CLASS_SYSTEM Airports are classified according to ICAO (International Civil Aviation Organization) airport coded as listed in ICAO document 7910.
STAT_CONC_DEF The majority of the definitions are based on the Glossary for transport statistics 4th edition. INFRASTRUCTURE Airport
STAT_UNIT The data used in the domain are collected at airport or country level. Each year and for each reporting country, Eurostat pre-fills the questionnaire using its own data and other reliable data sources (EASA, Airclaims): the questionnaire is sent to the countries for completion and validation. Only data validated by the reporting countries are disseminated (NB: the number of airports is always disseminated, as it is derived from Eurostat data collected in the frame of a legal basis).
STAT_POP For data at country level, the airports covered are those registering at least 15á000 passenger units per year. For data at airport level, the airports covered are the
REF_AREA The data cover the EU Member States, the Candidate Countries as well as Norway, Iceland, Switzerland.
BASE_PER Not applicable
UNIT_MEASURE The units used depend on the elements collected. For the data collected at national level, the units are: number of airports, number of aircraft, number of enterprises, number of employees (by gender), number of injury accidents and number of fatalities in injury accidents. For the data collected at airport level, the units are: number of runways, the number of check-in facilities, number of aircraft gates, number of parking places for private cars, number of connections to other modes of transport, intermodal freight area in square metres and number of employees.
