ninkorn,
Good data. I agree that this will be (probably already is) a deep recession. It's already lasted longer than the last 2 recessions and some economists are projecting GDP growth of negative 6% this quarter! Virtually all economists are also projecting negative GDP growth next quarter. No question this is the worst recession in some time and it probably has at least another year to go. Most predictions I'm hearing now call for an end to this recession in early 2010. That would make for a pretty long and severe recession.
However, during the great depression the unemployment rate hit 25% (I just checked). I think you have to compare the unemployment rate (not number of unemployed) to get an apples to apples comparison. Also I don't think you can use the NYTs "adjusted" unemployment rate unless you are comparing it to a similarly adjusted employment rate during the great depression. An apples to apples comparison would be 6.7% now vs 25% then. In addition I found this quote describing conditions during the great depression:
""Hoovervilles," or shantytowns built of packing crates, abandoned cars, and other scraps, sprung up across the nation. Residents of the Great Plains area, where the effects of the Depression were intensified by drought and dust storms, simply abandoned their farms and headed for California in hopes of finding a true "land of milk and honey." Gangs of unemployed youth, whose families could no longer support them, rode the rails as hobos in search of work. America's unemployed citizens were on the move, but there was no place to go that offered relief from the Great Depression. "
I just don't think that's where we're headed.
