Per the St Louis Fed:


I am less interested in the jobless rate from the last two years as much as the spike that occurred right after 9/11 in 2001. Presumably, the terror attack had a big effect on the economy as a short term shock, but the sustained stagnation for the period of 2002-2003 is interesting because I dont remember people becoming nervous even though the jobless rate spiked up to a rate that hadnt been seen since 1995.
