Measuring the seasonality in tourism with the comparison of different methods

Most of the European Mediterranean countries are suffering from seasonality and the problems caused by it. By applying different methods, this study proposes to measure seasonality in a Mediterranean country, Turkey. Studying seasonality and its measurement with the comparison of different methods could first provide useful guidelines for the countries, which may have similar problems, and could also broaden the current view in the related literature since the focus is also on the comparison of the widely used methods in the literature. The study depends on the current literature and makes evaluations based on the secondary data acquired from the statistical publications of The Turkish Ministry of Culture and Tourism. The findings reveal that none of the methods is superior to any other.
