Hello -
I am working with a student on gerrymandering and he has proposed looking at the polling districts in our county in which the drive time to each polling location is minimized while serving the same approximate population. The districts will be based on the boundaries of the census blocks.
Using the polling places as the facilities and the census block centroids as the demand points, I've tried running a Minimum Impedance solution using the census block population as a weight. From there, I would extract the facilities name and census block FIPS code, dissolving my census blocks based off the facility that my NA output gave me. I've had some solutions, but the populations vary a lot between my solutions.
Any ideas how to solve this? I'm not a NA expert and I'm having a hard time wrapping my head around how to bring in the population / weight component. I know in rural areas, the weight * impedance factor will be higher.
Thank you for any input.
