The Wisconsin Dept. of Health Services collects data related to population density, health factors, natural and built environments, and demographic and socioeconomic factors to track negative impacts extreme heat can have on vulnerable populations such as elderly populations, socially isolated people and those with pre-existing chronic conditions. This data is used to create heat vulnerability indices (HVI) to identify areas of greatest risk for negative health impacts due to extreme heat for the entire state of Wisconsin, by county and for the greater Milwaukee urban area.
The heat vulnerability indices are available in the Wisconsin Digital Archives along with other resources related to managing extreme heat:
