Heat Vulnerability Data Explorer

This project used existing population and census data, natural and built environment data, and health factors data to create a heat vulnerability index (HVI) to identify areas of greatest risk for negative health impacts due to extreme heat in the entire state of Wisconsin and the greater Milwaukee urban area. The maps can help identify high-risk neighborhoods and populations to receive targeted messaging related to heat events and additional resources during extreme heat events.

Please visit the Climate and Health site for a list of specific indicators that were used in the analysis.

Instructions

About - Click to view information about the Heat Vulnerability Data Explorer. This section has a link to the Climate and Health Program website and information about the data.

Select a map - Click the drop-down menu to view and switch between the map options.

Compare map - Click the on-off button to turn it to the On position. When the button is in the On position a second map will appear. Use this to compare two datasets.

Search - Search an address, city, ZIP or place and the map will zoom to that location.

Legend - Click to view the color-coded data categories used for each map. Other data layers selected will appear as well. Below the legend there will also be a definition of the data.

Layers - Click to view available layers. Selected layers will appear on the map. There are geographic boundary layers like county boundaries and Senate districts.

Default map view - Click to have the map return to the default view of Wisconsin.

Review multiple block groups - When zoomed out in the map, multiple Block Groups may be selected. Use the arrows to navigate between multiple block groups or zoom in to choose a specific block.
