The impact of wildfire is not only determined by fire magnitude, but also by the predispositions of those who are affected, which is described by differences in social vulnerability. In this study, Swedish event reports on Wildland-Urban Interface fires that occurred between 1996 and 2022 were used to identify features of social vulnerability that are central to a Nordic setting. Results on both census tract scale and on household scale highlight that living in a sparsely populated area increases vulnerability to wildfire.
