Are you saying that in 2020 it may be that neither macrochop of Douglas or Sarpy would allow for a packed CD without an extra chop into a subunit and without an offsetting erosity reduction?
Hmm.
I'll have to look at my estimates for NE.
What is the definition of the pack and cover rule?
Definition: County Cluster. A connected set of counties sharing a common demographic feature. Connected means able to travel within the cluster to all counties on public roads or ferries without leaving the cluster. The size of a county cluster is the population of the cluster divided by the quota, and rounded up to the nearest whole number.
Definition: Cover. The cover of a cluster is the number of districts including all or part of any county in the cluster. The cover score for a cluster is the difference between the cover and the size of the cluster.
Definition: Pack. The pack of a cluster is the number of districts wholly contained within counties in the cluster. The pack score for a cluster is the difference between one less than the size and the pack of the cluster.
Definition: Urban County Cluster (UCC). A UCC is a county cluster where each county is within the same Census-designated Metropolitan Statistical Area (MSA), and has either an urbanized population of 25K or more, or an urbanized population of at least 40% of the total county population.
Item: A redistricting plan should avoid excess division of county clusters. The CHOP will increase by the cover score for each cluster. The CHOP will increase by the pack score for each cluster.
If the magnitude of a UCC is 1.4,
Why are CDs that are 100% and 40% within the UCC preferred to:
CDs that are 80% and 60% within the UCC
or CDs that are 100%, 25%, and 15%?
