Nights spent on camp sites

Data for the statistics are collected monthly from Danish campsites with a minimum of 75 camping units and yearly from Danish campsites with 10-74 camping units using an online questionnaire on http://www.Virk.dk, or by using a system-to-system solution where the campsites booking system automatically sends data to Statistics Denmark. Collected data are validated on micro-level during the data collection and again on macro-level when aggregated. The validated data are then imputed with missing values and afterwards aggregated into geographical and nationality totals.

Source data

The statistics "Nights spent at campsites" are based on monthly reports from campsites with at least 75 units that are registered in the Danish Business Register. Campsites with 10-74 units that are registered in the Danish Business Register report on an annual basis.

Frequency of data collection

Data for the statistics "Nights spent at campsites" are collected monthly for campsites with a minimum of 75 camping units and yearly for campsites with 10-74 camping units.

Data collection

Data are collected via an online questionnaire on http://www.virk.dk, or via a system-to-system-solution where the camp site booking system automatically sends its data to Statistics Denmark.

Data validation

The collected data are compared with the data from the previous year and potentially significant changes are examined, explained and corrected in case of errors. There is also a cross validation making sure that the values given under the different variables are plausible. Afterwards, data are aggregated into geographical and nationality totals and data are then validated on macro-level before publishing and by comparing time series.

Data compilation

If an enterprise does not disseminate data within the given time frame, data from the same month the year before is imputed. If the enterprise later on disseminate data the imputed data are replaced.

Number of nights are calculated as number of guests multiplied by the lenght of the stay. E.g. 2 guests staying at a campsite for 5 days are equal 10 overnights.

Arrivals are the number of guests no matter the lenght of the stay. In the example above with 2 guests, the arrivals are 2.

The number of nights at permanent leased pitches are calculated in the following way: the factor of the overnight multiplied by the number of permanent leased pitches. The factor of the overnight for every month is:

January-March: 5

  • April: 18

  • May: 21

  • June: 24

  • July: 42

  • August: 27

  • September: 15

  • October-December: 6

E.g if the number of permanent leased pitches in July are 25, the number of nights in July are 42 multiplied by 25 equal 1050 overnight stays. The factor of the overnight for every month is based on the assumption that the average number of guests per night are 3. Furthermore it is assumed that the average number of nights at permanent leased pitches in July are 14.

The average number of nights for every month are:

  • January-march: 1,67

  • April: 6

  • May: 7

  • June: 8

  • July: 14

  • August: 9

  • September: 5

  • October-December: 2

No grossing-up procedures are used as this is a census with a cut-off limit of at least 75 camping units for the monthly statistics and for the yearly survey a census with 10-74 camping units. Data are aggregated into geographical and nationality totals and subsequently validated on macro-level.

The most recent data is always available in the StatBank.

Adjustment

Data on campsites is seasonally adjusted.
