Structure loss is an acute, costly impact of the wildfire crisis in the western United States (“West”), motivating the need to understand recent trends and causes. We document a 246% rise in West-wide structure loss from wildfires between 1999–2009 and 2010–2020, driven strongly by events in 2017, 2018, and 2020. Increased structure loss was not due to increased area burned alone. Wildfires became significantly more destructive, with a 160% higher structure loss rate (loss/kha burned) over the past decade. Structure loss was driven primarily by wildfires from unplanned human-related ignitions (e.g. backyard burning, power lines, etc.), which accounted for 76% of all structure loss and resulted in 10 times more structures destroyed per unit area burned compared to lightning-igni..., See associated paper., Data are primarily in .csv format, opened with a range of programs, and also in Matlab .mat format. Code is written in Matlab (open source option: SciLab, https://www.scilab.org/).
