Estimating homelessness via too-clever thinking and long train rides

[pmb]

Grar. Too much to do and think about and too much too much too much. So here's an idea I had on the train this weekend...

While riding the train, sometimes I play the game 'where would I sleep if I were homeless?' I've recently started playing a variant called 'How many of those spots are already taken?'

The resulting number is far too high. I remember when I took the train into the Bay Area, starting about two hours north of the Oakland stop I didn't see a SINGLE PLACE that looked like a good sheltering area that did not have signs of being currently or formerly inhabited. Riding the train into Portland, the line at which the density of good shelters vs. occupied shelters ratio gets bad seems to be about 30 minutes away from the station.

Since this is "distance outside of town", and area covered goes up with the square of distance, then since the bay area became bad 4x farther out of town it follows that they have 16x the number of homeless people (all assuming a uniform distribution of homeless people of course - maybe not a good assumption).

The greater Portland area has 1.5 million (-ish) people. Does the bay area have 24 million people? Answering this question should help determine whether homelessness per capita is higher around SF bay or PDX. Both of them seem like pretty good places to be homeless, so I would expect them both to be higher than, say, Fairbanks.

FAI? Hmmm...

A fascinatingly simple and intriguing attempt at a hard-to-crack statistic. Controlling for the geographic oddities of any specific metro area and all of the other factors listed above may prove to be so assumption-riddled as to make the result less than satisifying, but I like it anyways.

Extending it to Fairbanks (do you really mean the one in AK?) could pose some unique challenges.

1) Seasonality. How many homeless live outside when its -40F? I imagine the answer is not zero, but is also not equal to the summer population.

2) Just ain't urban enough. I've never approached FBX via train, but I'm thinking the 'urban' - rural transition is rather more distinct than in areas with more people to throw around.

3) Harder to define 'homeless', because it's harder to define 'home'. Where exactly is that shifting line between 'rustic Alaskan retreat', 'cabin in progress', look at me plywood and blue tarp castle, Arrrr', and 'homeless camp'? We were driving around Sutton a few weeks ago, and the line sure as hell blurs out there.

I did mean Fairbanks, AK. I always assumed that the homeless population at -40 degrees was pretty much zero.

Huh -- well, crumb! Yesterday I commented on homelessness in Fairbanks (I believe it would have been one of the first comments on your post) but apparently its bits have been devoured.

There are homeless people in Fairbanks. As one would expect, the homeless population varies seasonally, dropping to nearly zero in winter.

As akjdg points out, Fairbanks is only urban in comparison with the rest of Alaska. For a sense of scale: the Fairbanks North Star Borough has a population under 100K but is significantly larger than Massachusetts; I just turned on Google Earth and you can see pretty much all of "downtown" Fairbanks from 7000 feet (it covers on the order of 1 square mile). I can't recall seeing panhandlers in Fairbanks, though I grew up outside of "downtown".

There is a much much bigger population of home-ful alcoholics in Alaska -- waaaaaay bigger.
