WHY USE CHOROPLETH MAPS?

Maps situate data stories in places. Maps bring evidence home. By providing a sense of context, scope and proximity, they make data personal.

Choropleth maps can be used to show the intensity of a problem, support, or policy coverage with the saturation of color overlaid on an area map. This makes it easy to tell where more work needs to be done.
