All Recessions are Not Created Equal

In an announcement that was of little surprise to most of us, the National Bureau of Economic Research (NBER) finally declared that the United States has been in a recession since December 2007. What may not be quite as well known is that not every state is necessarily undergoing an economic recession at any given time. I thought it might be interesting to see which states are doing well despite the recession and which states are suffering the most.

To do my analysis, I downloaded the historical data spreadsheet (Excel file) of the State Coincident Indexes, which is published by the Federal Reserve Bank of Philadelphia. This is a long-running series of indexes that has been published since 1979. What the coincident indexes do is:

...combine four state-level indicators to summarize current economic conditions in a single statistic. The four state-level variables in each coincident index are nonfarm payroll employment, average hours worked in manufacturing, the unemployment rate, and wage and salary disbursements deflated by the consumer price index (U.S. city average).

Based on this index number, individual state economies can be compared against each other and the nation as a whole to see how well the state is doing. The Philadelphia Fed also create month-by-month color-coded maps so that one can see at a glance each state's performance. Below is the most recent map available, from October 2008. (You can find all of the previously published maps since January 2005 here.)


Looking at the data since December 2007, when the recession officially started, what we find is that fourteen states have actually had economic growth as a percentage change over the past eleven months. Thirty-five states have had a contracting economy while one state (Kansas) has had neither a recession nor growth (a 0.0% "change"). (There is no data for the District of Columbia.) The fourteen states, in order of decreasing economic performance, are: Wyoming, Texas, South Dakota, New Hampshire, North Dakota, Virginia, New York, West Virginia, Colorado, Oklahoma, Louisiana, Nebraska, Massachusetts, and California. What's surprising to me is that California is in this list as they currently have the third highest unemployment rate in the country.

On the other side, the bottom ten states since last December are Delaware (41st), Arizona, South Carolina, Pennsylvania, Rhode Island, Michigan, Idaho, Nevada, Washington, and Oregon (50th). All of these states have had their index drop by at least 2.2% since December and, in the cases of the latter four, by over 4.0%. (Oregon's index has dropped by a whopping 6.1%.)

Of course these index numbers can change significantly from month to month. Both Oregon and Nevada have seen their index numbers drop by double digits within the eleven-month span (and not for the better). However, while things may look gloomy for some individual states, the economy may become better for them within a short period of time while the rest of the country labors under the current recession.

State Coincident Indices Through August 2008

The State Coincident Indices, published by the Federal Reserve Bank of Philadelphia, have been released through the month of August. The top graph is from the month of May, which I've republished to provide some continuity from the previous set of graphs; the latter three graphs are for June, July and August.

As you can see, there has been some strengthening in the Gulf states of Texas and Louisiana (one wonders how the graphs will look after taking into account Hurricanes Gustav and Ike), the western half of the upper Midwest, and West Virginia, which went from deep red to dark blue in a matter of two months. Trouble spots include the Pacific Southwest and the Midwest, although the latter region may be improving; we'll have to wait and see.

From the August 2008 press release [pdf]:

The Federal Reserve Bank of Philadelphia has released the coincident indexes for all 50 states for August 2008. The indexes increased in 12 states for the month, decreased in 31, and were unchanged in the remaining seven (a one-month diffusion index of -38). For the past three months, the indexes have increased in 12 states, decreased in 35, and were unchanged in the other three (a three-month diffusion index of -46). For comparison purposes, the Philadelphia Fed developed a similar coincident index for the entire United States. The Philadelphia Fed’s U.S. index was flat in August and has remained unchanged over the past three months.

State Coincident Indexes

Every month, the Federal Reserve Bank of Philadelphia produces a "State Coincident Index" that allows economists to see how well each of the individual states are doing economically:

The coincident indexes combine four state-level indicators to summarize current economic conditions in a single statistic. The four state-level variables in each coincident index are nonfarm payroll employment, average hours worked in manufacturing, the unemployment rate, and wage and salary disbursements deflated by the consumer price index (U.S. city average). The trend for each state’s index is set to the trend of its gross domestic product (GDP), so long-term growth in the state’s index matches long-term growth in its GDP.

What the graphs below show is a state-by-state analysis of the economy. The first three maps show the month of January for 2005, 2006 and 2007, respectively. (Note that in these maps, a five-point scale is used with dark blue being the best and dark red being the worst.) The last six maps are for the last six months available, December 2007 through May 2008. While the scale has been increased from five points to seven points, the same basic color scheme is still used; i.e., dark blue is the best, dark red is the worst.

As you can see, the American economy has gotten quite bad over the past six months, especially in the Northwest and, to a slightly lesser degree, in the Midwest and South. Some of the states in the Mountain West and Northeast are doing well, with the best state currently being Texas. (I'd be tempted to say that Texas is doing well because of the multiplier effects from higher oil prices, but if that's the case, then why isn't Alaska doing well too?)
