Compactness score
WebNov 23, 2024 · The compactness score of a district counts the number of block groups in a district that border a block group not in that district, similar to a district’s perimeter. By minimizing this, we can ensure that a district is compact. The Tree-Splitting Method guarantees that every district is contiguous. WebThe method was developed by lawyers Daniel D. Polsbyand Robert Popper,[1]though it had earlier been introduced in the field of paleontology by E.P. Cox.[2]The formula for …

Webof a compactness score over all regions. In particular, we consider the Polsby-Popper, convex hull, and Reock scores on the sphere, and demonstrate that for any choice of map projection, there are two regions, A and B, such that A is more compact than B on the sphere but B is more compact than A when projected to the plane. We prove our results in Weba number of ways to measure compactness, but two of the most widely used are a district’s perimeter complexity and its dispersion around its center. To measure the perimeter …

WebThe method was developed by lawyers Daniel D. Polsbyand Robert Popper,[1]though it had earlier been introduced in the field of paleontology by E.P. Cox.[2]The formula for calculating a district's Polsby–Popper score is PP(D)=4πA(D)P(D)2{\displaystyle PP(D)={\frac {4\pi A(D)}{P(D)^{2}}}}, where D{\displaystyle D}is the district, P(D){\displaystyle … WebA COMBINATION SCORE We might notice: skew and convex hull scores have complementary blind spots. Convex hull gives a perfect score to arbitrarily long, skinny rectangles. Skew gives a perfect score to a square that is carved out like a swiss cheese. So maybe we can propose a combination Box Score that sums the two. xy-Hull=.5 xy …
