Choropleth maps use color to show the count or percentage of a variable.
The Atlas uses color to show the count and percentage of all coronavirus cases, daily new cases, deaths, and hospital beds. Use choropleth maps to see data about the virus on a particular day.
For more details on how the Atlas created the choropleth maps, please see the Methods page.
1. The choropleth map is the default display for the atlas webpage. To return to the choropleth display, first select the data source and variable you would like to map.
2. Click on the Choropleth button.
3. Use the color ramp at the bottom of the screen to interpret the count or percentage for each county or state.
4. Brighter reds represent larger counts and percentages. Paler yellows represent smaller counts and percentages.
5. Click on a county or state in the map for a popup containing all data variables, socioeconomic indicators, and a disease forecast for that area.
6. Move the time slider at the top of the map to see counts and percentages on different dates.
To explore emerging trends and patterns use the Hotspot display. To explore the history of the virus use the Animated Slider and Time Graph.
