In terms of length, the longest post-Depression economic decline was 16 months, which occurred in both the 1973-75 and 1981-82 recessions. This recession began in December 2007, which means that it will enter its 17th month next Wednesday.
The current recession is also more widespread than any other since the Depression. The Federal Reserve's readings show that 86% of industries have cut back production since November, the most widespread reduction in the 42 years the Fed has tracked this figure.
What's more, every state reported an increase in unemployment this past December, the first time that has happened in the 32 years that records for unemployment in each state have been kept.
"This is important because there's nowhere you can move to find a job," said Gus Faucher, director of macroeconomics for Moody's Economy.com.
Finally, during the past nine months, the drop in household wealth has been larger since anything on record in the post-World War II period.
