Statistical processing

Source data

The accommodation statistics is based on data from Danish hotels, motels, inns, B&Bs, holiday centers, hostels and similar with a minimum of 40 permanent bed places as well as all hostels with a DanHostel-membership. The population is based on data from The Danish Business Register.

Frequency of data collection

Data is collected on a monthly basis.

Data collection

The accommodation statistics is collected either online via Virk or by using a web-application where the accommodation businesses can extract and report directly from their booking systems to Statistics Denmark. Respondents are legally obliged to report data and the data collection is digital.

Data validation

The data collected is compared with the data collected for the similar month the year before and significant or implausible changes are examined, explained and corrected if needed. The variables are also compared with each other and it is examined whether the data adds up correctly.

Data compilation

The data is collected from the accommodation businesses and validated. Then the data is aggregated into different geographical levels based on the NUTS-classification.
The census is mandatory and with a cut-off of minimum 40 bed places as well as all hostels with a DanHostel-membership. In addition, an annual survey is published every year from 2019 on smaller hotels and similar, holiday centers and hostels with 10-39 bed places. Data from the same reference period the year before will be imputed if a respondent does not report data within the given time frame.

Adjustment

The accommodation statistics is seasonally adjusted by using an ARIMA-model where are business days and Easter is taken into account. Pentecost is not adjusted in the model yet.
