Forbes Magazine released an article of "America's Fastest-Recovering Cities" on November 19th, also producing a ranked list of America's 100 fastest recovering cities.
Unfortunately for Forbes readers, the list contains methodological issues which limit its usefulness in determining the "fastest recovering cities".
The most outstanding issue is the use of "levels" of economic indicators to measure recovery, as opposed to their changes. For example, the author uses the unemployment rate in the ranking system. The current unemployment rate has nothing to do with how quickly the labor market situation has improved, which is more accurately reflected by changes in the unemployment rate. Low unemployment rates might be a good measure of the "most stable cities", but not the "fastest recovering".
Let's compare two cities to see how using "levels" of economic variables is not that informative. Omaha's "Unemployment Rank" was No.1 in Forbes' list, with a 5.3% unemployment rate, while Wichita's "Unemployment Rank" was No.42, with an 8.6% unemployment rate. This indicates that Omaha's economy was not wrecked by the recession, which is great for Omaha. But that has nothing to do with how quickly the economy has improved, as suggested by article's "Fastest-Recovering" title.
You can see from the table below that Wichita, KS had higher unemployment than Omaha, NE before the recession even started, but its labor market situation has improved more dramatically since – in both absolute terms and relative terms. Wichita's unemployment rate is down 1.4 percentage points since July, while Omaha's unemployment rate is only down 0.5 percentage points. Relative to their respective July unemployment rates, Wichita's drop represents a 14% improvement, but Omaha improved only 9.4%. So, which city improved the fastest?
| State | Date | Unemployment Rate | Absolute Change | Relative Change |
|---|---|---|---|---|
| Omaha, NE | OCT 2008 | 3.5% | - | - |
| Omaha, NE | JUL 2009 | 5.3% | +1.8% | +51% |
| Omaha, NE | OCT 2009 | 4.8% | -0.5% | -9.4% |
| Wichita, KS | OCT 2008 | 4.3% | - | - |
| Wichita, KS | JUL 2009 | 10.0% | +5.7% | +132% |
| Wichita, KS | OCT 2008 | 8.6% | -1.4% | -14.0% |
What matters is: what's the unemployment rate in Omaha now, compared to before the recession; what's the unemployment rate in Wichita now, compared to before the recession; and how do those two differences compare to each other? In statistics, this method is called the "difference-in-difference estimator", which factors out local market particularities, for example the fact that Wichita had systematically higher unemployment than Omaha before the recession even started.
