**4. Methodology**

*4.1. Data*

The data on overnight stays at campsites were provided by Statistics Norway (SSB). In the dataset from SSB, it was possible to analyze countries of origin and visits by month and year. The Norwegian central bank (Norges Bank) provides an ongoing overview of exchange rates, and we took advantage of this information in our analysis. Figures for the consumer price index (CPI) and gross domestic product (GDP) were from data published by the World Bank. The sample period was from 2000 to 2019. In this study, the focus was on only two visiting countries, Sweden and Germany. Sweden is a neighbor of Norway, and the country has its own currency (SEK). Germany is the most important visiting country (see Figure 2).
