City destinations are central in the study of tourism. But how can visitor streams related to the destination characteristics and visitor segments be analysed and discussed as a basis for improvement of the destination? This research used statistical data and qualitative information as “knowledge indicators” rather than as “unambiguous facts”. The research included analysis of about 100 destination plans, a pilot study of statistics and qualitative destination information about Stockholm, and a literature review. It resulted in the development of the visitor stream concept, which can be used in future research on the integration of various visitor segment streams. A method for analysing visitor streams is suggested: (1) defining “focused destination” and its characteristics, (2) investigating quantitative and qualitative destination information, (3) identifying visitor segments, and (4) analysing streams with new destination tools. The knowledge gained will introduce and address new issues concerning statistics for measuring, monitoring and assessing the actual value of tourism, particularly urban tourism.
