Preservation of communities defined by actual shared interests, known as communities of interest, is a traditional districting principle for many localities. You can identify a community of interest by creating a named selection set using the standard Maptitude selection tools. For more information on selection sets, see Working with Maptitude Selection Sets (Filters) (https://www.caliper.com/learning/media/working-with-maptitude-selection-sets-filters). In most instances, you will create a community of interest by selecting areas in the of the (census blocks).
Once you have identified the communities of interest in your , if you try to reassign a portion of a community of interest to another district, the entire community of interest gets reassigned. You can also lock a community of interest so that no portion of it can be reassigned to another district.
