Answer:
The Great Recession
Step-by-step explanation:
The Great Recession began in December 2007 and ended in June 2009, which makes it the longest recession since World War II. Beyond its duration, the Great Recession was notably severe in several respects. Real gross domestic product (GDP) fell 4.3 percent from its peak in 2007Q4 to its trough in 2009Q2, the largest decline in the postwar era (based on data as of October 2013). The unemployment rate, which was 5 percent in December 2007, rose to 9.5 percent in June 2009, and peaked at 10 percent in October 2009. (Robert Rich, federalreservehistory.org)
