I don't think they necessarily are. They make decisions about jobs, sun, family, the beach, comfort and contentment (among others). The curve is the outcome of these individual decisions - but trying to infer back from the curve is dangerous. The Schelling ref. was a simply that individual decisions on a micro level can have unintended macro consequences. This looked like a possible case. It may not be.

There are only half a dozen block groups with population densities in the thousandths of a person per sq. mi. range, most with populations in the single digits. I would guess that it would actually be a big deal to quadruple the population of these area, since they're generally mountainous and inaccessible.<BR/><BR/>I believe that there are a few empty block groups. They were ignored when I crunched the data.<BR/><BR/>@paul soldera - Census tracts do change over time, albeit not radically. I'm not sure I understand you reference to Schelling. I can assure you that there is a vast qualitative difference between the settlement patterns in the mountains to Alaska, Sun Belt suburbs, and the high-rise apartment districts of major cities.humble bipedhttps://www.blogger.com/profile/06047100865842860655noreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-28614868551082392122008-07-18T10:16:00.000-07:002008-07-18T10:16:00.000-07:00I wonder if this - http://www.fakeisthenewreal.org...I wonder if this - http://www.fakeisthenewreal.org/by_density/?classing=quantile&units=sqmi&div=50 - is a bit misleading as it pertains to why we choose to live where we do.

I am sure someone has done this. As for census block definitions, if I recall correctly, census tracts are the smallest break and they are kept consistent over time to make for apples-to-apples comparisons of census data. I guess you could get one that has no population due to out-migration, but something tells me the stats guys wouldn't like this, and they'd re-draw the boundaries.Paul Solderahttps://www.blogger.com/profile/14934770101157073208noreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-28991026324508735402008-07-18T05:51:00.000-07:002008-07-18T05:51:00.000-07:00Population density is a far more critical topic th...Population density is a far more critical topic than you may imagine.
