That’s the ruling by the official arbiter of these things, the National Bureau of Economic Research. After reviewing all of the revised and updated data, the NEBR concludes that the recession lasted from December 2007 to June 2009, making it the longest recession in the period since World War II. The NEBR cautions:
In determining that a trough occurred in June 2009, the committee did not conclude that economic conditions since that month have been favorable or that the economy has returned to operating at normal capacity. Rather, the committee determined only that the recession ended and a recovery began in that month.
For its own analytical purposes, the NEBR would treat any economic downturn subsequent to June 2009 as a separate and unique event from the Great Recession.
