My concern is that this would make use of non-GM created data essentially impossible, unless you're willing to add up figures county by county.
I'm going to have to agree with SJoyce here; quite frequently, when drafting legislation, I will use statistics compiled by the RL statesin regards to population, median incomes, the cost of living, etc. Completely re-drawing the map would make it very, very difficult to establish these statistics without tripling the GM's workload. I would also add that this map does not respect existing regional boundaries, and so would require a constitutional amendment.
