Step 5. As a final step, make sure the created districts as a group comply with the Voting Rights Act of 1965.
Verify that the resultant map is consistent with the Voting Rights Act of 1965, i.e., that the map does not unduly pack or fragment minority communities. In most instances, no further adjustment will be needed, as compact districts that respect political subdivisions most often lead to compliance with the Voting Rights Act and avoid the packing or fragmenting of minority communities.
Any problems at this stage can usually be resolved with relatively slight adjustment of district boundaries.
