Each measure of compactness captures a slightly different geometric principle, therefore each measure disagrees in their assessments of districts' shapes. These top ten lists allow you to compare the districts rated least compact by each measure, at each legislative level. By clicking on a district, you will see how many times it is repeated throughout these top ten lists.


What does a low compactness score mean?

But a non-compact district might not have been gerrymandered at all. No mathematical technique—such as the generation of a compactness score—is likely to adequately correct for all of the geographical and social variability that can result in irregular district shapes.
