Voluntarily reporting from Avinor to Statistics Norway.
Regulation No 437/2003 of the European Parliament and of the council of 27 February 2003 on statistical returns in respect of the carriage of passengers, freight and mail by air. Commission Regulation No 135/2003 on carrying out regulation No 437/2003.
Avinor reports the same figures to Eurostat.
The purpose of this survey is to publish data on passengers and goods transported through Norwegian airports. This survey contains data on both scheduled and charter traffic to and from Norwegian and foreign airports. Avinor has published transport statistics by air for many years, and is publishing monthly figures on air traffic at www.avinor.no.
Public authorities and research institutions are using the statistics when conducting transport planning and producing transport models. Other important groups of users include enterprises within transportation and transport planners. Statistics Norway is using the data when producing the domestic transport performances. The figures are also included in the national accounts and in the energy account.
The survey includes all Norwegian airports with civil air traffic.
Data files from Avinor.
No sampling.
Data files are received from Avinor quarterly.
The figures are controlled against monthly press releases published by Avinor, and against data published by Eurostat.
The data files are aggregated by airport and month. The figures are published as received by Avinor.
There are no problems with confidentiality since Avinor publishes monthly figures by airport.
Scheduled traffic is the ordinary traffic where the seats are available for the public purchase and are operated after a timetable. Charter traffic is non-scheduled services for remuneration other than those reported under scheduled services. This also includes taxi flights. Domestic traffic is traffic between Norwegian airports. International traffic is traffic between a Norwegian and a foreign airport. Direct transit passengers are passengers who continue their journey on a flight on the same flight number as the flight which they arrived. Transfer passengers are passengers who continue their journey on a flight not having the same flight number as the flight on which they arrived.
Airports. Airports with less than 100 thousand passengers per year are grouped in Other airports.
The airlines or their agents report detailed data on air traffic and air movements to Avinor four times a month. The charges at Avinor are based on departures and not on arrivals. Therefore the reported figures are more correct for the departing air traffic. The published data might therefore deviate from the real passenger figures, and most for the arriving air traffic. Missing reports or late reporting from the airlines or agents might explain the deviation in the figures, and Avinor will in those cases estimate a number of passengers for the flight. The uncertainty in the figures is lowest on aggregated level. The figures can deviate with 5 per cent on aggregated level, and up to 10 per cent on more detailed level.
In 2004 and 2005 there are used aggregated figures from the airports, due to poor quality in the data files from Avinor. The figures are reported annual and not quarterly for these years.

The statistics is published from the year 2003 and onwards. Statistical Yearbook has contained air transport statistics for several years, but is based on a different reporting from Avinor than the data files mentioned in section one.
The statistics are comparable with air transport statistics from Avinor at www.avinor.no.
Air transport statistics are also included in the survey Domestic transport performances (www.ssb.no/english/subjects/10/12/transpinn_en/). As compared to the Air transport statistics, the Domestic transport performances count the number of journeys and not the number of passengers. The figures for air traffic will therefore deviate between these two surveys. For example, one traveller from Alta to Bergen is counted as one in the Domestic transport performances survey, even though this journey is comprised of several flights. In the Air transport statistics this journey are counted for every flight getting from place of departure to place of destination.
The statistics are published on the internet at www.ssb.no.
The micro data is stored temporarily in the programming language SAS, and is stored permanently as text-files.
