Finland and Sweden share a common history that dates back to the 12thcentury, when the two countries were one. Sweden has throughout time, for numerous reasons, been a more well-developed country and has had a larger economy than Finland, which has made moving and travelling to Sweden amongst Finns a rather common demographic feature. The effects of this historical relationship, and of these events, still to this day influencethe travel patterns between the two countries; More Finns visit Sweden than Swedes visit Finland.Throughout this thesis I analyse and describe the uneven passenger transportation patterns between the Swedish city of Umeå and the Finnish city Vaasa. By analysing inhabitants personal background together with the motives for travelling to-, the knowledge about-, and the perceived mental distance between Umeå and Vaasa of inhabitants in both cities, I strive to find answers to the Bothnian disparity routes. The results of the study points towards social bonds, various cultural factors, possession of knowledge, and perceived mental distance playing asignificant role in shaping the travel patterns between the two cities. Furthermore, the result of the study also provides a perspective on how geography is not just a physical structure but also a significant factor in understanding human mobility and interaction in cross-border contexts.
