Most Livable Cities Revisited
In response to the many, many attempts to rank cities, I decided a decade ago to create my own "livable city rankings." The rankings addressed crime, transit use, and walkability, and concluded (not surprisingly) that New York was the most livable city if housing costs were not a factor. When I considered housing costs, Ann Arbor came in first.
A decade has passed, and it occurred to me to see if anything has changed But rather than using the same methods, I decided to include a variety of different factors, to reflect some of the responses to my first attempt. I decided to use a simple measure of crime; rather than weighing multiple types of crime, I merely double-weighted murder I did this for two reasons. First, I suspect that homicide is more likely to be reported to the police than, say, a burglary or purse-snatching. Second, it seems to me that focusing on the most major crime sharpens the distinction between the most troubled cities and the rest of the United States. However, this method does have one negative side effect: it required me to focus on major cities, since most suburbs and small towns have very few murders. By contrast, the old method allowed me to compare suburbs to each other.
I also shifted my transit and walkability measurements. Originally, I used three measurements: transit mode share as a percentage of the poverty rate (to avoid favoring cities where people used transit because they are poor rather than because transit service is excellent), transit mode share, and walking mode share. I kept the first measurement as a method of measuring transit. But the rise of Walk Score allowed me to change the last two measurements: I substituted citywide Bike Score and Walk Score measurements for mode share data; Bikescore allows me to consider the interests of cyclists, and Walkscore allows me to weigh walkability in contexts unrelated to commuting. On the other hand, I lost something by using these measurements: smaller cities and suburbs often don't have a Bike Score or Walk Score.
Finally, I decided to weigh cost of living a little differently. In addition to including the ratio between home prices and incomes, I also included data on rents (from this study comparing Craigslist ads in various cities). Using rent data had one negative side effect: the study only includes the 50 or so largest metros, so smaller cities like Ann Arbor and Little Rock got deleted.
My results are on this website, and were slightly different from a decade ago. Without cost of living, San Francisco beat New York by a razor-thin margin: the former city's superior Bike Score pushed it over the top. Boston was a solid third. Seattle was a surprise fourth-place finisher, combining adequate grades on the "car-free" indicia (transit/walking/biking) with crime rates lower than those of other transit metropolises.
What happened when I gave my two cost of living factors (rent, home costs) equal weight with crime and walkability? Seattle was a surprise first-place finisher, and Minneapolis and Salt Lake City an even more surprising second and third, respectively. These cities were not superlative in any way, but performed adequately in every category while New York and San Francisco were dragged down by housing costs. Last place was a much easier call. Birmingham, Alabama finished last both with and without cost of living—high crime and poor transit were a deadly combination.
