The aim of this essay is to study population change in tourism intensive mountain municipalities. Then to investigate whether center displacement takes place from the municipality center to the area with growing tourism. Areas of growing tourism have in this study been delimited to ski resorts. To answer the study’s purpose and questions, both quantitative and qualitative methods have been used. Population statistics have been used to explain population change in Swedish mountain municipalities. Population statistics showed that there are four mountain municipalities that have a shrinking population in the municipality and in the municipality center, while there is a ski resort with population growth in the municipality. These mountain municipalities are Dorotea, Malung-Sälen, Storuman and Härjedalen. Interviews with officials from these municipalities have been used as a complement to analyze the findings from the population statistics. The result of the interviews shows that the ski resorts have characteristics of being so-called ‘center’ with reference to the center-periphery model. At the same time, it also appears that the informants do not think that it is possible to talk about any tourism-driven center displacement. At least not with regard to public service. The municipality house will be remain located where it is today. Based on the given results, this essay conclude that ski resorts should be regarded as commercial centers and that the municipality center is the public center. From this aspect this study also conclude that there is possible to talk about a patriell center displacement from the municipality center to the ski resorts. Which, based on this study, is explained as commercial. The study also conclude that the commercial supply is dependent on the tourist visitors and those who work on the ski resorts, where the result shows that much of those who live in the ski resorts work in the touristindustry. In this way, the commercial center displacement also becomes tourism-driven.
