Recession in USA

This is a list of recessions that have affected the United States. Though economists define a recession as two quarters of negative GDP growth, the beginning and ending dates of U.S. recessions are officially determined by the National Bureau of Economic Research (NBER). The NBER defines a recession as, "...a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales." From 1945-2007 the NBER has identified 11 recessions; their average duration was 10 months (peak to trough). 

^{Most of the recessions listed here have affected economies on a worldwide scale; some of them are the Great Depression, the late 1980s recession, and the early 2000s recession. Recessions in one country are often grouped together with recessions in other countries that are related, and they commonly share a focal point as the cause of the recession.}
