Forbes has ranked the 40 biggest U.S. metropolitan areas in terms of safety, and Portland comes in at #3. The top five are Minneapolis-St. Paul, Milwaukee, Portland, Boston, and Seattle.
While MSP certainly has a good claim to the top spot, Forbes uses a pretty weird methodology. All of the metro areas are ranked ordinally in four categories (violent crime rate, traffic fatality rate, workplace fatality rate, and natural disaster risk). The ordinal rankings are then added together, and the lower the overall score, the better.
So, first of all, the ordinal ranking can obscure big differences between seemingly close metro areas. In crime rate, for example, what if the per capital crime rates (per 1000) are something like #1 (1.1), #2 (2.5), and #3 (2.6)? The simple ordinal ranking doesn't take into account how much better #1 is than #2, and how trivial the difference between #2 and #3 is.
Second, what exactly is "natural risk disaster"? The West Coast areas get slaughtered in this category, with Portland the least bad at #25, then San Diego (#26), and everything else in the 30s. Presumably, this is anticipating major earthquakes or something, as well as wildfires and mudslides in southern California, I guess. But it seems awfully weird to be making 1/4 of the ranking based on something that you can't really estimate with precision.
Even if you could, what's the death toll from earthquakes? Focusing just on the Los Angeles & San Diego areas in the last 50 years, the only quakes with fatalities were the 1994 Northridge earthquake, which caused 72 deaths, the 1987 Whittier Narrows quake, which killed three people, and 1971 Sylmar temblor, which killed 65 people. (I'm not counting ones like the 1992 Landers quake, which did kill three people, but none in the L.A. or San Diego metro areas.) So, that's 140 people over 50 years, or less than 3 per year.
Granted, ~3 per year on average is greater than that you'd expect from, say, tornados, but the risks posed by natural disasters like earthquakes seem miniscule compared to traffic fatalities and violent crime. In Los Angeles County, there were 168 murders, 233 rapes, 1910 robberies, and 5148 assaults reported in 2008. Granted, L.A. County is not the same thing as L.A. metro area, but that only means that we'd expect even more violent crimes in the latter. In short, the number of deaths via violent crime in L.A. dwarfs that caused on average by earthquakes.
And it's not as if L.A.'s violent crime rate is off the charts -- it's ranked #21, so just one spot above average. Yet, the ~3 earthquake deaths (on average) per year is weighted the same as the 168 murders in 2008 in terms of significance, even though violent crime actually carries more than 50 times the numerical weight in reality.
I think the same criticism could be made about workplace fatalities. The number of people who die in workplace fatalities can't be that high compared to violent crime or traffic, so equating the ranking in this category with that in any other is also silly.
Now, if you focus on the two categories that seem most significant to me -- violent crime and traffic -- and re-rank using Forbes' criteria (in other words, still summed ordinal rankings), the new top 5 looks like this:
1. Portland (#1 in crime, #5 in traffic); total 6
2. San Jose, CA (#2 in crime, #6 in traffic); total 8
3. Seattle (#3 in crime, #8 in traffic); total 11
3. Boston (#10 in crime, #1 in traffic); total 11
5. New York (#11 in crime, #2 in traffic); total 13
I have to admit, I am quite surprised to see Boston and New York do so well, but I guess my impressions of Boston are colored by a 1987 visit where I nearly got run over 5 times in 30 minutes as a pedestrian, before I learned that the drivers didn't think pedestrians had the right of way. And my impression of New York is pretty much colored by the movie "Escape from New York" . . . . Anyway, seeing the relatively smaller Pacific Northwest cities and San Jose atop the list does make some sense to me!
