Population growth, urban densification and shortage of available land make the construction of tall buildings increasingly prevalent. Given the world population growth, the volume of high-rise construction is steadily rising. Previous literature identifies skyscrapers as a potential source of negative externalities due to their high carbon footprints, and negative environmental features (reduction of sun light and wind-tunnel effects). The current study is the first to provide evidence supporting the notion that skyscrapers may also be considered a source of a positive externality. Based on data from 50 US states over a 19-year period (1999–2017), we demonstrate projected connection between the prevalence of melanoma and high-rise construction per state. This result might be attributed to the shadier environment created by these structures. Findings suggest that the annual projected increase in melanoma cases may be offset by approximately 53 additional high-rise buildings per state. Research findings may be of assistance to city planner. Potential saving associated with reduction of melanoma prevalence in terms of lost productivity and life lost should be considered. In addition, Caucasians with above 50 nevi as well as those with a personal or family history of melanoma should be encouraged to live in urban environments with tall buildings. •Previous literature focus on negative externalities of high-rise buildings.•Objective: to investigate a positive health externality of high-rise buildings.•Sample: data from 50 US states over a 19-year period (1999-2017).•Results: 53 additional high-rise buildings per state offset the annual melanoma increase.•Repercussions: City planners should account for health considerations (melanoma).
