Click on graph for larger image in new window.This graph shows the real GDP declines from the prior peak for post WWII recessions.
The recent recession was the worst since WWII (the peak decline was 3.83% in Q2 2009).
Even after the strong GDP growth in Q4 (due to inventory changes), current GDP is still 1.9% below the prior peak in real terms. If the recovery is sluggish - as I expect - it will take several more quarters to return to the pre-recession peak in real GDP.
