Town of Bethlehem Divided Into Four Equal Population Districts

About Town of Bethlehem Divided Into Four Equal Population Districts ....

Like most towns in New York State, Bethlehem doesn't have Wards. All elected officials are elected at-large.

But could you draw equal population districts that represent actual communities of interest? Not looking a demographics or political competitiveness, but actual communities of interest based on my knowledge of the town -- like Slingerlands, Delmar, Elsmere, Glenmont or South Bethlehem, and have them come out to be equal population? I tried, and here was the results.

There are different ways to look at this problem. One could use an algorithm to draw districts, although I've yet to find one that does a particularly good job. Turns out it's hard to automate district drawing, as often different demographics live next to one and another, and you get stuck with pockets of similar demographics living on opposite ends of the town. You end up packing and cracking or splitting similar demographics, unintentionally. It always seems like equal population is enemy of building communities of interest.

Drawing districts is a fascinating GIS question. But often the best districts are still drawn by humans, watching the totals add up in redistricting plugin, and then looking at maps of demographics. And that involves a lot of acceptance of the fact that districts you have drawn still have a lot of problems with packing and cracking. I don't like how this ultimately came out, but the equal population constraint really causes a lot of problems. Having more districts, might help solve the problem.

The qgis plugin I used for this was the Statto Software Redistricter, using a PL 94-171 Census Data joined against the block-level files. I didn't load any political or demographic graphics, just raw population along with my knowledge of what the neighborhoods look like from a map and having explored them in person, with a goal of grouping highly dense and very rural neighborhoods separately. A goal that was largely a failure in this effort! But it is a fun thought experiment.
