The aim of this project is to explore the relation between graffiti writing and the measures by the authorities to limit such actions. In spite of a growing research on the graffiti subculture as well as an increased public debate on the costs of graffiti removal there exists no Swedish evaluation of how well anti-graffiti measures work. More so, the existing research on graffiti has been preoccupied with a tension between the legal and illegal aspect of the subculture, relating it to one of art and vandalism, instead of pursuing the more thorough differences these studies imply in regards to how the 'where,' 'how,' and 'why' of graffiti are defined by writers. This project will take as its point of departure such internal differences, relating them to how graffiti writers perceive, interpret, and act upon public space as well as the measures by the authorities: How are boundaries between binary pairs such as legal/illegal, authentic/fake, public/private, art/vandalism defined and worked in relation to each other? And how are such definitions and boundary work extended to the 'where' and 'how' of graffiti writing? Methodologically the project is inspired by urban ethnography. I will interview participants through group interviews and "go alongs", the latter pointing to city walks with individual writers, pursuing how they view and make use of public space. Themes developed and elucidated during these walks will be be pursued through group interviews with participants.
