Custom regions
A custom region is a collection of places that you define, such as a service area, market, or part of a state. When you create a custom region, you can select it across any visualization and data will be populated for that custom region. For example, you can create a Custom Region that includes all of the Zip Codes your Health System covers or all of the census tracts that overlap with the area your Health Department serves.
You can add or change your custom regions at any time.
