So how many suicides are associated with the recession? Nobody knows, not yet. The statistics lag about three years, so the official Center for Disease Control numbers still predate the financial crisis. Right now, therefore, the reports remain anecdotal.

But looking at individual counties' or cities' data, there are ominous signs of a real spike. Some counties show no change. Others show dramatic climbs. In rural Elkhart County, Ind., where the unemployment rate is 13.7 percent, there were nearly 40 percent more suicides in 2009 than in a normal year. In Macomb County, Mich., where the unemployment rate is also 13.7 percent, an average of 81 people per year committed suicide between 1979 and 2006. That climbed to 104 in 2008 and to more than 180 in 2009.

The suicide prevention hotlines also show signs of stress. In Jan. 2007, as the recession started, there were 13,423 calls to the National Suicide Prevention Lifeline, a nationwide toll-free hotline. A year later, there were 39,467. In Aug. 2009, the call volume peaked at 57,625.
