The purpose of the statistics on transport by ferries and passenger ships is to describe the transport of passengers and goods by ferries and passenger ships on domestic routes and in traffic between Danish and foreign ports.
The statistics are together with the other transport statistics used for analyses of the transport of passengers and goods. In the current form the statistics has been made since 1990.
The statistics on transport by ferries and passenger ships are a monthly and annual statistics on the transport of passengers and goods by ferries and by passenger ships between Danish ports or between Danish and foreign ports.
The most important variables used in the statistics are: Trips, passengers, vehicles, goods on road vehicles and other goods.
The statistics are published annually in Nyt fra Danmarks Statistik and in the Statbank.
The COVID19-pandemic haven't had any effect on neither data collection nor the quality of the statistics.
Data for the statistics are collected through an electronic questionnaire. The statistics cover all ferry lines and passenger ships with goods or passenger traffic in route to or from Denmark.
The response rate is 100 percent.
Data are checked both automatically and manually at the time of data collection and in case of large deviations or missing reports the reporting company is contacted again. For a few operators the total freight weight is imputed based on the number of freight vehicles reported. The validated micro-data is aggregated and then checked for major fluctuations.
The statistics are used regularly by new media, consultancies, business associations, port enterprises, shipping lines and other enterprises as well as Eurostat for e.g. analyses of maritime traffic, investments in infrastructure, analyses of the maritime transport sector, economic development and environment.
The statistics is assessed to be reliable as the main series are based on financial information from the reporters (ticket sale). Furthermore the reporters are obliged to monitor the number of passengers and vehicles onboard.
There is few and minor revisions and few errors are found in reported data.
The smallest ferry lines are not included in the statistics. Usually this is lines to the smallest Danish islands or crossing fjords.
In the main series uncertainty is largest for goods by goods motor vehicles that in some cases are estimated based on the number of goods motor vehicles.
The quarterly statistics are published around 70 days after the end of the quarter. Since statistics for the first quarter 2012 the statistics has been published at the pre-announced date.
The statistics are comparable with other EU- and EFTA member states statistics published by Eurostat.
The time series is comparable from 1990 onwards. In its present form the statistics is consistent since 1990 for annual figures and 2000 for monthly figures. The statistics are processed according to common EU guidelines and therefore comparable with statistics from other countries published by Eurostat.
The statistics are published quarterly with figures in Statistikbanken in tables SKIB31, SKIB32, SKIB33 og SKIB34. Besides the figures are included in Statistical Yearbook up to 2017 and Statistical 10-year review. Annual data is published in an annual news release.
