Redrawing borders
3 Dec

In my water research, reading about states fighting over water allotments, I’ve begun to wonder about our need for borders. Are our geo-political borders really representative of the needs of different groups of people, reflective of actual demographics, or are they mostly arbitrary? I’ve wondered whether it’s possible to map according to fluctuating lines of various statistical, demographic or economic boundaries instead.
Yesterday I found some indication that others think the same way! Tim De Chant writes a blog called Per Square Mile blog that deals with the advantages of living in dense population centers. In a recent post, he talks about the idea of redrawing the USA based on meaningful rather than geo-political borders:
A recent paper by a group of geographers, sociologists, and mathematicians has again reconsidered the layout of the lower 48 states. Though they don’t go so far as to propose a replacement map, their study sought to determine which of today’s borders have real meaning. To do so, they used bill tracking data from the site Where’s George. If you’ve handled a $1 bill in the last decade, chances are one came stamped with a short note and a URL. Upon visiting the site, you’re prompted to enter the bill’s serial number and report your current ZIP code. On the surface, it seems like a curiosity. But buried within is a trove of anonymous data on human movement and interaction.
Data from the tracked dollar bills revealed a map that in most ways is drastically different. Though there are 48 states, the researchers found evidence of only about 12 distinct regions. The Midwest remained largely in tact, as does New England. But Pennsylvania was split in two by the Appalachian Mountains, while the southern half of Georgia was given over to Florida (which in turn lost part of its panhandle to a new Gulf shores region). And as far as Where’s George data is concerned, most of the western United States is indistinguishable.
It’s a bit of an incomplete thought, but our understanding of allegiances and complex issues may be very different if our visual and conceptual understanding of geography reflected various overlapping layers of demographics and statistics rather than single two-dimensional maps. Adding a third dimension to our ability to manipulate data may change how we see the world.
And perhaps we wouldn’t be so tribal in our handling of conflict. Just a little food for thought.
