Rules The Challenge

Assigned the responsibility of using demographic information from the 2010 Census to create legislative boundaries for the Philadelphia City Council. Each plan must meet the requirements below to be considered legally acceptable; otherwise, it will be excluded:

Contiguity

Philadelphia employs voting precincts. The plan's districts must be made up of adjacent ward divisions. Philadelphia permits single-point contiguity (ward divisions are regarded as "contiguous" even if they only meet at a single spot).

Compactness

The Schwartzberg measure was used throughout the competition. This was a measurement that compared the district's perimeter to the diameter of a circle whose size is the same as the district's area to determine compactness.

Equipopulation

Regions should have a nearly comparable population distribution. The City Charter contains no legislative requirements in this regard, however plans with more equitable district population distribution a better rating.
